Hi, I have a 2466 Marshall Vintage modern and a VS412 marshall cab....comes with g12L's and want to switch to vintage 30? will that match work?? thanks
@lac365 guitar speakers are designed and voiced specifically for use in guitar cabinets, car speakers would not sound good, their frequency response is drastically different than that of a guitar loudspeaker. Speakers for music are designed for a wider range of frequencies and have a flat response over the range. Guitar speakers are very different, and actually shape your sound quite a bit. I can't recommend using anything other than a guitar speaker for your cabinet or combo amp.
ok i dont know if you know, but my amp is hissing, it kind of sounds like a kettle? so i dont know if its the speakers or the head. do you happen to have an idea?
@SimanGtr75 I'm fairly certain all the major manufacturer's are standardized in the hole placement for mounting their speakers. I'm not entirely sure though.
@neosonic66 I have a question, I have a small 20w amp with a 8'' speaker, and it sounds like shit, I wonder if I can change the 8'' speaker to a 10'' speaker... would it sound louder? Thanks.
@lookingatcrap you can mix wattages, just realize that the power is distributed evenly among the speakers. You're limited by your lowest wattage speakers, but if 80 watt speakers are your lowest, you should have no problems unless your amp outputs more than 320 watts (assuming you're using 4 speakers).
I have a fender hot rod deluxe from the early 2000s and the connecters are very tight I do not want to pull too hard and damage the speaker. Any suggestions
@SumThenfancy ensure that your connections are not soldered in to place. If they are, you'll have to de-solder the connections and then re-solder the new connections on. Most marshall cabinets use the quick connectors that I show in the video, but I've never worked on a fender cabinet, so I can't say for certain.
Wow, I have the 1960B and I thought the g12t75's were dark sounding, I also have an Egnater cab with Vintage 30's which I love thinking of swappng the drivers in the two cabs because I have a marshall head and what to get rid of the egnater cab, thank for the good video.
Yeah I think combo's can be replaced, but its much harder since its a tighter unit and all crammed together.
Thank you for doing this ish here. I now have enough info to get a 15" for my Peavey bass cab and replace the blown speaker in there. Im even wanting to replace the crappy speakers in small practice amps for experience purposes.
i have some questions, can you change speaker in a combo amp too? what speaker would you recommend for 80s hard rock/metal , i have a Peavey Vypyr 75w that has a blue marvel speaker if that helps, thanks!
Hi, I'm thinking of replacing the 1x10 speaker on my VT30 combo, but with only one speaker do I not need to wire the two middle connectors on the speaker
Thanks for this vid.I was going to get a tech to change the speakers for me,thinking there would be soldering involved.Did it in about 10 min. with your help,nothing to it
I don't believe he is telling the truth to say the G12T-75 speakers where to brite so he changed them out...I own them and I find they have huge mid and bass sound speaker...I actually find them great for rythem playing but lacking in leads.
I like the greenbacks but there is a differance between which ones you get...Some greenbacks are cheap made in China drivers that are on the low end price..
@JBL8863 I'm totally lying... just for fun. No, in my opinion the G12T-75's are too bright and lead to ear fatigue at high volumes very quickly compared to the greenbacks. Speaker preference is purely a matter of personal opinion, this video is here to demonstrate how to replace speakers, not which speakers are better. I'm not sure what you're attempting to accomplish here with your comment. I'm not saying you need to replace G12T-75's with Greenbacks. I'm saying I wanted to, here's how.
@neosonic66 I agree it'all about sound...I have a 1960 Lead slant cab & straight cab (full stack)...I changed out the drivers in the straight cab with 16 ohms Rocket 50 by celestion...
I commented on what you said regarding G12 speakers sounding bright for ya...Not from what I have put them through...I've used them in the following tube heads with low to mid gain sounds lacking thin crisp twang.
The speakers in my cab are mounted with 8 screws in each speaker, could I put in new speakers (veteran 30s) which only have 4 screws and leave the other 4 just empty?
Man a very Big Hug and thanks to your videos! its very useful especially to the people doesnt know how to upgarde or replacing their speaker.. cheers mate! tnx a lot!
If I were to mix two speaker models, would I connect those middle wires to the similar speaker or the one above it and continue your method? 2(Celestion Rocket 50's 8ohm) and 2(Eminence Texas Heat 8ohm). I plan on having either the Rocket 50's above or all of the speakers in an X shape.
@Arvains I've never heard of 15 ohm speakers... If you're seeing a '15' ohm speaker it's most likely in error. All guitar loudspeakers should be manufactured to impedances of 4, 8, or 16 ohms. The important thing is to replace your current speakers with speakers of the same impedance. If you don't, you need to make sure that you change your amp's output impedance to match the new impedance you just set up at the load (the speakers).
Those look like the made in China greenbacks right? I bought one locally and I was told by the guy that it was made in England. I ended up buying 4 more of the made in England ones. Not sure if there's a tone difference between them but I am sure the price is cheaper for China ones. The metal frames are a darker grey ...... almost bronze colour on the china ones and the greenpart has Made in England carved on the England ones.
does it matter that your replacing it with 25 watt speakers? or is impedance all that matters? i have the same cab and im thinking about getting some v30s to replace the g12 75s.. would that work?
@whitewalls1222 The speaker wattage does not matter as far as the cab is concerned. V30's are 60 watt speakers, so 4 of them means your cabinet will handle 240 watts, so as long as your amp doesn't output more than 240 your fine. My cabinet can only handle 100W since it's now 4x25 watt speakers, so a 150W mesa/boogie dual rec, could potentially blow my speakers if I cranked it. Long story short, speaker wattage totals just need to be equal to or greater than the peak output power of your amp
@neosonic66 oh, well. im using a 5150, im pretty sure its 120w, so that shouldnt be a problem.. did you use that same wires to hook the new speakers up? is it really that easy, just screw in the new speakers and hook em up like the old ones were?
@whitewalls1222 same wires, and it's really that easy... just make sure you get v30's that are the same impedance as the g12t75's in your cabinet now and you should be fine
Thank you for the video, it's absolutely usefully, I am thinking to change the speaker of my HT 40 Blackstar, it's a celestion seventy/80 for Vintage 30 (60watts 16oh), I was thinking maybe it's hard, but with your video, it's very easy.
I agree with PETRYZ.I would never replace a speaker unless the cab is face down.Especially if the screw posts are sticking out of the cab,speaker baffler.Much easier to align with less risk,and the use of two hands to insure stability.To each his/her own I guess.
Hey man, my amp doesnt have the wires that connect to the tabs, mine are soldered beside the tabs. Where do you get these kind of wires? I dont have a soldering iron either. its also a mesa 2x12
@GuitarRocks23455 those quick-disconnects are standard with that particular marshall cab. If your wires are soldered in, you'd have to get a soldering iron and disconnect them that way, then re-solder the wires when you install the new speakers. If you don't know how to solder, you can practice with some scrap wire until you're comfortable, otherwise you'll have to have someone else do it for you.
Thanks, dude. That was an extremely helpful guide to installing speakers. I never knew it would be so much easier than installing pickups. I'm thinkin now I'll run my Mesa OS 4x12 with V30s and G12k100s in an X pattern.
@petryz i weighed holding up the speakers while screwing them in, and taking the amps off the cabinet, disconnecting them, and reconnecting and putting them back up when i was done, and decided it would just be easier to hold up the speakers, in other words, laziness
Nice one! I have a Marshall JTM 410 cab with Celestion Goldback speakers and want to replace them with Greenbacks, seeing this means it is definitely gonna be my next project, thank you! :D
@slimmetalpickin I suppose you could do that. The big thing is make sure the speaker is capable of handling 60 watts. If it's not a 60 watt speaker, you'll blow it when you crank your amp up loud. That being said, a sub is designed for a low frequencies, and guitars are pretty much all mids... I don't think a car sub would sound good at all being used as a guitar loudspeaker, but electrically, it should work
@neosonic66 actually when using them WITH a normal guitar speaker...they sound pretty awesome...especially when playing with high gain and chugging.....but it does suck away some potential volume
I'd recommend laying the cab face flat on the ground (carpet that is not to scratch the tolex finish) when removing/installing the speakers as this would maki it easier than holding them upright.
Where do you purchase yor Celestion speakers? I have a 1966 Vox Berkeley II amp that had 2 Bulldog Gold 10" speakers. I believe these will give as close to the original Vox sound as possible. Do you agree?
have you ever had trouble with the switch on the back? I am getting weird things with mine, on mono only one speaker works, on stereo 3 work and the 4th is very faint or non existent.
remember that the chances of putting a screwdriver through your new speaker rises proportionately to the expense of the speaker and the cheapness of the screwdriver.
How, is it possible to convert/wire-up a mono cab into stereo? I use a laney 4x12 which is a mono cab, but would like to plug in my marshall 20/20, which requires a stereo load. Thanks.
@neosonic66 True however, if you buy a Marshall cab then buy new speakers to change over, it all adds up. Why not just buy the right cab with your preferred speakers to begin with. The 1960AX is a nice looking cab and has Greenbacks. Thanks.
@5150VanAlien You're right... if, you know exactly what you want out of a speaker cabinet from your first purchase. When I bought this cabinet 5 or 6 years ago, I didn't really understand the subtleties of speaker voicing, I was more just excited to get a half-stack. So for people in that position, instead of replacing the entire cabinet, you can breathe new life into an old cabinet without breaking the bank, and it's easy to do. That was my intent with this video.
@neosonic66 Thanks, I had a feeling that was the case. Since you've changed over to greenbacks, do you find that they can handle hard rock/metal ok? Also, which Marshall head have you got? I ask this second question because a 100 watt head into a 100 watt cab could push the speakers too hard and potentially blow them, especially at higher volumes.
@5150VanAlien I love the greenies, they are great for rock and metal. They don't have the natural scooped sound of a V30, but they are nice and warm and mid-rangy. I like mids, some prefer scooped, but not me... I have a marshall 1987x, the 50 watt plexi reissue head. I also have a 50 watt engl fireball for metal stuff, and the greenbacks sound great with it. But yeah, i'm not in danger of pushing them too hard, but hard enough to get some nice speaker distortion with the 50 watt heads.
@neosonic66 Cool, thanks for the insight. Like you I use ENGL and had the Fireball but sold it to buy the Savage 120. Great stuff ENGL and I run it through the ENGL 212 horizontal cab. Take care.
wow i didn't know it was that simple I just took a peak in the back of my 50 watt Marshall Vintage Modern Combo 2X12 only difference is that the speakers don't go to a circuit board but directly to a wire that goes in the speaker output on the amp
excellent vid.....but i have a question for anyone. i have a bugera 120 watt valve head running thru a marshall 1936 2X12. it has the G12T-75s in it and im not loving it. i was thinking of the V30s..if they are 60 watts each, will that be a perfect match for my amp, or do they risk getting blown? i don't run my amp past 5 on the volume
if you ran your amp completely dimed out and the gods of electricity didn't like you that day, there's a chance you'd blow a speaker, but it's very unlikely.
Amp power ratings are in RMS (root mean square), which without getting in to too much electrical theory equates to the high end average output of the amp. It's peak power can be higher, so under the right conditions the amp can produce bursts of sound greater than in your case 120 watts,
Can i use other speaker building my own cabinet? Speakers like peavy black widow or something like that? Or i need special speakers made for guitar like celestion?
Nice video! I'm looking to do what you have done (I may go for the G12H instead of the Greenbacks), and now I know what to expect when opening the back of my cab!
As an addition to the info here, I recommend NOT re-installing all the cab back screws until you test the cab, to make sure all the speakers are firing properly. I put 2 V30's into my 1936 a few years ago, and closed up the cabinet, only to find one speaker wasn't working!
I've never personally used the V30's, but I do know that a lot of people consider them the premiere speakers for metal right now. Some people also like to put two V30's in an X pattern on the 4x12 with 2 Greenbacks to combine the two flavors, but I don't think you can go wrong with V30's. Despite the name, V30's are NOT 30 watt speakers, they're 60 watt speakers, so 4 of them will have no problem handling a cranked 100 watt amp.
I use the very same Marshall cab in this video but with the G12H's which are 30 Watts each and has a little bit higher decibel sensitivity.
I use the G12H's with my Carvin Legacy head and would like to try Greenbacks with it. It is said that Steve Vai (who designed the Legacy amp) use Greenbacks, confirmed on his webpage and on a geartour but Carvin say that the matched cabinet they sell has V30's.
im getting a marshall mg250dfx, and its a 2x12 pushing out 230 watts with only two 50 watt speakers, if i play with the volume passed 5 or 6 alot, should i change out the speakers for something a little bit bigger? cuz i was going to change them out for a pair of mick thomson edition celestions, or should i just get a 2x12 extension cab, or is it fine the way it is?
I have a Mesa 212 F100 combo with G12 V30s (notGB) and my band hated the sound cuz we only used 5% of the amp volume and then miced, mixed, and ran to a PA. The speakers are killer but they need to be cranked to 30-50% power to hit the sweet spot, and that is loud! What would you recommend installing in a 2x12 avatar cab powered by the F100 to play along with the G12s? Great video by the way
I'm a fan of trying to match your speaker power rating to the amp output power rating, If your amp's outputting 100 watts, I wouldn't recommend putting 2 25 watt speakers in a 2x12 because you'd risk blowing them if you crank your amp. Try to find something with a minimum of 100 watt power handling, but don't go too far the other way, like 200 watt speakers that you'll never push. It's kind of tricky if you can't crank the amp, because you may never really be able to push those speakers.
sorry but.. i belive that's not correct to tighten the speaker mouting screws with a drill...you must do it with a screw driver and your hands in small amounts, in X pattern, if not, you can 'deform' the "chasis".... those look like a great speakers i use v30's in all my cabs, even fender's and you're right they more "modern" have a lot of low mids and are very loud so if you like to crank tube amps, its a bit harder to do it, it can be too loud for small places... or small rehearsal rooms.. : )
Great tutorial man, how are you liking the new speakers? I have a 1960A and have a really harsh/shrill/muddy tone with the stock speakers, and by replacing them I hope to get a much better tone.
I hear that the v30s are all that and a bag of chips, do you have any experience with them?
I am absolutely smitten with the greenbacks. I totally agree, the stock 1960A speakers were very harsh and had very ear-fatiguing highs. I was considering the V30's as well, I've heard nothing but rave reviews over them. I've not played through them though, but from what I understand, the greenbacks are going to give you a better vintage tone, the v30's are slightly better for a more modern tone.
great video - I have the same Marshall Cabinet - I have never opened it - are the original 75s 8 or 16 ohms? did you find the 30s were tighter or looser than the 75s? Are the 30s as clear as the 75s? I like the clarity of the 75s but sometimes find that cab to be a bit boomy in the bass dept - I use 6L6s - EL34s might react a lot differently with the speakers - I have never heard greenbacks
Originals are all 16ohms, the greenbacks are a much warmer speaker than the 75's. The top end in my opinion is a lot smoother on the greenbacks, they don't have as much low end punch as the 75's, but the mids are much more pronounced. I wanted them because of the mid-range and the warmth. I've not heard them with 6L6's though, I use EL34's and Tung-Sol 12ax7's in the preamp. Another reason I didn't want the 75's anymore is because my head's are 60 and 50 watts, so I can't push 75's well.
EL34s eat up bass, especially in a Marshall + with 50/60w amps I can see why you wanted Greenbacks in that cab - Tungsol 12AX7s are also a warmer preamp tube - I use 6L6s so the 75s balance out the tone + I use GTmullard 12AX7s - I have a vox with EL34s on the way - I do like a bright tone - I will probably hunt down some vintage 30s - I might even try & put 6L6s in the vox - Thanx for the video & response - you have been very helpful
2. also for a live sound, I've heard of a lot of people putting greenies and V30's in an X pattern on their 4x12's, with 2 of each speaker, it's supposed to blend really well. I went with all greenbacks not only because I love the vintage tone, but for recording purposes, I wanted to be able to record exactly what I hear, or close to it, which I thought would be an issue if I had a blended speaker combination int he cabinet
yes, just make sure you match the impedance of the speaker you're replacing.... V30's are available in 8 and 16 ohms, not sure what's currently in the valveking, but just make sure you get the same impedance and you'll be fine
Yeah you can just as long the ohms and physical size are the same. There is only a 5 watt difference.
According to google the speaker is 8 inches on both systems. The hartke b200 is 20 watts. The Laney RB1 is 15 watts. Just ohm them out. If they are close in Ohms will you be fine.
The wattage on the b200 is 5 watts more than the laney rb1. That will work just fine it can never hurt having headroom for wattage. 5 Watts is not that much. Most likely it will be 8 ohms too. Go ahead and replace it.
Just keep the + and -- correct when replacing it. Otherwise it will be out of phase and sound like crap.
great explanation, however a brief explanation of ohm changes and whether the speakers were wired in parallel or series would be helpful. so to those of you out there replacing your speakers make sure you match the original speakers ohms or adjust your amp to match the new ohmage.
good point, impedance matching is very important for tube amplifiers, a mismatched impedance could result in a blown output transformer, and a hefty repair bill... if you're swapping speakers out 1 for 1, replace with the SAME impedance as your old speakers!
I'll be doing tone demo's, I just wanted to give the speakers a chance to break in first, so they don't have that stiff, brand-new, bright tone... more to follow!
this will be very helpful to lots of people I'm sure ..we all like to tinker..and this will come in handy. Thanks for reminding us NOT to blast the thing untill the new speakers have had a chance to stretch out a little..davido
I second the motion to hear this bad boy on your next video :)
I bought this cabinet years ago, so had I known more back then I would have purchased a greenback loaded cab to begin with, but this was much cheaper than buying a whole new cabinet this time around :)
The eternal procrastinator I am, I still haven't bought my Marshall stack (I'm wisely waiting 'till I finish my final Univ tests) so I'd like to know more what speakers work better with what kind of music. :-)
stock G12T-75's are really bright, but some say they're good for modern high gain, I disagree, I would say celestion Vintage 30's are the best for a modern scooped metal sound, and most modern hard rock applications. 25 Watt greenbacks are great for classic rock tone because they break up easily and are nice and warm sounding, for that classic compressed warm overdrive.
Very helpful and informative. I feel totally confident in my ability to replace my speakers by myself now. Thanks a lot, man.

does it matter that your replacing it with 25 watt speakers? or is impedance all that matters? i have the same cab and im thinking about getting some v30s to replace the g12 75s.. would that work?
whitewalls1222 1 year ago
@whitewalls1222 The speaker wattage does not matter as far as the cab is concerned. V30's are 60 watt speakers, so 4 of them means your cabinet will handle 240 watts, so as long as your amp doesn't output more than 240 your fine. My cabinet can only handle 100W since it's now 4x25 watt speakers, so a 150W mesa/boogie dual rec, could potentially blow my speakers if I cranked it. Long story short, speaker wattage totals just need to be equal to or greater than the peak output power of your amp
neosonic66 1 year ago
@neosonic66 oh, well. im using a 5150, im pretty sure its 120w, so that shouldnt be a problem.. did you use that same wires to hook the new speakers up? is it really that easy, just screw in the new speakers and hook em up like the old ones were?
whitewalls1222 1 year ago
@whitewalls1222 same wires, and it's really that easy... just make sure you get v30's that are the same impedance as the g12t75's in your cabinet now and you should be fine

Thank you for the video, it's absolutely usefully, I am thinking to change the speaker of my HT 40 Blackstar, it's a celestion seventy/80 for Vintage 30 (60watts 16oh), I was thinking maybe it's hard, but with your video, it's very easy.
InfiernoSupremo 1 year ago
I agree with PETRYZ.I would never replace a speaker unless the cab is face down.Especially if the screw posts are sticking out of the cab,speaker baffler.Much easier to align with less risk,and the use of two hands to insure stability.To each his/her own I guess.

Hey man, my amp doesnt have the wires that connect to the tabs, mine are soldered beside the tabs. Where do you get these kind of wires? I dont have a soldering iron either. its also a mesa 2x12
GuitarRocks23455 1 year ago
@GuitarRocks23455 those quick-disconnects are standard with that particular marshall cab. If your wires are soldered in, you'd have to get a soldering iron and disconnect them that way, then re-solder the wires when you install the new speakers. If you don't know how to solder, you can practice with some scrap wire until you're comfortable, otherwise you'll have to have someone else do it for you.

Thanks, dude. That was an extremely helpful guide to installing speakers. I never knew it would be so much easier than installing pickups. I'm thinkin now I'll run my Mesa OS 4x12 with V30s and G12k100s in an X pattern.

Why didn't you put the cabinet face down?
petryz 1 year ago
@petryz i weighed holding up the speakers while screwing them in, and taking the amps off the cabinet, disconnecting them, and reconnecting and putting them back up when i was done, and decided it would just be easier to hold up the speakers, in other words, laziness

can i run 2 green backs and 2 g12's with a 50 watt jvm? I think the stock is bright and compressed
kissrocks45 1 year ago
@slimmetalpickin I suppose you could do that. The big thing is make sure the speaker is capable of handling 60 watts. If it's not a 60 watt speaker, you'll blow it when you crank your amp up loud. That being said, a sub is designed for a low frequencies, and guitars are pretty much all mids... I don't think a car sub would sound good at all being used as a guitar loudspeaker, but electrically, it should work

@neosonic66 actually when using them WITH a normal guitar speaker...they sound pretty awesome...especially when playing with high gain and chugging.....but it does suck away some potential volume

I had a little problem when removing a Speaker out of my Vintage Modern Combo When i took out the screws the speaker was still stuck :S
Probably if i wanted i could have lifted the entire amp pulling the speaker up it just wouldn't come off almost like it was glued
What do i do now XD
lordakamai 1 year ago
I'd recommend laying the cab face flat on the ground (carpet that is not to scratch the tolex finish) when removing/installing the speakers as this would maki it easier than holding them upright.

@neosonic66 True however, if you buy a Marshall cab then buy new speakers to change over, it all adds up. Why not just buy the right cab with your preferred speakers to begin with. The 1960AX is a nice looking cab and has Greenbacks. Thanks.
5150VanAlien 1 year ago
@5150VanAlien You're right... if, you know exactly what you want out of a speaker cabinet from your first purchase. When I bought this cabinet 5 or 6 years ago, I didn't really understand the subtleties of speaker voicing, I was more just excited to get a half-stack. So for people in that position, instead of replacing the entire cabinet, you can breathe new life into an old cabinet without breaking the bank, and it's easy to do. That was my intent with this video.
neosonic66 1 year ago
@neosonic66 Thanks, I had a feeling that was the case. Since you've changed over to greenbacks, do you find that they can handle hard rock/metal ok? Also, which Marshall head have you got? I ask this second question because a 100 watt head into a 100 watt cab could push the speakers too hard and potentially blow them, especially at higher volumes.
5150VanAlien 1 year ago
@5150VanAlien I love the greenies, they are great for rock and metal. They don't have the natural scooped sound of a V30, but they are nice and warm and mid-rangy. I like mids, some prefer scooped, but not me... I have a marshall 1987x, the 50 watt plexi reissue head. I also have a 50 watt engl fireball for metal stuff, and the greenbacks sound great with it. But yeah, i'm not in danger of pushing them too hard, but hard enough to get some nice speaker distortion with the 50 watt heads.
neosonic66 1 year ago
@neosonic66 Cool, thanks for the insight. Like you I use ENGL and had the Fireball but sold it to buy the Savage 120. Great stuff ENGL and I run it through the ENGL 212 horizontal cab. Take care.

Will this method work the same for replacing a combo amp's speakers? sorry for the noob question im kinda new to this.

should be relatively the same, just make sure your amp is unplugged and the speakers are disconnected from the actual amplifier section
neosonic66 2 years ago
wow i didn't know it was that simple I just took a peak in the back of my 50 watt Marshall Vintage Modern Combo 2X12 only difference is that the speakers don't go to a circuit board but directly to a wire that goes in the speaker output on the amp
lordakamai 2 years ago
So 2 of the speakers ain't directly connected with the circuit board? Is that the speakers that is 180 out off phase?

they should be in phase, since the bottom speakers are connected to the same pos / neg poles on the top speakers

excellent vid.....but i have a question for anyone. i have a bugera 120 watt valve head running thru a marshall 1936 2X12. it has the G12T-75s in it and im not loving it. i was thinking of the V30s..if they are 60 watts each, will that be a perfect match for my amp, or do they risk getting blown? i don't run my amp past 5 on the volume
glamboy7373 2 years ago
if you ran your amp completely dimed out and the gods of electricity didn't like you that day, there's a chance you'd blow a speaker, but it's very unlikely.
Amp power ratings are in RMS (root mean square), which without getting in to too much electrical theory equates to the high end average output of the amp. It's peak power can be higher, so under the right conditions the amp can produce bursts of sound greater than in your case 120 watts,

Nice video! I'm looking to do what you have done (I may go for the G12H instead of the Greenbacks), and now I know what to expect when opening the back of my cab!
As an addition to the info here, I recommend NOT re-installing all the cab back screws until you test the cab, to make sure all the speakers are firing properly. I put 2 V30's into my 1936 a few years ago, and closed up the cabinet, only to find one speaker wasn't working!

Hey man great video.
i have a a 100 watt amp that i push to probably about 93 DB. wich is not all the way up.
thats about 6.
wich is right were the amp starts to clear up and sound (tube amp)
do you think that V30s are right for me?
I play metal. i rarly have the chance to crank it.
but i want the power to of course because i need it to play with people hah.
let me know. : )
mcpeepants1821 2 years ago
I've never personally used the V30's, but I do know that a lot of people consider them the premiere speakers for metal right now. Some people also like to put two V30's in an X pattern on the 4x12 with 2 Greenbacks to combine the two flavors, but I don't think you can go wrong with V30's. Despite the name, V30's are NOT 30 watt speakers, they're 60 watt speakers, so 4 of them will have no problem handling a cranked 100 watt amp.
neosonic66 2 years ago
Anyone compared the Greenbacks to G12H's?
I use the very same Marshall cab in this video but with the G12H's which are 30 Watts each and has a little bit higher decibel sensitivity.
I use the G12H's with my Carvin Legacy head and would like to try Greenbacks with it. It is said that Steve Vai (who designed the Legacy amp) use Greenbacks, confirmed on his webpage and on a geartour but Carvin say that the matched cabinet they sell has V30's.

im getting a marshall mg250dfx, and its a 2x12 pushing out 230 watts with only two 50 watt speakers, if i play with the volume passed 5 or 6 alot, should i change out the speakers for something a little bit bigger? cuz i was going to change them out for a pair of mick thomson edition celestions, or should i just get a 2x12 extension cab, or is it fine the way it is?
wxp24 2 years ago
I have a Mesa 212 F100 combo with G12 V30s (notGB) and my band hated the sound cuz we only used 5% of the amp volume and then miced, mixed, and ran to a PA. The speakers are killer but they need to be cranked to 30-50% power to hit the sweet spot, and that is loud! What would you recommend installing in a 2x12 avatar cab powered by the F100 to play along with the G12s? Great video by the way
phxrocks69 2 years ago
I'm a fan of trying to match your speaker power rating to the amp output power rating, If your amp's outputting 100 watts, I wouldn't recommend putting 2 25 watt speakers in a 2x12 because you'd risk blowing them if you crank your amp. Try to find something with a minimum of 100 watt power handling, but don't go too far the other way, like 200 watt speakers that you'll never push. It's kind of tricky if you can't crank the amp, because you may never really be able to push those speakers.
neosonic66 2 years ago

HKP1994 2 years ago
sorry but.. i belive that's not correct to tighten the speaker mouting screws with a drill...you must do it with a screw driver and your hands in small amounts, in X pattern, if not, you can 'deform' the "chasis".... those look like a great speakers i use v30's in all my cabs, even fender's and you're right they more "modern" have a lot of low mids and are very loud so if you like to crank tube amps, its a bit harder to do it, it can be too loud for small places... or small rehearsal rooms.. : )
thewretchedrod 2 years ago
Great tutorial man, how are you liking the new speakers? I have a 1960A and have a really harsh/shrill/muddy tone with the stock speakers, and by replacing them I hope to get a much better tone.
I hear that the v30s are all that and a bag of chips, do you have any experience with them?
sacamano79 2 years ago
I am absolutely smitten with the greenbacks. I totally agree, the stock 1960A speakers were very harsh and had very ear-fatiguing highs. I was considering the V30's as well, I've heard nothing but rave reviews over them. I've not played through them though, but from what I understand, the greenbacks are going to give you a better vintage tone, the v30's are slightly better for a more modern tone.
neosonic66 2 years ago
great video - I have the same Marshall Cabinet - I have never opened it - are the original 75s 8 or 16 ohms? did you find the 30s were tighter or looser than the 75s? Are the 30s as clear as the 75s? I like the clarity of the 75s but sometimes find that cab to be a bit boomy in the bass dept - I use 6L6s - EL34s might react a lot differently with the speakers - I have never heard greenbacks
Diary81 2 years ago
Originals are all 16ohms, the greenbacks are a much warmer speaker than the 75's. The top end in my opinion is a lot smoother on the greenbacks, they don't have as much low end punch as the 75's, but the mids are much more pronounced. I wanted them because of the mid-range and the warmth. I've not heard them with 6L6's though, I use EL34's and Tung-Sol 12ax7's in the preamp. Another reason I didn't want the 75's anymore is because my head's are 60 and 50 watts, so I can't push 75's well.
neosonic66 2 years ago
EL34s eat up bass, especially in a Marshall + with 50/60w amps I can see why you wanted Greenbacks in that cab - Tungsol 12AX7s are also a warmer preamp tube - I use 6L6s so the 75s balance out the tone + I use GTmullard 12AX7s - I have a vox with EL34s on the way - I do like a bright tone - I will probably hunt down some vintage 30s - I might even try & put 6L6s in the vox - Thanx for the video & response - you have been very helpful
Diary81 2 years ago
2. also for a live sound, I've heard of a lot of people putting greenies and V30's in an X pattern on their 4x12's, with 2 of each speaker, it's supposed to blend really well. I went with all greenbacks not only because I love the vintage tone, but for recording purposes, I wanted to be able to record exactly what I hear, or close to it, which I thought would be an issue if I had a blended speaker combination int he cabinet

yes, just make sure you match the impedance of the speaker you're replacing.... V30's are available in 8 and 16 ohms, not sure what's currently in the valveking, but just make sure you get the same impedance and you'll be fine

can you replace a different branded speaker to a different branded amp?
i'm gonna replace my Laney RB-1 speaker (terrible speaker buzz) to a Hartke B200 speaker.
is it ok?
need urgent answer
gunlak 3 years ago
Yeah you can just as long the ohms and physical size are the same. There is only a 5 watt difference.
According to google the speaker is 8 inches on both systems. The hartke b200 is 20 watts. The Laney RB1 is 15 watts. Just ohm them out. If they are close in Ohms will you be fine.
jimmy101112000 2 years ago
so i could just replace it with the b200 speaker with no problems at all?
can the wattage difference be an issue?
the default ohms of the rb1 is 8.
can't find any info on the b200
gunlak 2 years ago
The wattage on the b200 is 5 watts more than the laney rb1. That will work just fine it can never hurt having headroom for wattage. 5 Watts is not that much. Most likely it will be 8 ohms too. Go ahead and replace it.
Just keep the + and -- correct when replacing it. Otherwise it will be out of phase and sound like crap.
jimmy101112000 2 years ago
yeah i know.. i already opened my amp 1 time.,
but mine is soldered... should i take it to a shop?
i know how to solder but i mess up always..
gunlak 2 years ago
Do the pop test with a battery. 9 volts battery will work.
When the speaker is connected right the cone will move away from the magnet. Mark the terminals to how the battery was connected this time.
If the cone moves towards the magnet it is reversed.
Just go ahead and switch them out and solder them. Its only 2 wires. Just keep the polarity correct and you will be fine.
The only issues is you might drip solder or poke a hole in the cone. Keep a damp paper towel under the terminals.

great explanation, however a brief explanation of ohm changes and whether the speakers were wired in parallel or series would be helpful. so to those of you out there replacing your speakers make sure you match the original speakers ohms or adjust your amp to match the new ohmage.

good point, impedance matching is very important for tube amplifiers, a mismatched impedance could result in a blown output transformer, and a hefty repair bill... if you're swapping speakers out 1 for 1, replace with the SAME impedance as your old speakers!

stock G12T-75's are really bright, but some say they're good for modern high gain, I disagree, I would say celestion Vintage 30's are the best for a modern scooped metal sound, and most modern hard rock applications. 25 Watt greenbacks are great for classic rock tone because they break up easily and are nice and warm sounding, for that classic compressed warm overdrive.
