@MasterDJRenn : When you change a driver of one with different specifications, the crossover needs to be changed to suit the new driver. And yes, if you change the tweeter of a speaker, the woofer is also affected and the sound of it can change too.
It is obvious for so many reasons that the new selenium kicks the ASS out of the crappy little JBL (probably made in china) driver.
@nickacil The video instructs to simply swap out the JBL driver for the Selinium....Thats exactly what i did....Yes the crossover frequency will change due to different driver specs, but i fail to see how that would effect the woofer. Anyways, i did a side by side wit both drivers but i used an electronic crossover set to 2.5k 12db/octave and yes the Selenium sounded warmer and had extended highs but for all out loudness.....the JBL demolished the Selinium.....You really do get what you pay for.
@MasterDJRenn : Oh, ya, definitely when you change from a specific tweeter to any other type even with the same specs. the sound of the woofer changes because the crossover works in conjunction to the changes of the tweeter altering the roll off frequencies of the woofer.
Your crossover at 2.5 K is perfect at 12 DB 2 coils, 2 caps and a matching resistor for the balance for the unit itself.
See, JBL used to be a HI-FI company, and was nothing like the junk today.
@nickacil I still dont see how it would change the woofers crossover point.....If you remove all the high pass filter components, the xover point of the woofer remains the same cause they are independent of each other.
I know because I have Altec A7/ 500 VOTTs. Even when I changed to a different woofer, the highs were affected, and vise versa. Not all of this can be shown on paper. The filtering network of the tweeter is also a factor in the sonic characteristics of the woofer as they both in operation with each other.
OK, another example is that the DCR on both tweeters CANNOT both be the exact same along with the efficiency which also play a part.
@MasterDJRenn : Your not listening to what I said. If the change in audio cannot be shown on paper doesn't mean the crossover point changes but rather the character. There is phasing and acoustical changes NO MATTER WHAT, sometimes for the worse, sometimes for the better.
Still about 20% or more of the tweeter changes can affect the character of the woofer.
Now, if you have low grade equipment that is by no means HI-FI, the MID-FI equipment wouldn't be so sensitive as to show. Sucks eh?
@MasterDJRenn : A speaker doesn't have to be bi-amped as to have separate crossovers for woofer and tweeter. That is more for impedance matching. Bi-amp is better, I agree. I do have that, but for power consumption reasons I only use the EICO HF-35 mono amps for the Vitavox GP-1s with EV T-35s along with the 15" Wharfdale alnicos. All is hooked up to the Vitavox CN-232 crossovers and are at 16 ohms.
@nickacil EICO?????? Wow, my dad use to work for EICO like 30 years ago and i use to build the Eico kits as a kid.....PS what part of the world are you located? A lot of the brands you are mentioning dont really exist it the US.....
@MasterDJRenn : When I bi-amp, I use the Dunlap Clarke Dreadnaught 500 power amp for JBL 2225s, and for the Wharfdales being lower power, there are many good solid state amps to use that put out less than 50 watts like a Dynaco Stereo 80 (not the new tube amp) solid state.
@MasterDJRenn : Oh, if you are curious, I use Marantz Consolettes for preamps on one system and on the other system I use a Mackie SR24-4 mixing preamp having a 4 bus out.
The bi-amp (mixer) is for DJ, and the Marantzs are for home use.
@MasterDJRenn : I will be getting a pair of subwoofers for tri amping and also have a center channel. People automatically think a subwoofer when bi-amping, but no, the woofers I have now will only go to about 125HZ, and JBL 2225s are more of a woofer midrange (NOT a subwoofer). Something 18" would be nice, and would have to check out what is available. So for now it is bi-amp.
You don't need to bi-amp with the efficiency of the wharfdales that go to 25HZ having a 14LB alnico magnet.
@MasterDJRenn : Sir, I don't mean to get into a show down with you. I'm just conversing out of interest to my hobby. Just a hobby I had since I was 12 years old! I'm 49, and still love the art of HI-FI accuracy especially if I do all of the repairs and mods myself.
I have worked in TV and used stereo stores repairing.
Now, if I must bring out the artillery, there is no turning back.
@nickacil Hahahahah dont know what i said that warranted that response, but yea, like you i have always been interested in audio and im 42 years old, not much younger than you....you seem to be more into the sonic quality where as im into pure SPL and sound reinforcement....and yes i too repair electronics, i built a Heathkit AA-1640 when I was 10 years old...still have it to this day....
@nickacil I have a Crown Xti 6000 2 Xti 4000's and an Xti 1000.....Everything is electronically crossovered VIA the on board DSP on each amp.....Passive crossovers simply cant compare, and besides ive pulled them out of the JBL's JRX 125 and wired the box bi amped....I have much more control of the drivers and it sounds waaaaaaaayyyyyy better....
@MasterDJRenn : I have added an Electrovoice T35 tweeter with its own independent crossover at 10K, and did nothing to the woofer or existing crossover. The bass improvement is utterly amazing and the fullness in the midrange just opened right up, all because of adding super tweeter.
selenium is owned by jbl/harmann .most selenium drivers fits the cheep jbl systems ,if the driver has higher db ,than the old one ,use a l-pad off 2pc of 20watt resistors ,on expensive jbl systems ,selenium will be no upgrade
Это всё лажа, там режектор в кроссовере стоит, надо и его перестраивать под другой драйвер, и вообще, без этого режектра схема кроссовера для драйвера выглядит как первый электричесий порядок.

you may NEWER change driver like this as crossover is not calculated for impedance of new driver,so you change compleet configuration end sound of speaker,end possible make amp work what can result in broken amp... speaker sistem is more komplex then poping speakers in end out...
@jigibao This is very true. You shouldn't switch drivers unless you are completely sure that the maginitude response, impedance curve and the phase response are identical to the old drivers. But if something miraculous has happened and all these line up, you are still dealing with sensitivity mismatching causing the speaker to shift the crossover point and trowing the sound off balance. This all can be avoided by modifying the xo accordingly. I don't know how this can blow your amp though..?
I was given a set of the 2x15s with nuntin inthem so I pull crossover out put a plate over hole now I can bi amp them. I put 2 eminent kappa 15s in each speaker along with a generic 1 1/4 bolt on lens with eminent drivers. Couldn't be happier. I strongly recommend the bigger bolt on driver and removing crossover and use biamp. I would never settle for less. I am even doing them to my other two I bought (to make a set of 4)
Hi men, Nice Vid. But it doesn't matter if a driver is heavyer or not, or if a woofer has more weight than another, this doesn't mean one is better than the other. Jbl uses neodynium on most of their components, (y think no on the jrx systems). But a jbl 400RMS woofer from a MRX115 series, weights 2kg, and it sounds great. A normal woofer of that power, will be on 5 6 or even 7 kgs. JBL eon self powered 515 450 RMS wheigts 14.9kg. it doesnt mean than one of 40kg is better.
@DHood72 Yes, the MRX is a JBL PRO SERIES, those have better components and the sound is much more clear than the MRX series. Perhaps the selenium driver is better than the one in JRX, but no on the MRX. Watch the features on the JBL official site. What Im saying, is that you cant say a driver is better than another, or a woofer is beter than another because it weight's more. Technology gets forward, and each day, drivers and woofers are made with loght weight, and more power.
JRX series are good cuz THEY DONT FKING MAKE U POOR. i hate ppl who hate JBLs cheaper brand....why would they make a cheaper version and spend LOTS of time making it good? its good enough as is for what he and most people do...basically 90% of the crowd would NOT know a MRX vs a JRX series when playing. lmfao
I did a similar upgrade to my Tapco dual 15" speakers. They had the little stock driver and after blowing a pair of them, I went to the local speaker parts store and picked up a pair of the big Selenium 1" throat drivers similar to what Brian installed in his JBLs. The difference in sound was incredible and I havent blown any drivers nor does the speaker go into shutdown mode after having too much high end going to the horns. All you guys who poopoo changing drivers should use your ears.
hy brian!i listen your test and seem to me that jbl has a up frecv in comparation with selenium how has a low frecv.SELENIUM is a biggger dif sow it sound a lot more spl. sow ,if you put selenium into the speaker you would have a clenar sound but not sow hi sound ,I chose also selenium because you don t make hi fi aplication and you need spl .thancks!enjoy practice!
it definitley makes a diffrences...I was wondering if these would fit on my b 52s. the stock driver gave out and im looking on replacing them with some stock ones from b-52. or some like these..anyone got some feedback, holler at me?
The Selenium isn't a shitty after-market driver - it's a good quality brazilian product, clearly superior to the regular chinese stuff. The result could be better if the cross-over were matched to the new driver.
As someone who has experience building sound systems, and understands most of the science behind it I can't recommend 'going with it' First these drivers are tested in the lab to work with one another. Specifically, the phasing becomes problematic when using other drivers because the non stock driver could be having some cancelation where the frequency overlaps with the woofer. Also, as many users pointed out, these will be rough to stand next to, again JBL tests this type of thing.
Good video request but can not be changed in a way because crossoveri drivers that is installed inside which makes frequency sharing Bowl is working for them drajveri performance of a new father ...
Puxa, Sr. Homero Sette ficaria feliz com esse video gringo! Substituindo o drive JBL pelo Selenium, que felicidade! Porém apesar do D210ti ter muito mais capacidade e qualidade, ele manteve o divisor original, certamente dimensionado para o driver de bobina menor. Mesmo assim a troca fez uma grande diferença. Valeu!!
You are a complete fuck wit! Why would you replace perfectly good JBL compression drivers with a shitty after-market driver? Those particular drivers are optimized for use with the cross-over & enclosure design, but then again what can we expect when a DJ is fucking around with audio gear!

The Stock JBL Drivers have a "limited frequency response" meaning they are cheap chinese junk. JBL went off-shore for its lower end products. The Selenium are made in Brazil and are a much more superior product. I did the hot-rod and it's awesome! Just look on ebat for the original drivers, they have replacements galore because you blow them out because of how cheap they are. And there are a boatload of used one on there too. So ya think they are any good?? IMHO
WOW Nice Video But U just distroyed a Great Pair of JBL Cabs, From this video, the sound of the stock JBL driver had a BIGGER HF presents, and U can hear it in this video. the new driver u put in the jbl is a good one BUT the JBL driver is a wound ribbon driver that can punch out higher SPL at lower power. Nice way to screw up 40 years of speaker testing and design work.
@kyle2284 im pretty sure you got that mixed up, the new drivers are that have better high frequency response, maybe you misunderstood which side was the new drivers
Brian, I have a pair of JBL SF15 speakers and want to hotrod them. I think they have the same horn as the JRX-115. Since these are 8ohm speaker cabs, do I need a 16ohm driver? I think I saw 8ohm on the driver you installed. Does that drop your ohm load to 4? Please help.. Thanks!
When I saw this I thought, what about the different sensitivity, what about the extra weight and what about the reverse polarity. The reverse polarity causes a huge dip at the cross-over frequency. each speaker is at -3dB and out of phase. But the standard 2412 drivers are a bit harsh. It's not as simple as just changing drivers, you need to pad them down. I bet they squeal like crazy now!!! That's my two cents...
In addition to all that has been said wrt to the technical aspect of what Brian did. I would not recommend that the JBL JRX-115 be modified because it was engineered with specifications for optimized performance of each component together. The selenium driver has a larger displacement and therefore would affect the performance of the 15". It may seem insignificant, but am sure JBL would say it is.
the selenium d210ti are discontinued, you'll have to buy the d220ti. the price is about $46.00. I replaced my jbl mrx515 hf driver with the selenium d220ti and couldn't believe that they actually sound better the original jbl drivers. It's was hard for me to believe this was possible but it's true. spend the $46.00 and see for yourself. Don't let some idiot tell you different. also make sure you buy the 8ohm driver not the 16 ohm.
@djteknovibe the way I see it, you gotta trust what you hear and there is a definite difference in the sound...so why not do it? There's no harm in it? Who makes the rules when it comes to modifying your own equipment? I'm thinking of getting these speakers and may just do this mod myself.
what happens when the weak plastic horn doesnt support the big heavy new hf unit? put that cabinet down with a slight jolt and the plastic horn will crack no problems
all i hear is a difference in hf volume which would suggest you have ruined the balance the cabinet (which sounds great as it is, considering its in the budget range).
@richg101 na it wont damage the horn, i have the same speakers and those horns are rock solid! and if truth be told the original drivers are very weak
Hi, I found your video to be very helpful. With only stock computer speakers, it's hard to tell the difference in sound quality but I got what I needed! Thanks for your efforts!
On the camera, the sound is easier on the ears with the stock drivers, but I can tell that the stock drivers are much more muffled sounding and the new drivers are hitting proper highs. If I could hear the speakers in real life, it would be like adding the &fmt=18 extension code to a music video, or the difference between good horn loaded and direct tweeters. I have some horn tweeters on my stereo speakers and they are sounding much crisper and I have to set the treble eq lower.
Nothing the speaker just moves in reverse polarity.. Some people say they can hear the slightest change in sound when they are opposite but usually that isn't the case.
IF you want to upgrade your Jrx 115 cabs !!!! Get the selinums 220ti s they dont have the 210 anymore just got three of them and they sound like la Jbl Srx series ! un real ! :)
This video has a slight mistake, JBL drivers are positive voltage at red terminal for rearward cone movement, this is opposite to most manufacturers (including selenium). Therefore you should wire the seleniums the opposite way round so it looks as if they'd be out of phase.
One more comment - use Teflon tape (typical plumber's toolbox item - the Home Depot or Ace will have it) when installing screw-on horn drivers. They'll be slightly tougher to screw on, but they'll make a perfect vibration-free seal between the compression driver and the horn throat.
The JBL compression drivers in the JRX are very marginal (to meet a price point; good compression drivers are expensive and difficult to manufacture). Thus, they have a reputation of blowing easily. I recall being at a rock show in a small auditorium in my freshman year with the dual-15" JRXes where one driver went halfway through the show, and the other driver went about 30 minutes before the show ended. The speakers shouldn't have been overworked too badly -- both the woofers were still good.
i have dj'ed at a hall for 350 people on stands high up with an equalizer sound hella good greaat for the money MONEY WELL SPENT you will not be dissapointed
u just mest up a pair of jbl speakers the reason jbl dont make those horns that tingy is so you can crank them up and people dont have to plug there ears when they are at your show ! to much treble no and mid
Hello Brian, very interesting video, but I couldnt identify a good diference of sound in this video quality, but, have you take some measures of diferents drivers to verify a really diference and good flat sound? you must consider a diference in sensitivy of the new driver, it could produce a bad step in dbs with the LF drivers.
Please, if you have more information and tests of it, tell us.
Yeah, but your missing out on all the frequencies between 12kHz and 20kHz. Humans can hear up to approximately 20kHz so with the new drivers you can hear the music the way it is meant to be heard. Also that warm tone is probably actually distortion from the driver attempting to play those higher frequencies.
it is difficult to judge just by wattage, a speakers wattage is actually just a measurment of the amount of power the speaker needs to turn so much electrical energy in to sound energy, there are other much more important figures you need to be looking at when buy pro-audio, such as sensitivity, db spl levels and frequencie response, you only really need to look at the wattage when looking to be an adequate amp. wattage is a measurment of "loudness" , your better looking at db spl levels!
Hey Brian. I've been thinking about replacing the drivers in my Yamaha S12e speakers...if I get the right sized horn, would the D210Ti's work well in them? I might get a new low driver.
sorry, I don't understand much English, so I did understand the name and the model of the new driver you use for your jbl, I only understand "selenium" but not wich model... Do you think this could be ok also for the jrx-112 (the difference should be 12" woofer instead of 15" like yours). Thanks.
Even with the cheezy video recorder microphone, I can hear the difference. The new driver is more brighter, the highs are more detailed and clear. The stock ones just sound "muddy". Hard to believe that comes standard with JBL products.
i just did this mod to my jrx 115 cabs just like in the video.. it makes the highs very clean and not as harsh as the stock drivers.. i highly reccomend this mod.
Yeah I like the JRX series from JBL. The reason I bought them is because I liked the sound of them and the price point as well. I don't know how these speakers are priced in Europe compaired to EV, RCF, etc. Thoes brands may be a better choice depending on the price difference.
Stop smoking man. For your own good and my sanity tho I think the latter is too late.

Hi men, Nice Vid. But it doesn't matter if a driver is heavyer or not, or if a woofer has more weight than another, this doesn't mean one is better than the other. Jbl uses neodynium on most of their components, (y think no on the jrx systems). But a jbl 400RMS woofer from a MRX115 series, weights 2kg, and it sounds great. A normal woofer of that power, will be on 5 6 or even 7 kgs. JBL eon self powered 515 450 RMS wheigts 14.9kg. it doesnt mean than one of 40kg is better.

@Tomii87 So are you recommending the MRX115 drivers?
DHood72 1 year ago
@DHood72 Yes, the MRX is a JBL PRO SERIES, those have better components and the sound is much more clear than the MRX series. Perhaps the selenium driver is better than the one in JRX, but no on the MRX. Watch the features on the JBL official site. What Im saying, is that you cant say a driver is better than another, or a woofer is beter than another because it weight's more. Technology gets forward, and each day, drivers and woofers are made with loght weight, and more power.

I did a similar upgrade to my Tapco dual 15" speakers. They had the little stock driver and after blowing a pair of them, I went to the local speaker parts store and picked up a pair of the big Selenium 1" throat drivers similar to what Brian installed in his JBLs. The difference in sound was incredible and I havent blown any drivers nor does the speaker go into shutdown mode after having too much high end going to the horns. All you guys who poopoo changing drivers should use your ears.

The Selenium isn't a shitty after-market driver - it's a good quality brazilian product, clearly superior to the regular chinese stuff. The result could be better if the cross-over were matched to the new driver.
aldonaletto 1 year ago
As someone who has experience building sound systems, and understands most of the science behind it I can't recommend 'going with it' First these drivers are tested in the lab to work with one another. Specifically, the phasing becomes problematic when using other drivers because the non stock driver could be having some cancelation where the frequency overlaps with the woofer. Also, as many users pointed out, these will be rough to stand next to, again JBL tests this type of thing.

You are a complete fuck wit! Why would you replace perfectly good JBL compression drivers with a shitty after-market driver? Those particular drivers are optimized for use with the cross-over & enclosure design, but then again what can we expect when a DJ is fucking around with audio gear!

The Stock JBL Drivers have a "limited frequency response" meaning they are cheap chinese junk. JBL went off-shore for its lower end products. The Selenium are made in Brazil and are a much more superior product. I did the hot-rod and it's awesome! Just look on ebat for the original drivers, they have replacements galore because you blow them out because of how cheap they are. And there are a boatload of used one on there too. So ya think they are any good?? IMHO

WOW Nice Video But U just distroyed a Great Pair of JBL Cabs, From this video, the sound of the stock JBL driver had a BIGGER HF presents, and U can hear it in this video. the new driver u put in the jbl is a good one BUT the JBL driver is a wound ribbon driver that can punch out higher SPL at lower power. Nice way to screw up 40 years of speaker testing and design work.

Brian, I have a pair of JBL SF15 speakers and want to hotrod them. I think they have the same horn as the JRX-115. Since these are 8ohm speaker cabs, do I need a 16ohm driver? I think I saw 8ohm on the driver you installed. Does that drop your ohm load to 4? Please help.. Thanks!
rongrantga 1 year ago
When I saw this I thought, what about the different sensitivity, what about the extra weight and what about the reverse polarity. The reverse polarity causes a huge dip at the cross-over frequency. each speaker is at -3dB and out of phase. But the standard 2412 drivers are a bit harsh. It's not as simple as just changing drivers, you need to pad them down. I bet they squeal like crazy now!!! That's my two cents...
ControlGadgets 1 year ago
In addition to all that has been said wrt to the technical aspect of what Brian did. I would not recommend that the JBL JRX-115 be modified because it was engineered with specifications for optimized performance of each component together. The selenium driver has a larger displacement and therefore would affect the performance of the 15". It may seem insignificant, but am sure JBL would say it is.

the selenium d210ti are discontinued, you'll have to buy the d220ti. the price is about $46.00.

It's was hard for me to believe this was possible but it's true. spend the $46.00 and see for yourself. Don't let some idiot tell you different. also make sure you buy the 8ohm driver not the 16 ohm.

Mediocrebassist 2 years ago 2
On the camera, the sound is easier on the ears with the stock drivers, but I can tell that the stock drivers are much more muffled sounding and the new drivers are hitting proper highs. If I could hear the speakers in real life, it would be like adding the &fmt=18 extension code to a music video, or the difference between good horn loaded and direct tweeters. I have some horn tweeters on my stereo speakers and they are sounding much crisper and I have to set the treble eq lower.

This video has a slight mistake, JBL drivers are positive voltage at red terminal for rearward cone movement, this is opposite to most manufacturers (including selenium). Therefore you should wire the seleniums the opposite way round so it looks as if they'd be out of phase.
chickenfizz 2 years ago 2
One more comment - use Teflon tape (typical plumber's toolbox item - the Home Depot or Ace will have it) when installing screw-on horn drivers. They'll be slightly tougher to screw on, but they'll make a perfect vibration-free seal between the compression driver and the horn throat.
rbuszka 2 years ago
The JBL compression drivers in the JRX are very marginal (to meet a price point; good compression drivers are expensive and difficult to manufacture). Thus, they have a reputation of blowing easily. I recall being at a rock show in a small auditorium in my freshman year with the dual-15" JRXes where one driver went halfway through the show, and the other driver went about 30 minutes before the show ended. The speakers shouldn't have been overworked too badly -- both the woofers were still good.

Hello Brian, very interesting video, but I couldnt identify a good diference of sound in this video quality, but, have you take some measures of diferents drivers to verify a really diference and good flat sound? you must consider a diference in sensitivy of the new driver, it could produce a bad step in dbs with the LF drivers.
Please, if you have more information and tests of it, tell us.

truetone77 2 years ago 2
Yeah, but your missing out on all the frequencies between 12kHz and 20kHz. Humans can hear up to approximately 20kHz so with the new drivers you can hear the music the way it is meant to be heard. Also that warm tone is probably actually distortion from the driver attempting to play those higher frequencies.

bob505470 2 years ago
it is difficult to judge just by wattage, a speakers wattage is actually just a measurment of the amount of power the speaker needs to turn so much electrical energy in to sound energy, there are other much more important figures you need to be looking at when buy pro-audio, such as sensitivity, db spl levels and frequencie response, you only really need to look at the wattage when looking to be an adequate amp. wattage is a measurment of "loudness" , your better looking at db spl levels!
