DIY Building a 2x12 cab

[bure998]

i build my own too..a couple points..i mount my speaks to the outside of the board..better dispersion. i also don't bother to dovetail corners. i use drywall screws and bolster all inside edges with glued1" trim pieces. once your back and soundboard is screwed into place, the box is extremely rigid. i also usually separate my speaks with another piece of plywood leaving 3-4" of space at the front and back, and yes, this cuts down on internal volume but makes the cab really punch. roll your own!!

[MrDimebuck]

where did you get the output jack?

[simonrobb99]

Nice video.I'm gonna make a 4/12 and 2/12 in the future.Anyone got wiring diagrams for a high gain metal amp? Think that's a good project for the future.making my own amp!

[KINGTHEBEAST]

mute!

[thatcoolG]

did you use 18 mm birch ply and if you did what grade?

[darren0512341]

cab's are getting so expensive these days on the market, it's just a wooden box and speakers in it really.

[VerberneNewAge]

What is the output of the cabinet? In terms of watts. i'm keen to make a cab, just bought a 150w head so I thought it'd be cool to make my own

[sreeramk]

@VerberneNewAge Your cab's output is dependent on the speakers you use. I think the combined wattage of my cab was 150.

150watts head means that's the max output. A speaker rated at 80 watts can withstand probably a 100 watt head by itself because the manufacturers will add a safety factor. So, if you get a combined wattage of 150 for your cab, that's more than sufficient to handle your head's output.

[KTM5001]

so im guess do you just connect the speaker to a to a input/output jack to a head so you don't need to connect the cab to the plug in your wall ( sounds a stupid question but i was just wondering)

[sreeramk]

@KTM5001 Not sure what you mean by connect the cab to the plug in your wall. The only thing on the wall is power and that goes to the head and not to the cab. The cab does not need any electricity to work.

[liulululi]

Nice video, thanks. What is the thickness of the plywood in a front and the other pieces?

[sreeramk]

@liulululi Sorry, its a while ago. i think its a standard 3/4" plywood.

[baconbag]

Dinner plates, brilliant. What's the biggest difference between open and closed back cabs? I'm wondering because I want to put vintage 30's in a closed back, but they usually come in open back cabs. thanks

[sreeramk]

@baconbag The difference is mainly in the low-end response and headroom. Closed back cabs like the one I've built have a tight low-end which is great for heavy metal where the tempo is very high and notes are spaced very closely. Open back cabs give a very airy "open" feeling and the notes bloom and sound louder. At the same time, low-end is not tight and might sound flubby. If you're mainly playing clean, its better to have open back or semi-open back.

[baconbag]

@sreeramk Ok thanks. It looks like I will probably go with a closed back.

[mmmben]

Any particular reason to mount the speakers behind the cutouts, as opposed to sitting in them?

[sreeramk]

@mmmben No reason. That's just how the rectifier cabs and most cabs I've seen have speakers placed and i decided to go that way.

[thatcoolG]

can't i just put a horizontal cab vertically will it put to much stress on it? and this sounds soo bassy... :/ is that from tho wood/ speakers or the mic?

[sreeramk]

@thatcoolG No. It will not put too much stress on it. But you'll see that it'll lose some bass by putting it on the side. Wood/speaker/mic/amp, all play a role in how much bassy a combination sounds.

[SymphonyforClassics]

You say the bracing is 1in x 1in x 8ft right? one for the front, the other for the back? It looks like the width is longer than 1in almost. Also I was wondering, when you slide in the piece with the speakers mounted on it. do you cut that to a different dimension so you can fit in inside the cab? because by then the bracing was in.

[awesomelikeapossom]

DEVIN TOWNSEND :D

[isomikieee]

using the head as weight made me lol

[sreeramk]

@isomikieee yeah, I just made use of whatever I had at home at that time. If you want to do it the professional way, you've gotta buy ties and clamps and what not. I did not want to accumulate too much junk in my house for a one time project. LOL.

[cheddarbird]

for the materials, do you mean you have one 4 x 8 plywood cut into all the other pieces, or one 4 x 8 plywood PLUS all the other pieces?

[sreeramk]

@cheddarbird One 4x8 Birch plywood cut into all the other pieces. 

[cheddarbird]

@sreeramk thank you sir

[lmak23]

Hi there great vid! I want to build one my self! I looked at the comments but nothing could you plz tell me how thick is the plywood?? Is it like 18mm??

Thanks!! Thumbs up!!!

[Haiw408]

Rad video bro! Go to Facebook and search Asher Cabs!

[MrPhorick]

@benfirst Devin Townsend does not suck in my opinion he has an amazing singing voice that ranges from mellow to metal judge for yourself look up the song thalamus by strapping young lad (its his other band) and tell me what you think

[benfirst]

The singer sucks, but good video.

[andyscoot43]

@benfirst Devin Townsend is well known for his amazingly versatile voice

[MegaDavetastic]

Super awesome vid very informative.

[MYTUBEISAPUSSY]

how much was each speaker ?

I recomend some pro guitar-eminence for only 75 bucks a piece

outperforming celestions doble the price........

[guitarSSBF]

how much were the speakers

[fabpab]

Hey mate... loved the clip and dev! good choice... Can i ask a question.. what size are your box joints on each side.. 1" ? 1/2" ?

[fabpab]

Im so gana build my own now!! .. ps love the Devin..!!

[lpm742004]

A dish!... Good Idea!

[smickers86]

hey dude, I had a question for you. I'm about to make my own cab as well and I noticed you have 4 of each dimension, however what did you make the rear and baffle out of? and what are the dimensions?

this is a really good build! I'm using the same concept but with the Roadster 212 cab.

if you could hit me back with a little more info that would be sweet!

[corissimo]

Thanks for this video. I want to take my 4x12 and make two 2x12's. I think this is how I'm going to do it. Best

[riotdiscoman]

Great Video! Considering your materials and tools that you had to work with you did one hell of a job. Mesa's generally use a void free Russian birch that is much more dense and expensive. If I am not mistaken they also use a dovetail joint on the corners but the box joint you used is more that sufficient for that application. If you ever get access to a hand router you can route round over corners before tolex.

[rhykko77]

no doubt that form of corner joining will produce a very strong corner, but good screws and glue will produce a corver that will not break even with a butt joint.....the wood will break first .....so , though I respect your skills, that is a lot of work for questionable strength gain

in strenght.

[evilguitar9430]

how much did the speakers cost?

[tokyosan1]

THUMBS UP for the DEVIN TOWNSEND SONG!!

[TheSmyates]

how much were the speakers

[razormusik]

Where did you get the dimensions?

[Wonmanbanned]

Looks great and sounds good, big thumbs up!

[chauloko]

Woah! Amazing stuff man.

What amp are and guitar you using for the clip?

[sreeramk]

@chauloko Thanks! By 'Clip' I presume you're talking about my wanking at the very end of the video. Its was a Jackson DK2M into a Mark IV.  :)

[pissballs]

I like DIY ers they're Inspiring ppl! Better to save the bulk of the cash for something harder to make like the speakers themselves! LOL

Slap some warehouse speakers of your choice and it maximizes the bang for your buck!

[smp156]

you are going to get glue all over someone's very expensive wall-to-wall carpetting

[StupidSpoge]

You're a saint!

I've been looking for the real dimensions for some time. (I don't trust the ones on the site...)

I build an EV TL806 last year. It's a complicated design, but it turned out amazing!

It added so much bass to my 5150, which normally wouldn't have enough! Now there's too much! I need to build a 2x12 to even it out.

[Coonetta]

Nice video. How did you attach the baffle to the unit?

[sreeramk]

@Coonetta For the cab in the video, I secured it using screws from the sides. So, its sort of permanently fixed since I've tolexed the cab since. I realized that at some point, someone might need to take the baffle out for whatever reasons and so for my second cab, I screwed the baffle to the front bracings...the way its supposed to be done. :)

[DiminishedDan18]

Awesome vid dude! Im in the process of doing the same thing. My question is how did you wire your speakers to one input?

[sreeramk]

@DiminishedDan18

Thanks! :) For speakers wiring, connect +ve's and -ve's first and then choose any one speaker's +ve and -ve for the mono jack. Good luck!

[EnvyInc]

@DiminishedDan18 It will depend on the impedance rating of your speakers and the impedance rating of your amplifier's output. You want to match the impedance of the two. Say you have an 8-ohm tap on your amplifier. You'll need either two 16-ohm speakers (wired in parallel) or two 4-ohm speakers (wired in series) to achieve the 8-ohm load you're shooting for. If you have any questions about impedance matching, send me a message.

[PhoenixCrush]

how is the baffle held in place? are there screws on the side or top holding it? also how wide are the box joints?

[sreeramk]

Thanks! Devin townsend. Name of the song is Storm.

[dudeastar]

hey cool vid, who was the band playing.

[DawidHudziak]

I just got inspired to make one:)

thanks for sharing your experience; very helpful

regards

[ricaard]

You forget to mention the dinner plate as a tool! Great job, man! Is that all there is to the cabinet?

[sreeramk]

Cesar, thanks man! The MK IV sounds tight through this cab. Even though they're only warehouse speakers, they sound pretty good. Some day I'll replace them with V30's.

[acejcra]

Cool Vid, great way to save some money.
