Just finished building this for a coworker. It's sporting 2 3015's. I couldn't talk him into duratex for the whole cab so I duratex-ed the baffle and carpeted the outside.

Nice solid-looking cab, I'd like to pick your brain a bit. Is this your first use of 3015 drivers? Can you share the inner/outer dimensions? Port dimensions? How much does it weigh? Is that a single grill for both drivers? I've currently got two 3015-loaded TL606-type cabs, might just be better off with something like you built.
Beautiful, I wish someone close to me could build like this. Thinking of tackling a pair of very similar 2x15's myself in the next coming months and I will be coming back for reference surely.
Nice.freakin.work.
I'd like to thank you for doing this, and reinforcing my assertions that the 3015-loaded 2x15 is a kickass rig.

Nice pro looking job. Do share sizes/tunings, etc. My only suggestion ( don't consider this nitpicking ) but maybe take a cheap can of flat black spraypaint and blacken in the foam that's visible through the port.....or not if he likes it that way.
It really does look like something you could put a logo and a pricetag on.....good job.

Thanks for the compliments!
Weight is right at 70 lbs. It turned out heavier than I expected, but I didn't hold back when it came to bracing.
I doubled up the 1/2" ply around the baffle so that the baffles can lay against it from behind when assembling. Just something I thought would work well and it did.
The vb for the box is 6.5 cu ft. The fb is 45 Hz. I like an 18x22 inch footprint so that's what I went with. Not too big to fit through doors, but not too small visually either.
Will33, the foam isn't visible under normal conditions--in fact all you can really see through the grill is the silver frames of the drivers--but the camera picks it up. Here's a picture with just the light from the room:
Koobie, it is a single grill, 3/16" holes, 3/4 bend on all four sides.

Seventy pounds for a dual 15 still seems like a pretty reasonable weight to me. My two TL606-type cabs weigh about 55 pounds each. Between that beefy handle and the skid bars it wouldn't be too hard to move around.
For next time, you could probably shave a few pounds and achieve slightly better performance by putting the port all at the bottom.
I'm curious, how so?
Small world! That design looks incredily familliar! if by any chance the baffles are around 30mm from the front edge of the grill, I have a sneaking suspicion I've just spent a week building one too!
Me and a friend of mine run a PA hire company in Chester (UK), and wanted something for the low-end of a 3-way drum monitor. We foamed the inside of the grill, and held it in place with the batterns you can see in a [ ][ ] shape. then from the sides of the cab we drilled through and through the batterns to hold them in lace. now if we need to do maintenence on the drivers we can get behind the grill without having to wrestle with creasing the foam!

If he put the shelf on the bottom he'd only need one. So you shave a 6" by 20" piece of ply or so. At least, it *looks* like he's got two shelf pieces there, and to my understanding you have to have them to make the tuning work properly
70ish pounds is way acceptable and nothing to be ashamed of; you did good.
My AMPEG SVT-215's are like 125-130# noticably lighter than the 810's but still quite heavier than your project.
Yes I agree the deeper footprint is the way to go. I have built a lot of 215's and have used the 36"X24" size range if you don't mind a little depth. Round ports can save weight.
That size and the extra depth really helps when stacking up 4 cabs stability wise. It also helps with road cases fitting vertically inside vans, where a fridge won't stand up in a case. There's a lot of things to consider.
The old days with fender sized cabs being only a foot thick you could get one hand on a bassman or showman cab and carry it; they were around 70# I suppose too. Those days I'd put one in each hand...
