I have an SLA Pro and a T24 as a mono stack in my garage and it's as loud as I want.....and there's more there if I needed it. If you want stereo, a pair of short SLA Pros with a corner-loaded T24 would be a nice combo for a garage.
I bet that's a nice combination. I forgot to post what I've currently got...it's an overnight sensation and an anarchy tapped horn in a little stack.

Yesterday I took one of my SLAs out to the garage and set it on the sub, as much as I like the overnight sensations, the little guys were blown away by the SLA. So I bet your SLA pro/T24 stack is just great for the garage :)

So, if one of those designed calls out to you, there is a budget driver option available.

GRS 10PT-8 $30
GRS 12PT-8 $50
GRS 15PT-8 $60
I had decided to go small table tuba but after seeing this....T30! My decision now is....super sweet and $$$ baltic birch or el cheapo sheathing.

Thanks!! And if you have any budget choices for a top I'd love to hear about 'em

I've used both and would use either again. BB is the standard recommendation and it is nice to work with. But, depending on the specific project, sometimes availability, cost, and/or weight savings make 5 ply pine sheathing the more attractive option. Really, up to you. I look forward to watching this come together, whatever you choose :thumbsup:

Was there something about blond wood not being strong enough somewhere?

Ok, if we're gonna do this I guess baltic birch it is! Now it looks like if we get true, square 60"X60" sheets and we don't include the kerf in our calculations that you can get a 16" T30 out of 1 1/2 sheets with close to zero waste. Does anybody know offhand if that sounds right?

errr you have to include kerf in your cutlist, or you end up short of material. So just call it two x 5' x 5' sheets, and then count your blessings when you suddenly realise one of your cuts was out, and you still have a half sheet to play with,
Keep doing that for all the builds, and suddenly you have a full sheet left over for another project.

If BB is hard to find near you, then anything that is 1/2" and a minimum of 5 equal thickness plies is fine to build with.
You will rarley see me type this, as I hate the stuff, but if your build is absolutely positively going to stay in the garage, you could even build with MDF.

If you're going to cart it out to the ocassional party though, go ply...

A 16" cab uses 15" wide panels, so that buys you a little kerf room, but dont forget about your braces too. I'd say one t30 is close to 2 sheets.

Accounting for and including a 1/8" kerf, it will take 3 sheets if you stay 100% dimensionally true to the plans.

However, if you make your sides 30 by 29 and 15/16" (instead of 30x30), you can get it done on 2 sheets and still have material left for bracing.

Dimensionally true to the plans cut sheets...

If you did the sides 30x29.9375 (15/16), you could go as wide as 16 and 5/8 inches total cab width and still keep it on two sheets. It looks like there's still plenty left over for bracing too.
Adding just one more eighth inch to the total cab width, bringing it to 16 and 3/4 inches wide, makes it a 3 sheet cab. So, 16 and 5/8 inches is just about the maximum total cab width to keep it down to a two sheet build with the modified side dimensions.

I used the free version of MaxCut to produce these cut sheets. There seems to be a slight glitch in the decimal translation of eighths and sixteenths, putting a 2 or 4 on the end where there should be a 0 or 5... but, whatever. Not like you're going to be able to get accurate cuts down to the ten thousandth anyway. :roll:

Oh yeah, the braces, I totally forgot about those. Ha!

Good effort on your part Seth.
You missed the two sheet solution that leaves you with ample to spare for braces, and the correct size panels though.

Go back to your first attempt.
Instead of having having panels 8 and 12 on sheet one, move those panels sideways and below the side on sheet two.
The space you just created on sheet one is now the available for the other side and drops the sheet count by one...

That would be a great solution... if there was enough room below the side on sheet 2 for panels 8 and 12, in any orientation.

After the full size side is removed, there's only 29 and 7/8 inches left below it to fit 30 and 1/8 inches of panels and kerf. One quarter inch short of material to have that work.

The software automattically sorts the parts onto the sheets. It's not something I can manually manipulate. I was really hoping you had outsmarted the algorithm. But, I'm fairly certain the side dimensions have to be modified in order to make this a 2 sheet build.

It may be possible to shorten the length of panels 8 and 12 instead of the sides, since they're oversize anyway, and vertically position them where you suggest. That may produce the desired outcome, maintaining all critical dimensions and limiting the build to 2 sheets.

I don't think I'd have considered that particular solution had you not posted your potential solution. Love the teamwork :thumbsup:

I'll change those dimensions and post the outcome when I get home later this evening.

^Bother.
That all came about because I thought there was saw kerf accounted for at the bottom of the side on sheet 2.
Still, if it means you may come up with a solution, it may well turn out for the best yet.

I use the delphi cutlist (if I do a cutlist at all, I have found over time that relying on instinct works more often than not once using a cutlist has trained your brain) http://delphiforfun.org/Programs/CutList.htm
It lets you do a manual solution as well as auto, and some times you can jiggle things around with better success than the auto comes up with...

I see you are using a narrow kerf blade in your calculations, 1/16th inch.
