'88 RCLB C3500 "Roscoe P. Coltrane"

[df2x4]

If I port the box I can go smaller, right?

IIRC it's the opposite, ported enclosures are usually larger.

Does the sub have a model number or anything you could use to look up exact specs? If so you could input them into WinISD and play with enclosure design in there.

EDIT - A little more explanation... WinISD is free subwoofer enclosure modeling software that can take specific parameters of whatever drivers you're using and let you play with all kinds of stuff, including tuning frequency and ports. It'll even give you a graph of estimated frequency response of the modeled enclosure/drivers. The parameters for your Infinity sub might already be in the software, they have a ton of drivers on file already.

I brought it in out of the garage and pulled it out of the old box. It's an Infinity Reference, not a Kappa, model# 1232W. Looking at the manual (link below), it looks like a completely sealed 1.25 cu/ft box might be a good target, but if you can run it in software and make a better recommendation, I'm all ears!

I think this is based on my setup.

Sorry, but no. It was this pic that inspired me:

Impressive.

Hey, is that your 'Vette driving around on COTA?

Yes it is.

Thanks! It's actually pretty easy if you already have the interior torn down. Just throw the pieces in front of the pressure washer, scrub them, and shoot them. Do a couple pieces at a time and after a couple weeks the entire interior's done.

I bought a $36 4x8 sheet of 23/32 plywood. Sure, cabinet-grade birch might be "preferred", but that's >$80 a sheet, and my carpentry isn't that good. This is probably the best wood work I've ever done. I'm pretty sure it'll sound nice enough for my ears.

The front face is just resting in place; I need to trim it down so that it fits between the top and bottom panel. I measured wrong on the end caps and middle pieces. The end caps are going to get unscrewed and moved into the middle, and I'll cut new end caps that fit flush with the front of the cabinet.

None of it is glued yet, but I'll put wood glue in the seams before it gets final-assembled. I was considering some Tekton 77 for coating it once it's finished, but I think it's large enough I'd need two coats, and that's $90! Anybody have a better cheap idea for painting it? Or should I just stain and varnish it?

Looks good. Don't be afraid to add a few braces inside there. Maybe one on each side of the hole, ties the back to the front, keeps the box from flexing.
