List of parts to build a speaker box

Polyfill can have some effect on dampening standing waves inside an enclosure, yes.  Lining the walls (or at least the back wall) with genuine acoustic insulating foam (like this or an equivalent) is actually a much more effective solution for correcting standing wave problems.

I just build a sealed slant box for my Honda. It took the better part of a day. But I am a drafter, so I drew it in AutoCAD first, so it was easy to figure the angles. As for tools, I found that the circle jig for a Rota Zip works excellent for the speaker cutouts

as far as glue goes... the best stuff is construciton grade polyurithane (i think thats how you spell it?) This stuff is twice as strong as liquid nails .. and it has tensile strength..

you get the stuff at home depot... it comes in a yellow and brown bottle... and i talked to the glue guy there and he says great stuff about it... but use gloves , because its hella hard to get off youre hands, but i swear by it...
