Ive always built my boxes from mdf but yesterday someone gave me enough 1.5 inch plywood to make a box. Is thick plywood as good as mdf/ I mean I see a lot of people building with plywood these days . 20 years ago my crowd would have laughed at em and poked em with sticks and shit, ya know?

depends on the grade and what fasteners you plan on using. Plywood does not always like screws and can split and of course if it gets wet like most wood it is really done but if it were a good grade I would consider it but it would need to be GOOD......

I would go MDF all the way....

All my boxes are birch ply. They're really solid and light. But that's higher grade ply... not the choppy stuff. But 1.5" thick???

i almost always use 3/4 birch plywood for my boxes now. i have never looked back. mdf is a bit cheaper, but the birch works just fine, and is easier for tnuts to set into, and nicer on my drill bits and saws. its about 1/3 lighter too which is nice

if its good plywood, it will be just fine, probably better then 3/4 mdf.

you guys are talking baltic burch right? that is good stuff as long as you can afford it but I would not really consider that the traditional plywood that most people think of when saying plywood.

I made a box out of 1-1/8" form ply (void free, 11 ply).......... presented well as a sealed SQ sub box, blended nicely with the front stage. If the edge of the 1.5" shows no voids, have at it.

I would also flex it a little bit(as much as you can 1.5") to listen if you can hear it comming apart. Some plywood does not do well with vibrations and can break down after time I have heard.

i'm not sure if its baltic, but its 9 ply for 3/4 inch, and voids in the ply are very few and far between. its generally about $10 more then mdf for a sheet
