Is plywood a good type of wood to construct a sealed box for 2 12" subs?

So can I just get this at any lumber yard? Along with woodglue and screws?

Plywood will flex under pressure, go with the .75" MDF or if your lumber yard doesnt carry it use High Density Particle Board

No, lumberyards are completely against screws and glue. They feel it's harmful and heartless to ever harm the wood with glue and screws. I highly doubt they would carry products like that.

Lot of wacky info in this thread.

 

True void-free, cabinet grade 3/4" ply is excellent material for speaker enclosures. However, at $45 a sheet it's more than double what MDF costs. So it's a value question, not a structural one. But if you properly brace the enclosure, baltic birch or similar furniture grade plywood is primo stuff - if you afford the price tag.

Agreed. :)

 

However, you'll find the majority of perfectly acceptable quality enclosures are built out of MDF. Dollar for dollar it makes a much better box than comparably priced plywood. Can you use normal, everyday CDX-grade ply? Yep. You sure can. :) Would that $15~$18/sheet be better applied buying MDF? Yep. Sure would. :)

alright, well my grandpa is helping me with the project, he is more experienced with wood working. He told me 1/4-1/2 inch plywood (most likely ill be getting 1/2), finished on both sides. and to get 6 two-by-twos that are 6 or 8 feet long to brace the box.. and of course, wood glue and screws... Im not really sure on what he plans on doing with the two-by-twos. SO you guys think I will be safe?

2x2's would likely be for bracing.

 

I'd just save your money and go for the the 3/4" MDF and be done with it.

 

'Good-on-both-sides' furniture grade plywood isn't cheap at all.

He may be an expirenced woodworker and your lucky he's helping you, however I don't know if he fully understands how much pressure is inside of a sub box at times, I know my grandpa wouldn't, but maybe he does, no clue. go 3/4 inch.

Interesting story.

I met a guy who had a dual 10" enclosure built entirely out of chromed diamond plate sheet metal welded together, it looked awsome but sounded awful, nasty resonance.

Thats a little off topic dont you think? I will call him tommorow and ask him about the MDF..so if i get mdf....I need 3/4"? How much does that usually run? And, I asked this earlier but I didnt get a clear answer...Does a lumberyard carry mdf?

#1- call your local lumberyard for that answer, it's most likely in the phone book under lumber yards or building supplies

 

#2- Sheet of MDF is typically around $20 give or take a few dollars
