Is plywood good.

no. medium density fiberboard, aka mdf

not a very good one...

If you would like it to fall apart, it is a great idea. //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

Home Depot carries MDF.

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.

just go into home depot and you should be fine mang...

most fine lumber yards should sell it

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. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

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. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Would that $15~$18/sheet be better applied buying MDF? Yep. Sure would. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Let us know when it's done, post pics, let us know how those pioneers sound.
