6 layer cabniet grade plywood for box?

Recommended Posts

I was at my local homedepot ( on military highway for the locals guys) and they have 23/32 cabinet grade plywood for $29 a sheet. I was wondering if it can be used to build a sub box. It is either that or traditional mdf. It just looks like a good deal I can't find the 13 ply Baltic birch everyone talks about so I was hoping I could use it. My box will be 2 layer thick if that matters. Thanks for the help.-Jon

I think Starr Mountain on the forum uses a cabinet grade ply to build boxes, not sure on the details though.

Ok thank you for the input I'm gonna keep on researching. Anyone in the Hampton roads area know where to buy the right wood other then mdf? Nothing against mdf I'm just trying to save a little weight.

Home Depot and Lowes usually have 7ply and 11ply. The 11ply is MUCH denser and better to work with. The 7ply will work, but the layers are thicker/softer, so it's not as strong.

I think I might just buy a sheet and do a small build to trying it out before I go all out with my real build.

what is the big build? How large of an enclosure? If panels are really big you can always do window bracing or strap bracing for smaller enclosures

The big build is 3 15 XFLs on 4k. I'm not sure how big the box is because I'm waiting on a design. Probably 12-15 cubes I'm guessing. I will definitely be bracing it really good.

Cabinet grade just means that the outer plys are clear without blemishes. Inside there can still be voids with 7 ply but if you're doubling it up and bracing it I'd say it's OK.
