[QUOTE="hispls, post: 8307086, member: 614752"] I'd be trying to do ANY SIDE wider than a couple feet with 3 layers of 3/4 ply plus some bracing where possible. From where you're sitting, it looks like space isn't really an issue, and the cost of adding a few more sheets of 3/4 is really negligible. It'll be a whole lot easier to do it now than to find walls flexing later and try to Band-Aid with bracing. I think that the baffle will be OK with that window-pane of 2X8 but 2 layers plus some really thin sheet metal is pretty dicey with such large walls. I will never forget building a box with 2 layers of 3/4 MDF in 1996 for 6 12" JBL subs (pretty entry level at the time). On about 800W total the 1.5" MDF was flapping around visibly People, I think, grossly underestimate how much pressure a box with this much cone area will build up even without a lot of power.
