Sealed Box 15Q

[Jacob86 0]

I want to build a sealed box 25X15X17 for a Q15 is that big enough? Should I add any bracing, if so where

Thanks Jacob

Are those outside or inside dimensions?

Assuming outside dimensions, and 3/4" material, I'm getting around 2.8 cubic feet...which is slightly more than Fi recommends, which would lower power handling but provide a smoother sound, IMO. Or if you added bracing, that could take up the extra space. You'd want to brace perpendicular to the open panels...
