ahh thats what i thought you meant, i might try it i might now, depends how creative i feel when i build the box the subs are 175rms each 3 of them, do you think the box will have flex to it at all? should i just try to do it all in 1", double baffle, or just brace it, or it will be fine with 3/4 mdf on its own? the box isnt going to be that big.

 

3/4" will be fine, it will still need to be braced in-between the woofers.......

 

30" W
13" D
12.5" H

~ 2 cubic feet after woofer displacement
3/4" MDF no internal bracing

 

thanks jalat, i was thinking about doing one of these, H=13, W=34, d=11 = 2.05cf or H=12, W=34, D=10 = 1.67cf, the 2nd is closer to .5 each (recommended)
