Box Volume
I have all the equations to construct a box but i am wondering about the volume required for the sum.
When a sub says it requires .66 cu Ft of air space is that air space of the box without the sub installed(ie. no sub displacement)
or do you have to compensate for how much the sub will displace- if the sub displaces .1 cu Ft then should the actual empty be .76 cu Ft.
Thanx

Use MDF not regular plywood. 1/2" is not a good idea, especially if its a 10" sub or bigger. The box could flex or even shatter under high SPL's. Ployfill (pillow stuffing) inside the box about 1/3 full can sometimes make a big difference.
