View Full Version : How Many Cubes?

07-11-2006, 11:37 PM
Ok I have (2) PA MOFO 15's. I bored so i want to make a box for em and try and sell em. I want this box to get loud...so I'm going to tune to 32 Hz (i want them to them to be loud low monsters). The subs will share a common chamber. they will be inverted and there will be and *** load of bracing. Specs call for 3.4 cubes each but since im going more for SPL what do you think i should do? Also what does adding more air space do...i know i have searched and read a lot but im just looking for some personal answers to help me understand better. thanks, andrew

more net volume will give a flatter response and should result in lower bass.

ok so more net will give a flatter response...but with enought power and the right tuning frequency can they get loud?

also any one know how many cubes the mofo's like?
