View Full Version : Need Help With Bandpass

05-26-2008, 10:33 AM
I have 4 MA Audio 150QS subs I'm planning on putting in an '01 Blazer. I'd like to know if anyone can tell me whether or not they'd work in maybe a 3 chamber 4th order bandpass and how large of an enclosure I'd have to build to house them. They recommend a ported box 3.75 cubic feet tuned to 40hz, and if I have to build something that big I'd have to put a wall behind the rear seat with the subs and ports facing forward, so I'm worried about overall sound quality. Any help would be appreciated, ty.

The specs on the subs are as follows:
Fs - 23.03
QMS - 5.62
QES - 0.51
QTS - 0.47
VAS (Liters) - 297.84
REVC - 3.2
SPL - 90.35
Xmax - 14mm
LEVC - 2.523
