[QUOTE="96civ, post: 1994350, member: 564776"] I'm thinking of constructing a 4th order bandpass box for my sub, but I'm ambivalent right now because I do not know the following: what is bandpass ripple, will I see any loudness difference between the ported box I have now (32Hz with 2.5 Net) and a 4th order bandpass I will build with a gain of .4635, I don't know what the cabin gain for my car is, 96 Civic 2Dr, and I'm wondering if I get the box to have a flat response curve will the cabin gain make it sound like crap, and do you think a low 3dB rolloff at 30Hz and a high 3dB rolloff at 71Hz will sound decent?
