    4th order bandpass an fi q 12?

    i just put my fi q 12 in a 4th order its measure exactly 2.5 sealed and the ported chamber is 4.32 tuned at roughly 55.86 hz you think this will be to big or perhaps tuned to high?

    Ive heard a bunch of 12s in a bandpass that has these specs:

    1 cube sealed
    1.25 ported
    25 sq in of port
    port = 16.75" long

    It sounds good and gets pretty **** low. Drops real low. Worked great for every sub/car combo ive heard it in.

    thats way to big for that sub... it would be hard to do a bandpass without the sub specs but ur prolly lookin at 1.25 sealed and 1.75 or so ported at around 62hz
