    Re: Tuning a Bandpass?

    um to be honest with u.......your best bet is to throw away that box......from the desription of that box i knew right away its a pre-fab...and it will not sound good even if u put a 500dollar 10inch speaker in there.....why dont u just get a bandpass box custom build to the speakers specs and then we can talk about tuning

    Sounds like a prefab bandpass like they sell at best buy, which is totally worthless.

    Bandpass boxes need to be totally custom designed.

    3 Sides: 11.5 x 31.5
    Baffle Location: 7 (mount speakers on this baffle)x 3.75 in

    Vent Parts
    4 inch round port 8inches long tuned @45hz...if u want it tuned lower get a long 4inch pvc pipe and the longest u can make the port is 28inches and the tuning freq. and that lenght is 29.9hz....so its up 2 ..

    the subs will be in a common chamber of 1.4cuft(the port will be in this chamber)
    and the sealed will be .727cuft
