    well what ive been told, is that a bandpass covers a VERY small frequency range. if you don't have a deticated midbass or something, that you will be missing out on a lot of the music.

    Re: unusual sub box desighn help/advice pleze

    4th order bandpass
    will beat but serriously lacking on the SQ end
    from the lookes of your design you have there, with the front chamber beeing so big it is going to narrow the response a ton,
    the response will be about 30-60 hz nothing lower and nuthing higher,
    it would raise the sensitivity up alot ya, but the way that box is setup up it would be strictly SPL but at the same time i really dont think a box like that is going to have much cabin gain the way it is set up

    for example a type r 10 in that box, with the back chamber the sub is sealed in we'll say is 1 cubic foot, and the front chamber with the ports is 2 cubic foot
    if you tuned it like a ported box at we'll say 36 hz it is going to pick up 27hz through 47 hz like a dream, but almost nuthing below or higher therefore make the SQ on the box absoultely terrible

    try it if you want , but you will more than likely be dissopointed with the end result
