    Default Question about airspace?

    I am building a custom wedge box for my two mm100's. I've been told by a couple of box builder's to only have 1feet^3 of airspace. Yet, shouldn't it be .62*2=1.24feet^3?

    Also, I've been planning on doing it without a divider because I will be running them bridged. Is this ok?

    Thanx for all the help

    To get the best possible performance build a 2 chamber enclosure that has a sealed volume of .66 for each chamber. If you plan on building a common chamber for both woofers, then the recommended volume is 1.0 cubic feet. Install 3/4 to 1 pound
    of polyfill in the enclosure, and allow 40 hours of playing music at a reasonable level to let the driver's suspension "break in".
    A good crossover frequency for these woofers is 80 to 90 Hertz.
    Just make sure that the amplifier is capable of driving a 2 Ohm bridged mono load. The recommended power for these woofers is between 400 to 800 Watts.

    Happy Bassing!!
