    Simple Question

    I have 2 15L7 D4s and I will be putting them in a sealed box.

    Kicker lists the enclosure volume for the 15 as follows:

    Min 1.5 cuft.
    Max 6 cuft.

    My box will give them 4.4 cuft. per sub.

    What sound/performance difference will there be with 4.4 compared to 1.5 and 6? I can't seem to find this info anywhere. Will they be louder with 4.4 instead of 1.5? Will they hit lower, etc?

    IDK much about L7s but I do know that they aren't the best in sealed boxes.

    Re: Simple Question

    Well here is what I got from a QTC calculator. I'm not sure what it all means but maybe you guys will be able to tell me.

    Qts = .507
    Vas = 5.2 (ft3)
    Fs Hertz = 26.3
    Vb (ft3) = 4.4
    Qtc = .7489
    Fc = 38.85 Hertz
    F3 = 36.8 Hertz

    Does that mean that the box/sub will perform the best at around 37 Hz? LOL this stuff is confusing to me.

    Re: Simple Question

    Here is what I have in my current setup with my PG rsd12d subs. Maybe I need to move this to the subwoofer section to get a little more traffic. This section is SLOW.

    Qts = .55
    Vas = 3.39 ft3
    Fs = 22.4 Hz
    Vb = 1.9 ft3
    Qtc = .9177
    Fc = 37.38 Hz
    F3 - 30.66 Hz

    F3=recommended tuning frequency, but since you are going sealed it doesn't apply to you.
