    Subwoofer cancellation ?

    Ok this might be a very stupid question...

    I have 5 12 in subwoofers and 58ins across the front of my box i cant put all 5 on the front...

    I was thinking of firing 4 forward and 1 up would this hurt anything ?

    Re: Subwoofer cancellation ?

    'Hurt' anything, not likely - so long as your amp is able to handle whatever impedance load it would put you at.
    Your probably not going to get much performance added from that fifth woofer (firing up) versus the four firing forward though.

    Is there a reason you'd want to use all 5?

    You can fit them, you could have three facing forward with the other two angled. It could look pretty nice, impedance would be my concern also!

    Or stagger them if you have the height.

    3 facing one side, the other 2 facing opposite side and wired out of phase.



    All day I'm clippin'
    voltage be dippin'
    I don't give a damn,
    cause my trunk always hittin'!

    creating a proper sound wave. Step one, turn it up until clipping. Step two, done.

    Is there any surface of the enclosure that you could fit them all?

    Re: Subwoofer cancellation ?

    You will be fine to put one facing up. It won't look very good but you will not have major phase issues and it could possibly smooth out response.

No. In the end, the answer is, always has been, and can only be... heat kills speakers. BUT, clipping increases heat generation, sometimes by a drastic amount. So to start a thread simply to state that clipping does not hurt speakers is, again, a half-truth at best.

    I thought the out of phase sub will reinforce the sound waves being produced by the other sub? kind of like a passive radiator???

    Re: Subwoofer cancellation ?

    Passive radiators will at best resonate 270 degress out of phase of the woofers (at tuning), reinforcing the woofer output (like a port).
    Out of phase woofers will fire 180 degress out of phase regardless of frequency, causing cancellation across the spectrum.

    Some good info on PR's over here:
