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 ?

'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!

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.

Out of phase is gonna kill the output...

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

Careful, by those definitions Spider Monkey is a contributing member, I don't think he even knows what a subwoofer is.

 

Thanks quackhead. Your the only person who agrees with me. Jesus Christ I have like 40 post and I've been called a ******* like 37 times

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.


Saying "clipping doesn't kill speakers" is a half-truth at best. Technically no, clipping itself does not hurt the speaker. But in clipping your amp, you can easily create a situation that WILL kill the speaker. Was the squared waveform the DIRECT cause of the failure? 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.

Not worried about load 5 single 4 ohm alpines just wanting to see what I can get done with some cheapies only giving like 300 a piece if that from a mb quarts 1500.1 just was worried about placement but I can go wider if I want... Going in a dodge ram 1500 quad cab with no rear seats...

Thanks got the bug again and it's warming up now too... Much nicer to work on this stuff when it's warm out

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

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:
