Why You Shouldnt Play Vocals Through A Sub

[Boon]

the technical reason , is the voice coil acts as a natural cross over, the voice coil is an inductor, just like in a passive cross over, they are rated not just in Ohms, but in Milihenries, the higher the number in mH, the lower the frequency response

and the weight of the cone is another factor, but even if the weight of the cone was 1 gram, it will still have that natural 6db slope, or whatever it is

but the coil, and the MMS kind of work together on this, in there own ways

Ahh yes, how the hell did I forget this

playing higher notes to a subwoofer will not cause any damage...like forevrbumpn said...the inductance of the coil is why it doesn't really matter

Actually aznboi3644, yes it will, under certain set conditions. The car audio environment may not be suspect to these conditions frequently, however it certainly is present. As mentioned before, the coil assembly is not cooling itself down though there is power present in the coil, thus producing heat. Again, in the car audio environment when your mains amplifiers are not quite as powerful as some, this issue is not quite as pressing.

It is common knowledge however in the sound reinforcement area that crossovers too high on your low frequency drivers can and will cook them. When you are juggling 3k a side and you are putting in 3k of real world wattage into a motor that isn't cooling, you won't be making any noise for a while.

Also, a lot of it is psychoacoustic. You don't get the results you want in terms of pressure as the driver cannot reproduce these frequencies, so you turn it up. More power to the coil but no real gain in terms of volume. So up it goes some more and more and more until you have breached the specific thermal capacity of that set motor and whoosh, now you have a slinky.

tl;dr Don't do it. You are putting high power high frequencies into a driver designed to cool through motion and it just ain't moving.

And cheers to Boon. I run a pair of P.Audio 15" midrange drivers to 1.9khz.

Cheers,
