Re: QSC GX3 - Is it enough for my horns?
With a clipped music signal, the diaphragm is moving at all times.
Even with a 10KHz square wave the diaphragm moves 10,000 times a second, as opposed to DC, where it is held in place.
An actual square wave will have 3 dB more average power than a sine wave, and a sine wave a lot more average level than music.
Bennett wrote in post 23:
"If this were true, then any time someone played a square wave keyboard synth the PA would catch on fire."
Bennett is ignoring the fact that if someone played a square wave with an equal peak magnitude of any normal music transient, the average power delivered would be an order of magnitude higher than usual music.
Bass speakers sometimes do catch on fire with full tilt boogie square waves, but HF drivers voice coils generally melt through too quick to catch fire.
So you are both wrong, glad to help :^).
