I've read a little about what relative amplifier power ratings should be between different bands of an active speaker system, but wanted a little clarification from people with experience. I'm building a 4-way speaker with 500 WPC of class d power for the subs which are going to operate up to about 100hz, then most likely anywhere from 20-40WPC for the remaining bands which will be a PA mid bass operating from approx. 100hz - 300hz, "full range driver" operating from about 300 hz to 6khz and a tweeter from about 6khz on up. My dilemma comes from deciding power ratings for the amplifier. Im designing the amp myself and want to keep the necessary power down to keep amp cost down, but my full range will be about 96dB/w where as the tweeter is 88db/2.83v with a 6ohm rating so really about 86db/w. I know in average power the tweeter will never really need much power, but will I need way more peak power with this tweeter since my full range is so much more sensitive just for the tweeter to keep up or will the same amp power rating suffice for the tweeter?
