When sending 90w to a passive component set, the mid gets 90 and the tweeter gets 90. Each driver is already getting 90w within it's frequency range. It does not divide the power into the two drivers.
If he Bi amps each driver is still getting 90w. I do not see how it would get more power. IF I am wrong, please enlighten me. It would not be the first time I have been wrong. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
