How many active speakers have you auditioned in your own space?
No one in this thread has claimed that you can't get a great system with either passive or active. Given the SAME budget you will get better performance from an active setup.
"I came up with a way of addressing this question. When people listen to one of my Debut speakers, they don’t ask, “I wonder what this would sound like if you used this SEAS tweeter or that Vifa woofer.” They just accept the choices I’ve made. In an active speaker, I’ve gone one step further in adding another component. But now I have all the benefits of an active design. So [they] just accept them. With passive speakers plus a single amplifier, I couldn’t have achieved that performance at that price.
Each amplifier is matched to the driver, and only has to operate over a limited frequency range. It’s operating into a simpler impedance, so it’s not going to have high-current demands. Also, the temporal characteristics of music change with frequency. High frequencies require very little average power, but have a lot of peaks. Bass requires much higher average power, but has far fewer peaks. You can match the amplifier to those characteristics as well."
