[QUOTE="helotaxi, post: 1841796, member: 550915"] 15% is inaudible. My point is that a 300w 4 channel amp on an active setup is not going to be as loud as a 300w 2 channel running to the same speakers with a passive network dividing the freqs to them. In the first situation, the mids and the tweets are getting 75W each. In the second, the mids and tweets are getting ~150W each, except above and below the crossover freq respecitvely where the filter begins to act like a resistor in series with the driver and attenuates the signal but at the same time the other driver is wired in parallel and begins getting more power in this freq range and the net result is nearly the same power level all the way across the frequency range. An increase of roughly 100% in power is going to be clearly audible. Even if you only need the 75W from the original active example to get the volume that you want, having the extra power available will add to the quality of the sound by allowing for some headroom and keeping the amp from being taxed and starting to distort.
