I appreciate the straight answers, Anthony. I think this is the first time any of us have gotten a decent answer about the HK system.
I grasp what you are saying about the crossovers and power ratings - I'm aware that the impedance and inductance of a given circuit changes depending on the frequency fed to it.

I had no idea the amp was such a complicated setup. I'm not too into such things. I'd prefer a nice standard 6 channel active setup: 4 high pass and 2 sub channels. Each of the four corners can be further divided by a 2nd order passive crossover if necessary. When you go into micromanagement of your speakers through active crossovers it just puts too many holes in the sound, IMHO.

Thanks for filling me in on the DSP switch. I'm going to have to find something to hook up to that switch, like a Fosgate Gavotte, if I can find one.


: The issue here is that the H-K amplifier has 10 separate "mono" amplifiiers and each amp has an electronic crossover network diving the audio bandwidth. Some channels for bass; some tweeters and some mids. While it is true that that each individual amp (inside the one amp-box) has an IC rating of 25 watts, by time the crossover filters out certain frequencies, like bass for the tweeter drivers, the energy gets reduced. This is to say that the tweeters, mids and subs get varying amounts of energy at a given time due to the filtering and crossover slopes. This is how a crossover works. It gets even more involved but I will not get into it at this point.
