Home Amp/Preamp Asylum

Looking for a new Amp or Preamp? If you're after tubes, post over here.

Re: There is some truth to both statements

The amp that just drives the high (or low) half of the speaker sees the whole signal but how much does that matter?

Assuming that neither the highs nor the lows run full range, I presume that the impedance of each gets quite high as you get well past the crossover frequency. If, for example, the impedance of the tweeter is roughly 8 ohms within its operating range, then it's not hard to imagine the impedance being a large number by the time you get to 3 or 4 octaves from the crossover point.

Presumably little power or current would be drawn by the amp at frquencies well beyond the crossover point. This would of course not eliminate any distortion that results from hitting the output voltage limits of the amp but seems likely to help a lot if you are approaching the amps current limits.

I know that you understand this far better than I do and I look forward to your response.
