Thanks, Kijanki.
One other thing I should mention: I don't intend to give the impression that a low damping factor amp will work with just any speaker. I'd want to see the impedance curve and possibly the frequency response curve before making that call.
That being said, a couple of weeks ago a friend of mine wanted to try a low damping factor amp on his 89 dB, 5-to-20 ohm two-way monitors. I was skeptical because of the impedance curve. He liked the sound, but there was a lower treble emphasis associated with an impedance peak in the crossover region (which I had predicted, having seen the curve). So I calculated and assembled a circuit that smoothed the impedance peak, and that solved the problem. Maybe that would work with other speakers as well. I'd like to adjust the bass tuning in his speakers also, but we haven't gotten to that point yet.
