Bi-amping

Kraft,

That's a great idea you made. They might consider an amp with a volume control on the upper amp so they can level match the powers.

Assuming a speaker is set up for proper bi- wiring / amping, & all other things being equal, I would think a speaker would have the potential to sound much more dynamic & clear @ louder volumes with the increase in available power. To move & control & big woofer takes so much more power than a midrange or tweeter. It has a much bigger motor & requires much more current. The distortion levels should remain much lower when the speaker is pushed hard. 

This will answer your question.
 

I tried Bi-Wire, Bi-Amping years ago and Bi-Wire only made a small difference, but Bi-Amping with a better crossover (I used an old tube ARC two way) made a wonderful difference.

YRMV.
