Sure lot's of audiophiles do that. Only if each loudspeaker has four terminals. The two problems are matching woofer & tweeter levels and polarity.
We often use our DVA 4/2 amplifier for this purpose. It can do either four independent channels or two very high power channels.We simply use all four channels to bi-amp speakers with separate top and bottom speaker terminals. Two channels of the amplifier per speaker.Make sure you remove the links between the top and bottom speaker terminals before trying this!It does make an obvious difference in overall system performance and since the four channels are identical, no gain matching is required.Frank
This is possible as long as the speakers have separate terminals for the tweeter and the bass / mid range.I have done this in the past but only using 2 identical stereo power amps. I did this years ago when I had Roksan L2.5 pre and 2 x S1.5 stereo power amps, it worked nicely I got cleaner more refined sound. What you are proposing doing is completely different type of amps, sounds you like you may have problems first you will need to find different amps with the same gain. Also if one amp is slow and the other fast, I don’t know how that will play out. Example my Spectral is very fast if that is what is called for, I can’t imagine how the sound would be if I pair it up was say a slow amp driving the tweeters. I guess only one way to find out, give it a try.
A coupling capacitor does not rotate the phase. But a cross-over cap does.
For all practical purposes, all amp have the same thru-put speed.
What differences you heard were not amplifier speed in any engineering meaning of the word.* * * * * * * * *Audiophiles have been mating solid state and tube amps together for decades without this 'speed' problem.

I think TooCool is talking about rise time. Many use this non scientific term, being knowledgeable in other fields.Yes, TooCool, the ear perceives rise time differences of at least 5 us (microseconds), some claiming as low as 2 us.cheerssteve
