It doesn’t sound like you are getting advice from anyone who has tried bi- amping. I have. First-You just need to try it and see if it sounds good to you. No rules will help guide you in my opinion. I use two Bedini class A amps to bi-amp. The 25 watt is used for mids and tweeters. The 100 watt is used for woofers. These are excellent sounding amps individually. Bi-amped gives an amazing improvement. I’ve used them successfully with passive and active crossovers. Fire up the amps you were thinking of using. You can’t hurt anything if you don’t drive the speakers into distortion.
What’s the Right Power Amp Ratio For Bi-Amping?
Is there a “golden rule” or rule of thumb when selecting amplifier power in a bi-amp setup? It seems to me that the power should be apportioned according to the demands. Since most of the energy consumption in sound reproduction is by lows, it stands to reason I should use a much more powerful amplifier for lows than highs, but what ratio of power? 2:1? 10:1? Is there a wrong answer?
