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?

Throw a 1,000 wpc x 2 on each side and see if you like it. Buy some old  $300 class D's and see if you are happy. Cost $1,200.
