Thanks Erik. The thing that I’m looking to leverage is the impedance curve with a modest amp powering the high frequencies. I have a NAD 2700 for the low frequencies, with 150 watts per channel into 8 ohms, it’s quite capable. The other amp I have is a NAD 3225PE with 40 watts per channel, an integrated amp with external pre-amp in/out jumpers so i can use just the power amp section. The previous setup had that amp acting as the system preamp and low range bi-amp powering the same speakers, and a 3220i for the highs - that combo worked very nicely. The game changer was finding the 2700 amp for a bargain.
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?
