how to biamp with different amps?


I have a pair of Paradigm Studio 60.2 that I want to biamp with 2 different B&K amps. I want to use a ST-3140 to power the woofers on my main speakers and a ST-140 to power the tweeters. So I will have 140 wpc going to woofers and 70 wpc going to the tweeters. I am using a Denon AVR 3802 as my preamp/processor. Will I need an additional crossover? Do I just run an IC from the reciever to one amp and then a connector between the two amps? If I do this, will each speaker be capable of 210 total watts per channel?

You need a crossover between the preamp and your amps, such as Bryston, or Marchand. Because your amps are different you will want a crossover with adjustable gains for each amp, unless your amps have integrated volume controls on them.

Yes, you add the rating of each amp together to get how much power you are capable of feeding to your speakers. It will actually seem like more though because your amps will not be wasting power on portions of the signal that would get cancelled by the crossover.
