Hi: Back in the Nineties; I used a Bi-Amp set up. I was using some Adcom stuff the GFP565 as it has three sets of out puts. I used a GFA 535 with about 60watts/Channel. So, When I bought some Polk Audio SDA SRS 2.2 speakers, I needed a bigger amp! I stumbled into a Great deal on a Bryston 4B they were rated at 200watts/ channel then. Even then I was aware of Polk tweeters blowing fairly easy with too much power. My previous speakers were DCM Time Windows (first series). What I did was put the 4B into the "Bass" end of the Polks;(6x 6 1/2 mid woofers into a 15" sub bass radiator each speaker), then used the GFA 535 to run the tweeters and the Time Windows. I never blew any tweeters! That set up had 10; yes ten tweeters. The bonus was the best Holographic stereo soundstage I have ever had or heard. I had the DCMs on the side walls 6-8 feet from the Polks and Image at about 270 degrees in front of me. My case was I got new gear and did not want to part with the old gear yet? Once you know a sonic signature in your set up you can use that to get "other" results. When I played Jimi Hendrix's "Purple Haze" he sounded outside the window singing in and between the two right speakers. I told people this and when I played it they were amazed? I guess what I am getting at is A lot of previous people are right on " Bi Amping Blues". I wanted to experiment. Out of fear of blowing tweeters and having Extra Gear, so I Bi Amped for fun, and got an extra Bonus in soundstage. That set up was the most fun to listen to of any set up I have had. It unlocked recordings secret information; and that was fun. I think you take all the information and experiment? Something does not work, try something else? Gear is easy to sell and buy now. You can always follow someone else's pattern or electronic IQ, mix and match until YOU are happy. B
Bi-amping Rules
I wasn't sure if this question belongs in the amp or the speaker section but I figured I'll post it here. Those of you who have bi-amped your speakers, what's the general rule for deciding which amplifiers are better for low frequency vs. the high frequency drivers. I recognize an accurate answer will depend on the particular speakers and amp combinations but I'm looking for general rules of thumb from personal experiences and not application specific recommendations. For the sake of the argument, let's assume the amps are different but the gains on both amps can be adjusted if that matters. Thanks.
