How do I biamp with older receiver?

[Beegowl]

Would there be any advantage to biamping my speakers using my old Yamaha RX-V596? I recently bought Yamaha RX-V1500, increasing the power output to my speakers. My main speakers, Tannoy DC3, can be biamped. I'm not sure how to go about this or even if it would be worth the trouble. Any suggestions?

Thanks.

Use the more powerful (the 1500 i think) amp to pump the woofers and the other to pump the tweeters; the only thing you could loose are a couple of bucks to buy the speaker cable, just be careful not to put them into shortcut.

I'm using and HK AVR70 (for the bass) and a Yamaha RXV1400 (for the tweeters) to biamp my fronts and i have noticed a little better definition in the low end. Of course, it's my opinion and i haven't proved it in a DBT.

Gracias, Toquemon.

After searching the forums for information about biamping, I'm puzzled. If I biamp, according to one thread, I need to buy an external crossover and disconnect the internal crossover in my speakers. I'm ignorant technically, but it seems that driving the speakers' woofers with one amplifier and the mids and highs with another would supply that much more amplification power to them, providing the power to reproduce the signal more accurately and wouldn't have anything to do with the crossover frequency, particularly if the speaker has inputs for biamping. Although, it's true, the signal would be a full frequency signal that couldn't be totally reproduced by the respective speaker unit, wouldn't you still get the benefit of increased power?

What you said in bold is exactly the issue. Each amplifier will amplify a full-range signal and then the speaker's crossover will filter out the frequencies it can't handle. So the amplifier wasted its time amplifying frequencies that won't be used and it's no different than not bi-amping in the first place.

With an active crossover before the amp, the amp will only see and amplify the frequencies that you intend to pass on the respective speaker driver.

Thanks. Biamping requires more than just hooking up another amplification source to the speakers.

What you're saying is that using two amps without an external crossover is no better than biwiring, as far as any advantage in sound quality. I'll just stick with my setup as is because I don't believe biwiring is advantageous.
