Bi-amping Question?


I am and amature to highend audio and am trying to get into it by first messing around with low-end eqiupment and learn concepts. Quick question. I have a pair of Wharfedale Diamond 8.4 (rated at 150W-RMS 6ohm impendence). Additionally I have a ROTEL RB985 (5 channel at @ 100W per channel at 8 ohm.) Could I bi-wire/bi-amp the Diamond 8.4s using two outputs for each speaker from the amp (i.e. Use Left Front to power Low Frequency of the Left Speaker and Left Rear to power the High Frequency of the Left Speaker and use similar setting for the right speaker). Since the Stereo pre-amp I have has two outputs for each channel, I was planning to connect Left out to Left Front and Left Rear and Right out to Right front and Right Rear on the Rotel amp. Would this actually make a sonic difference? Putting 100W in High Frequency and 100W in Low Frequency = The speaker being powered with 200W or is it still effectively 100W? Any ideas-under the assumption I am buying no additional equipment?

1. Wiring inputs and outputs that way will work just finely.
2. You may or may not hear a difference. If you don't have to buy more speakercable, TRY IT!
3. You will be driving your speakers with 400 Watts of rated-maximum power, and the sound should be more dynamic unless you listen at quite-low volumes. Actually, with 6-Ohm speakers, your amp channels could drive more maximum power, say, 150 Watts each, which is around the maximum-rated power of your speakers, so be careful--if you're a headbanger, you may be blowing drivers soon.

"...if you leave the speaker crossovers in circuit then you are simply running bridged pairs of channels to each speaker, not biamping."

Nope, you're wrong. The 'bi' in 'biamp' has to do with using at least 2 channels of amplification PER SPEAKER. 'Bridging' channels of an amp is completely different and has nothing to do with how you're driving the speaker.
