Bi-amping

I have a 7.1 set up. RTi 10 front's, CSi5 center, RTi6 for surrounds and backs. I am running A pair of Anthem MCA amps (20 for the left and right and a 30 for the center and surrounds). I was thinking of trying to biamp the Anthems. Keeping the left and right RTi 10's on the MCA 20, but only the top end. Use a the MCA 30 for the low ends and center channel. Then use the Yamaha 2400 receiver for the amps to the surrounds and backs! In that way the power would be all going the the front 3 speakers that carries most of the important sounds. Then later when more money opens up, get some mono blocks for the surrounds and low end of the center channel which would only be running off the one MCA 30 amp. What do any of you people think? An I waisting the amps by driving the hi and low separatly?! I have always hear that RTi10's need power?! :cool: :confused:

    I used a couple of "y" adapters for the left and right preouts and ran them to a two channel amp (200 watts @ channel) and to a three channel amp (180 watts @ channel). From the two channel amp I went to the mids and tweaters and from two of the three channel amp, I went to the woofers of each RTi 10. the third channel of the three amp I sent to thr center channel (CSi5), to run the whole speaker. The surrounds and backs are being run off the Yamaha's built in amps (rated at 120 Watts @ chennel). Is putting Y adapters on the preouts the right or efficant way to go to biamp my RTi 10's? I thought biamping the fronts were a better use of the amps, than sending them to power surrounds. I know I would like to get a mono amp to run the woofers on the CSi5. Do you think that biamping all three front channels is the way to go? :confused:

    I think you would want 200 wpc powering the woofers and 180 wpc powering the mids/highs...

    I don't see the need to bi-amp the CSi5 as it has a max rating of about 250 wpc...

    But,everyones taste are different,that's what makes this hobby soo interesting.

    thanks for the input Mike. I can easily switch around the lines from the two amps. I am also running a HSU VTF2-MK11 subwoofer at a 80HZ crossover if that makes a difference. I guess I was worried about signal loss because of adding in the "Y"'s would off set the gain of running two amps? Didn't know if there was a better way. :D

    As long as you're using good cables/splitter you should'nt loose much signal...The best improvement to a system,to my notion,is to have seating, speaker placement,and calibration fine tuned...

    Once these basics are done,then you can start tweekin the small stuff...

    To a Bi-Amp setup? I've been running my 70's without it, thinkin' I may try to set them up in a Bi-Amp configuration if there is any big advantage?

    Or it really doesn't make much difference?

    Big difference, I noticed the range opening up. the hi's were higher and the mids seemed more open. I didn't notice anything different about the base, but I do have a good subwoofer (HSU VTF2), so I don't think I would notice it. My next project is to biwire the center channel and up scale the wires. What I done so far with the biamping has been worth it.
