amplifier match for Eminent Technology

Thankx again. I didn't think that it was that simple. I think thats a very good idea. I have boston acoustics center and surrounds and 125WPC would plenty for them. I really like the Eminent-techs even hooked up to a receiver. I had Bostons VR975's and I think that these are much better. I can't wait to hook them up to something more substantial.

Biamping uses 2 channels of amplification on 1 speaker. This is done most easily 'passively', in which one uses the 2 sets of frequency-divided input terminals on the speaker and drives each of those with a separate channel of amplification and speakercable. This continues to use the crossover in the speaker along with its frequency tailoring, etc. that the speaker's designer labored over to get right*. You could consider passive biamping as a further evolution of biwiring.

Simply drive each of the amp's channels with one signal cable from the preamp going thru an inexpensive 1-to-2 jumper available at RadShak. Since you'll be using identical channels of amplification, no gain (volume) controls are necessary. This does require 4 speakercables instead of 2, but I think it'll be worth it. BTW, if you decide to do this, a 125WPC B&K just might be powerful enough since you'll have 2x125-into-8 available for each channel.

* This point is ignored by those who use 'active' biamping, wherein a line-level crossover is used before each channel of amplification and where each amp channel drives directly each driver. This removes any sonic character, both good and bad, of the speaker's crossover. Of course, some crossovers/speakers have no frequency tailoring to ignore. I know that there's frequency tailoring in my LFT-12, so probably it's used in your 8s too.

Thanks. B&K is high on my list. I don't understand how to "bi amp" Can the Pre/Pro send the mail left and right out to two amps?

Consider a B&K 200.7. That'll give you the extra channels needed to biampify the ETs, and then do that.

I recently went from a Proceed BPA-3 (125x3 into 8; 250x3 into 4) to a B&K 125.7 for that very reason. Am now biamping my center-channel ET LFT-8/bipolar woofer with 2 channels and am about to biamplify my 4-piece, 2-channel surround-speaker systems.
