BIAMPING


Its me again - SFrounds, Need help on biamping questions.

Stupid question#1
Why is it that an amp rated at 125 wpc can deliver 400 watts mono, why wouldn't it be 250?

Now for the rest of these questions, lets say I have two of these identical amps, and a pair of speakers that can be biwired.

Hopefully - not as stupid question#2
What is the best way to wire these amps?

(A)Have one amp wired to supply the low frequencies on each of the right and left channel speakers, and one amp wired to supply the high frequencies on each of the left and right channel speakers.(at 125 wpc each)

(B)Have the amps wired mono at 400 wpc with one amp biwired to the right channel speaker and the other amp biwired to the left channel speaker.

(C) none of the above or other recommended option.

Thanks again, (Don't worry I can Take abuse very well)

I run a tri-amp system using an electronic crossover. I have found that the tweeter gets by nicely with 50 watts per channel but the midrange improved dramatically when it was replaced with a 250 wpc amp from a 100 wpc amp. The mid range runs from 90 to 4000 Hz. My subwoofer uses another 250 wpc amp but it may be more conservatively rated. My impression is that my ears are very sensitive to any clipping in the midrange but not in the low bass and tweeters being more efficent don't need much power to be driven. If the led readouts can be believed, at very loud levels, the tweeter amp is putting out 5 watts while the peak meters on the midrange amp say 50 to 100 watts. I have no meters on the bass amp but I find myself attenuating my bass levels to placate the spouse and neighbours. So go stereo mode and triamp!
