But then why didn't the author just say that? Sounds misleading if you read the article.
My understanding is that the hi/mid and low drivers will each get the available 100 watts. So the woofer will never get more overhead than the 100 watt amp provides. However, the hi/mids might benefit by having their own 100watts without the bulk of the demand from the lows eating up available power (if there is that much demand to begin with).
So their might be a bit of benefit from passive bi-amping with two 100watt amps if
some clipping occurs with a single 100watt amp powering both highs and lows. I understand that you are looking at this theoretically as, in practice, it doesn't make a lot of sense to go this way unless you already have the extra amps. If starting from scratch, buying a more powerful single amp, say 200wpc, would provide more benefit as the lows would have access to more than 100watts, if needed.
This help any? @experts: Do I have this correct?
I just recalled some experience with this a couple of years ago. I used to have an Onkyo 5008 AVR rated at 140wpc. It had something like seven amps in it and I only needed five (for my 5.2 channel system at the time). I wasn't happy with the sound. The Onkyo could be configured to use four of its amps for bi-amping the front channels. I tried this. Thought maybe it helped a little, but not enough to be sure. It also allowed for bridging two pairs of amps. I tried this and was confident I got a less irritating, smoother sound. No DBT, but went back and forth from standard config to bridging and liked what I heard.
This experience is replicating the two 140wpc amps per channel for passive biamping vs. one 280watt (?) amp for each channel scenerio.
Keith, I recall you were in on that discussion way back when, if you recall. Did you try anything like this?
(I now have the 5508 Onkyo pre/pro and external amps instead of the 5008).Edited by pstrisik - 9/29/13 at 11:29am
