And even though you say that is what you have been posting about, you HAVE repeatedly confused the terms biwire, passive biamp, 'passive' (aka fool's) biamp, and active biamp throughout this thread.
Please, take a minute to step back and see the difference between all those as they might apply to pro audio versus home audio situations. Particularly the difference between what is diagrammed in the first drawing of passive biamping versus the 'passive' biamping that is afforded by AVRs and the 'passive' biamping that WE are discussing. They are very different. When you understand the difference, you will see the confusion.
'Passive' biamping around here refers to utilizing separate amps to drive the individual sections of a speaker's passive crossover. NOT what is diagrammed here:
OK? This is NOT what WE are talking about when we talk about 'passive' biamping (or even passive biamping, for that matter). I think you understand all this. Let's not bicker just because you don't understand how WE are using the terminology.
In the audio world technology has changed, terminology has not changed. "fool's" bi-amping is indeed bi-wiring a speaker. you are using 1 amp with four speaker wire leads connected to 2 output poles on the amp(1 output not dual out's) to to the hot and cold on the speaker, so you are making 2 connections at the amp and 4 connections on the speaker. active or passive has nothing to do with this. That is why it is called "fool's bi-amping" You are using 1 amp to power a speaker array build for 2 amp inputs.
Andy, please. Obviously, you don't know what you are talking about. The best approach in your situation is to ask questions and read the answers. Posting misinformation is just going to keep people posting to correct you. By the way, there is no such thing as a passive amplifier. The active and passive element we've been talking about is the crossover.
I really do not understand why this is so hard to understand. A passive system amplifies – necessary for the transformation into sound waves –
the music signal "externally" whereas an active system has "integrated" amplifier
So this same process is different from pro to home products? I don't think so.
