If your crossover is external (ie, before the amps in the signal path), then you're actively biamping. If your crossovers are internal to the speaker, but the speaker has separate binding posts and you're using 2 separate amps (possibly with separate power supplies?) then you're passively biamping. If you're using 2 runs of wire to 4 separate binding posts, back to 2 binding posts on the amp, you're biwiring.

This oldie-but-goodie has some discussion on the subject.

It's clear that even in passive biamping the speaker has more wattage available. Now I need to actually do it and see/hear if it makes a difference. I'm just not sure if I want to play them that loud. They already get 200W each so I'll do this when I'm bored one day since I have the cables and connectors.
For now I'm happy just listening and not tinkering heehee Actually, that is incorrect. We've been down this road a million times, so a quick search should provide all the info you need. But the bottom line is no, you do not get more wattage. Of course, it does not hurt to try. In fact, what fun would it be if we couldn't tinker? I have searched plenty and my conclusion is that if you have a receiver or an amp with a single power supply there will be no difference. I have 7 INDIVIDUAL amps though, each with their OWN power supply and completely independent circuitry except for the wall outlet.

To save some time, i think his point is that the amp will only provide the maximum current available, no matter how many paths you provide for that power. Unless you have independent power supplies passive bi-amping is really just bi-wiring. For example, I bi-amp in my car, where the cross-over gets a signal for the tweeter from a good moderate power amp, and the mid-bass gets a signal from a more powerful amp. That is true bi-amping (as I understand it).
To be clear, I'm not implying you didn't' know this, just figured many readers are on different places on the learning curve. (Be damn funny if my example was wrong!) See my above reply.

I'm very clear on the differences between active bi-amping, passive bi-amping and bi-wiring.
My argument is that if you have individual amplifiers each with separate power supplies and you assign two amps to each speaker, you are in fact delivering more wattage.
I'm not referring to configuring your receiver to bi-amp or using two channels from a 5-7 channel amp for a single speaker. I'm talking about assigning two SEPARATE amps to each speaker.
Can someone explain how this would not provide more wattage? I've searched and nothing indicates this.
I'm clear that true bi-amping requires the disabling of the internal crossover in the speakers and adding an external crossover, but passive bi-amping with two individual amps should still provide more power.

You are in fact NOT delivering more wattage to the speaker, unless you get rid of the internal passive crossovers in the speaker and use an external setup, as we have mentioned.
300 watts to the woofers, and 300 watts to the tweeter/mid section is not giving you 600 watts.

I'm not saying it would deliver twice as much, but if one amp delivers 200watts and and I connect one to the mids/highs and one to the lows, even if some wattage is lost in form of heat(crossover frequency filtering), I would still get more than 200watts to that speaker, even if only 220watts total. No?
