Biwiring and impedance

Not neccessarily guys. Buffered amps and throughput (Krell) amps can see a super low impedance from the high freq posts. Depends on the crossover. Do a little homework on the speakers you want to try this with if you are not under warranty.

Really? What crossover configuration would have the HF present as a low impedance that is not seen when both HF/LF sections are connected?

I am not trying to be wise-guy but would like to know if such is possible.

Kal, It is quite common in first order crossovers, both the woof and tweet work far outside their sweet spot with such a gentle slope. Tweeters particularly drop impedance in this situation. Amplifier say POOF! If the amp can handle very low impedance, tweeter say POOF! Been there- done that.

OK, that is not too uncommon but the effect would be the same (if not worse) with the the woofer connected. Any woofer load would be in parallel with and, therefore, would lower the impedance even more.

Besides, the same amp is connected to both HF and LF, in parallel, even when biwired.

So, the issue has nothing to do with biwiring. It is just the usual question of whether an amp is stable with that load under any circumstances.
