Biwiring and impedance

More specifically, how would this work out?

My amp has two sets of switchable speaker terminals, "Spkr A" and "Spkr B".

If I single bi-wire, I'd have a single pair of bananas connected to the amp's Spkr A terminals, but which would diverge into separate speaker leads to go to the woofer and tweeter inputs of the speakers.

If I double bi-wire, I could connect one set of spkr cables from the Spkr A terminals to the woofers, and run a second set from the Spkr B terminals to the tweeters.

The Spkr A and Spkr B terminals are wired in parallel. If I were to connect 8-ohm loads to both pairs of spkr terminals, the amp would see 4 ohms.

So in this case, wouldn't my amp see a different load with double bi-wiring than with single bi-wiring?

Hold on, folks. It doesn't matter at all what the impedances of the hf and lf parts are and it doesn't matter whether you use single-biwires or double biwires or how many terminals there are on your amp.

If you connect everything to one amp, regardless of the wiring, the impedance load is the same as with single wiring.

Sheesh!

Thanks Kal. That's what I was looking for.

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.
