impedance question with bi-connections

tugzy

I had a thought when it came to the bi-connections on the rear of my A9's. If you Bi-wire the speakers using a single amp vs Bi-amp using two amps, are you getting a different impedance load? Bi-Wiring is effectively wiring the high and low drivers in parallel. So if the A9's are rated 8ohm normally (with bridge plates) does that mean that the high frequency and low frequency drivers individual connections are rated at 16 ohms each? Or are the HF and LF 8 ohms and remain 8 ohms when connected? That would go against ohms law ...

wow, nobody?

The reason it is 8 ohms either way is due to the crossover. One set of binding posts goes through a high pass filter for the tweeter, while the other goes through a low pass filter for the woofer. When paralleled with the jumper, only the highs are going through one set, and only the lows are going through the other set. So, one posts impedance means nothing to the other. They're both only working with a certain set of frequencies.
