Biwiring with separate cables for low and high end

If your mono amps have 2 sets of speaker outputs, why not use them. One set for the highs, one for the lows. I think that's what they are there for.

Unless using both sets of speaker outs would make unacceptable demands on your amp. Does your amp have a load warning? Mine does. I can't use the second set to bi-wire a speaker. It will see two 4ohms speakers in parallel. I wanted to try a biwire configuration at amp end so I did even though the cable manufacturer didn't recommend it. Then the cable manufacturer told me to add jumpers (made of the same cable) so that the upper and lower range were strapped as well as biwired. Sounds significantly better. Don't ask me why.

If you have two pairs of outputs on each of the amps, and two pairs of inputs on each of the speakers; use two separate pairs for each channel.

Lynne (Arnettpartners), biwiring from two sets of output terminals on the amp will not change the load impedance that the amp sees, relative to what it would see in any other connection configuration.

Regardless of the connection configuration, the speaker's crossover network will cause the amp to essentially just see the low frequency driver(s) at low frequencies, and to essentially just see the mid/hi driver(s) at mid/high frequencies. At frequencies that are within the crossover region, that are reproduced by both low and mid-frequency drivers, the amp will see whatever the speaker's impedance is at those frequencies, regardless of the connection arrangement.

Like the others, I don't see any reason not to use both sets of amp terminals. Although of course whether that arrangement will work better than, worse than, or the same as connecting the two cables to one pair of amp terminals, or using either of those arrangements plus jumpers on the speaker terminals, or using a single-wire arrangement with jumpers, can only be determined by listening.

Thanks, Al. I was thinking about putting in a 911 call. I will have to digest that. This also means that I can reconfigure.
