Bi-amping + speaker crossovers = redundant?

This will get complicated as the electronic crossover will have to be placed between the signal source and the two amps if it is to divide the frequency between them. I am having a little trouble visualizing the exact configuration and I have a fairly complex system. The signal cannot pass through the 'Master" amp to the "Slave" amp as it will not be the full range signal, only the partial signal. There is no way I know of to place the crossover between the amps and the speaker as it acts on the signal, not the amp output. It will feed two separate signals to the two amps and you are back with two volume controls. There is a reason why, despite their many drawbacks, almost all speakers are passive. KISS rules again!

OK, I finally thought of how it would work. Signal to one pre section, then to the electronic crossover , the signal is split and the level balanced with its volume controls, then out to each of the amp sections, not using the second pre stage. But you will still have the problems Drew described. Last winter I considered something like this; I have 6 identical mono amps and speakers that are tri wirable with easily removable crossovers. I gave up when I started to discover SOME of the problems Drew spoke of. These projects are best left to the technically gifted who enjoy the construction as a pleasure in itself.

I use three way tri amped system. My system was built that way, however, you can do it yourself. You can use an external xover such as the Bryston 10b xover. Pre out to cross over the to three matched amps amps to the speakers. The volume control is at the preamp and used for all channels.
