the impedance changed dramatically once the the crossover was separated.
So from a technical standpoint it makes a difference?
No, it doesn't.. All an amp is, is a voltage source.... The speakers are the load... If you have an amp that is designed to be a constant voltage source, then as the impedance halves the output power doubles.
If you look at the large Krells, or Mark levensons they double in power down to .5ohms.. some even lower than that..
By Bi amping, you can buy two less powerful amps than buying one large amp.. Granted this is not the most efficient way..
A prime example of this is the Bryston Model T's as they are designed to be Tri-amped.. Each different set of speakers requires a different amp. James most likely did this because he wanted to use an active cross over to have maximum control over the frequency curves. This is slightly different than the conversation in this thread, but still loosely applicable.
