Bi-amping

There is a lot of information on active bi-amping apogee speakers, but quite a few people don't like the sound as much as the passive crossover. 

Passive bi- amping can be achieved before the amps, given the right speakers. Marchant makes a passive line level crossover for this.

The Cable Company sold me bi-amp speaker wires and said this is better than using jumper cables.  They didn't cost that much more.  Who knows if any of this makes any difference. 

This can make a big difference on certain speakers and not make any difference on some speakers. I tried using jumpers and one set of cables on my apogee duetta 2's and it didn't sound near as good as using a set of bi- wire cables.
