You only need to adjust the levels if your amps have different gain. There's a convention but not a requirement for that.
If not, any passive volume attenuator will work. Put it before the loudest amp. :)
Crossover - hard to find for biamping
Interested in biamping a stereo tube amplifier into mid/tweeter drivers, and a solid state Mono block into the bass speakers of a floor speaker.
I probably will need a crossover to adjust levels since i am leaving the internal crossovers inside the main speakers untouched.
Problem is, audio dealers don’t sell crossover Devices and don’t get involved in this area, and there’s very few crossover devices out there.
why is this? It appears not too many people do this sort of thing. Recommendations?
