the speakers have a full range input, and low, mid, and high inputs as well. i wouldnt really think of biamping these, but..
the fifteens do not work on the full range input. they work grand on the low input, isolated from everything else. what i'm wondering is this. its no problem for me to power the fifteens with one amp, and the tens/horns with another. the concern i have is, if i plug one amps output into the low input, and the other amps output into the fullrange input, will there be crosstalk? i cant really see how there would be if the low drivers dont play when the fullrange input is used, but i dont want to damage the power amps.
biamping and running active are not new to me at all, but using the internal crossover partially in a cab is. what does a passive crossover have to isolate the inputs? i'd guess there has to be something but i really dont know.
