Personally I prefer separates and I don't like to idea of being stuck with a speaker manufacturer's choice of amplifier.
I don't like the idea of being stuck with a manufacturer's choice of passive crossover, with the many feet of lossy wire (air core inductors) and a whole bunch of electronic parts that have "a sound" now stuck forever between my amps and the drivers where the sound begins. With active, I can get the crossover part done BEFORE the amps at line level without any loss and I can control driver phase to get a phase linear system, and I can get rid of the biggest lossy thing in the entire system, the speaker cable. Just sayin....
This isn't controversial is it?
