Sorry I wasn't specific ..... The crossover is on the sub. This system is for music only, Amp, pre amp and cd player.
I have the m2i's on stands about 4 1/2 feet apart and the sub is in the far right hand corner about 3 1/2 feet behind the m2i's. The controls on the sub are Crossover 80hzto 120hz, phase adjust and input level.
