I’ve read a bit about how adding a subwoofer to a 2 channel music system isn’t just about adding bass but taking the lower frequency work to the sub so the mains can shine.

I have a Cambridge CXA81 that has a mono sub out, but the crossover setting would be on the sub not filtered at the amp.

So is this actually taking the load off the mains, or just adding TO the mains? Or (newb ass question here) is the lower frequency going to the sub because that… how do i say… window is open now?

    It’s not the speakers you need to take the load off of. It’s the amplifier(s).

    It’s amplifiers that have the real issues with low frequencies.

    Adding a subwoofer channel will increase whatever frequencies the sub is playing.

    But unless you are crossing over prior to the signal reaching the amps, you aren’t going to get much benefit in clarity. Which comes primarily from eliminating slewing sag in amps required to simultaneously produce low and high frequencies .
