In fact, unless you listen to a lot of classical or electronic/pipe organ stuff, consider going without a sub as a possibility.
The M80s really are a capable speaker.
I think FredK is correct here. Probably my experience with the EP175 was to be able to increase the volume or gain of lower freq. (below 60 hertz). For a little more bottom end, instead of hearing lower freq. than the M80's can deliver.
This was nice for jazz, rock, and many pop recordings that seem to be recorded poorly. It was a way to enhance the kickdrum, and electric bass in some of those recordings. I suppose increasing the bass knob on my processor might have given me similar results, without being able to control the crossover.
