Darc, if you are in an apartment bass from any floorstander speaker or subwoofer will get you complaints. The M80s play down to ~34hz and that kind of low end will go right through any wall, just the same as if you had a subwoofer. Once a sub is properly calibrated with the mains it won't be playing any louder than they are and will not add extra bass(loudness) for neighbors to complain about, at least no more so than a set of floor standers like M80s would.
