I've got an SVS PB12 NSD, and I sure as hell wouldn't turn it on in an apartment. For the price, it hits really hard. Get the m60s because I'm sure you'll have to turn off that sub on occasion and the m60s do a fair job at bass. I've tried a few other high end brands and the Axioms sound very nice. You'll be very happy with them and they remain very upgradable because they keep coming out with new models that have the same neutral sound.
