I have to say i disagree. I have the previous generation version of his speakers, and while they do sound great, they sound even better with my Rythmik subwoofers. My "critical" listening is almost all music, heavy on the classic rock and pop, also multichannel music which has often had the bass mixed in louder than the original stereo music(Kick sounds totally different because of this, not sure I'm a fan).
Never heard the Monoliths, but from everything I've read here, they seen to a legit competitor to Rythmik sound signature wise.

Don't forget to get an ART cleanbox pro or equivalent to boost and convert the unbalanced signal to balanced, learn how to use a dsp, and JBL doesn't claim 141 db output on these. Also, the one you mentioned has one driver, not two.

You might want to consider the FV15, since you are listening around the house, it will do a better job of pushing the low end around. Where are you located? If anywhere near Austin, TX, you could buy one, see if you like it, and return it yourself(and save the shipping fees on the return). My guess is you'll like it. I think the Monolith 15 is also a good suggestion, as all reports I've seen is that they have very clean bass as well. I'd trust Rythmik's CS over Monoprice, though.
