My subwoofer adventures began when I was more focused on home theater. I ran a mix of ported and sealed subwoofers with no ill effects and used them for music also. I currently have two SVS SB13 Ultra subs and two Rythmik F25 subs (all sealed). It's overkill, but I have a large room that opens into my kitchen. I think you'd be fine going with some smaller subs like the SB1000 or some of Rythmik's entry level subs. That's one of the great things about combining multiple subs is the headroom you get.
I have secondary systems that all use a single sub and the one in my computer room in particular is capable of stunning sound quality. A single sub blended properly can fill in the bottom end, especially if you're using smaller monitors. I have Harbeth P3ESR in the computer room and the sub adds just enough to add some realism to the listening experience.
Having said that, there's nothing quite like being completely engulfed by the sound in the way that you are when using multiple subs.
