Has anybody heard the STF-1? Is it comparable to the EP125? I'm still not really sure what to get. This will be inside a dorm-sized room, but the M22ti's will be the perfect height on my desktop (the M2i's would be too short). Could someone please explain how this crossover works? I thought that subs could take care of the bass (say, from 90Hz down) and not send the information to the speakers - leaving the bookshelf's to reproduce the mids and highs.
