Not sure what you mean by a "bedroom" system, but if you're planning on putting the Spica on a dresser or something you might as well go with something else. The Spicas need to be optimally set up in order to sound like a Spica should. And that means room to breathe.
I'm not sure they sound "better" than other top-notch monitors available today, but they will definitely hold their own and not be embarrassed by any.
One thing, though, is they're kind of big for a monitor. If your bedroom is one that's average in size, with all the furnishings that typically go into one, I'd probably opt for something like the AudioEngine B2.
Good luck.
