Yeah, the bass is smoother - in fact, it's perfectly smooth, and the little 10", sealed subs have great 'character'. It's been the reference that I've been struggling to match with the big system. Now, the bass in the main system goes deeper with more authority and it's blended nicely, but there still exists a little added emphasis here and there - I intend to add some more traps.
The imaging is altogether different between the two systems, as you might imagine. The bedroom system doesn't have openness and spaciousness of the main rig, but it's fantastic left to right. Due (I'm guessing) to the proximity of the left wall, sometimes sounds seem to come from behind me (on my left) - spooky.
