For $300 the ascend htm200se's would be very hard to beat... I also like the psb mini's, but they cost much more...
I have 2 pairs of the 200se's, one for surround duty in my ht and the other in a 2.1 system paired with custom dual 10" subwoofer{800w, its a carver designed sub}, the 2.1 system has 400watt amp pushing them and they sound incredible, nice tight clear sound, and they get loud in a hurry...
