Having trouble deciding on SB-2's or RB3's as main speakers for a HT/2Channel setup. I drive mostly 2 Channel music, but do continously have the speakers on for general TV/movie viewing and of course, DVD. Limited on space, so no stands either. Any downside to the SB-2's? I see so many reviews for the infamous RB5's, but nothing on the SB's versus RB's. I have Synergy SCW2s in the rear and felt better matching with Synergy series, but again, unsure to step up to Refs. Drive the system with an HK AVR85 (75 wpc)and have Velodyne 10" sub. (which is real nice).... Thanks in advance, everyone....
