With the help of this forum, I've pretty much decided on purchasing the B&W 600 Series 3 for my HT speaker upgrade: L-R : DM602 Center : LCR600 Surrounds : DM600 I have also decided on upgrading to the Rotel RSX-1055 receiver. My only outstanding issue is what subwoofer to match with this set-up. I understand that the SVS subs are GREAT and am considering them highly. I just wanted to get some other opinions of other subs that people have with this speaker configuration. Anyone have the Sunfire Tru Sub MKIV ??? I'm also considering this one ... FYI ... I posted a message a day or two ago. I live in a 16x16 apartment with lofted (15 ft.) ceilings. Comments/advice/recommendations ... Thanks.
