I have a 7:1 Speaker system from Polk Audio. This system sounds great, but I have no need for it when I got the Bose. I originally got these as a 5 speaker set (RM 6700), but I bought two more speakers that were from Circuit City. These speakers are in great shape except there are two that can't be used with a speaker mount, because the screw hole was stripped. I love the sound there produced. Here is a review about them.Polk Audio RM6700 Surround Speaker System reviews - CNET Reviews I am also including Omnimount speaker mounts for four speakers. I'm asking $150 shipped.
