i have the bose lifestyle v20 system....and it sounds good to me. :shrug:
True surround sound isn't so much about the speakers as much as using the right cables. Dolby digital sound can only be achieved using a optical cable. Get that and you'll be good. The surround sound will be great. Quality of speakers only start mattering when compared to one another and then BOSE will always win.
