For surround sound, skip the BOSE brand. When you go to the store, and listen to a BOSE system you'll be absolutely amazed like the heavens doors have opened up and you're listening to Heaven. You bring it home and wonder what the hell happened!? You then realize, at the store their Demo is of course tuned to their system like surgical precision. I had a moment at the store to say the least and walked home with a $2,800 BOSE surround sound system. Plugged it in, they had me walk around the room with a sensor while it measured sounds at various places and was done. I excitedly put in a movie and the bass was awesome, so wasn't the tweeters (high pitched sounds) but the medium tones like voices could barely hear them. I kept the system for a week playing with the controls, raising the bass, lowering the tweeters, trying to bring up the volume of the middle tones and ended up having to hook up sound to my regular 1985 TV to get those middle-tone sounds and actually hear what people were saying. It was disappointing to say the least, their system is NOTHING but bass and tweeters they have no mids and I brought it back. So, my brother-in-law buys a huge HDTV and gets the Bose surround sound system. As I'm over there, I say hey you have the Bose. He says, I wouldn't get it again I couldn't hear the people talking in the movies and nothing I could do to bring up people voices. I have to have my TV hooked up for the sound so I can hear people talk without being overpowered. Told him, you should've talked to me I went through that! After that experience, to me the most important feature is that it has mids & tweeters for all speakers and a subwoofer. The Bose, or most I know are only tweeters and subwoofer giving them terrible middle-tone capability.
