OK, here is the situation. I could certainly spend more if need be, though my wife may ask for a divorce. We are having our 3rd floor attic converted into a media room starting in January, so I have time to research. The room is about 800 SF, though we don't need sound in more than 1/2 of it. The center of the room is 9' high. It is flat for about 2' and then will slant down to 6', with regular vertical walls at that point. I don't foresee any time when we will have more than 8 people in the room. And usually 4 people or less. I don't even know what 7.2 is, but I do know what 5.1 is. I have 5.1 in my family room, and I am fine with that. Not sure I even want 7.1, let alone 7.2. My budget for audio is $2000. I know I would like dual zone so I can have sound in my master bedroom below the media room. So that will need at least one, if not 2 speakers for the bedroom. I don't know what more you might need to know. I was looking online at the Yamaha RXV 671, I think the model is. I have never heard it or seen it in person. And I have no clue what I can do for speakers. I was figuring up to $700 on a rcvr, and the rest on speakers. Any recommendations? BTW, I like a sub like most people, but I don't need the windows and walls to shake, LOL.
