Basically, I have a narrow sound stage (about 6'), and an interior designer for a wife. I can't fit floorstanding speakers to the side of the TV, they would have to be bookshelves that sit on the cabinet that runs under the TV, and they can't be bigger than say 10"x6". I have less than 6" above the cabinet and the bottom of the TV.
Also I should point out that my wife and I sometimes have a hard time understanding dialog, so that is a priority for sure (right now we have an ancient Infinity center, C1 I think).
So, I am wondering if we should go with a relatively bigger center (though slim), compared with the sides? For example a BA RS 223 or Yamaha NS-C310BL with small matching bookshelves. Or am I better off with the bigger sides and a smaller center? The 3 speakers will all be so close together, I know I don't want 3 large speakers there. The viewing are of the space is about 13' deep by 20' wide.
Thanks in advance,
