Hi there, I'm looking for some advice with regards to additional speakers: centre and rear surround. I currently have Focal Chorus 714 V paired up with a Wharfedale Diamond SW150 Subwoofer, all connected to a Denon AVR-X2300W. I'm generally pretty happy with the sound this setup produces, but would like to add some surround sound. The living room is 5m x 5m, I'm sitting around 3m from the TV and the rear speakers will be no further than 2m away from the sofa. At first I was thinking of a Wharfedale Diamond 9.1 pair and a Wharfedale Diamond 11CC Centre or Monitor Audio Bronze Centre - would that work well? Ideally I would like to spend no more than £200-300 for the additional speakers, but obviously, the less - the better Thanks in advance!
