I have the following setup Front B&W 603 S3 Centre CC6 S2 Rear 601 S2 Sub 675 Thinking about going to 6.1 and wondered if anyone had any suggestions. I'm a little confused on the issue of the extra channel in 6.1 & 7.1 systems. Is it a rear or a side channel? I know there is differences between descrete and matrixed but not worried about that. I had thought of the following cc6 s2 to the rear 601 S2s to the sides buy LRC60 for front but this gives me a mono rear. Is this Ok ? Alternatives I had thought of were get another cc6 2nd and put both on the sides buy LRC 60 for front or get a set of DS6 (if I can find them) and put those on side Any suggestions ?
