Hi all, Don't know if this post belongs here or not, but here goes. I have a small dedicated HT that's about 13x10.5. My RPTV is along the long wall. I currently have a 5.1 setup, but am planning to upgrade my receiver to a Denon 2802, which is of course 6.1. My question is should I buy an additional rear speaker (I'm using the M&K k5s) or should I just stick with 5.1, given the size of my room. Any help would be appreciated. Thanks.
