Right now I'm running a 5.1 set-up. I have polk r-50's on the front r20's in the rear, and polk center channel. The 8" paradigm sub is on the floor to the right or the tv when you are facing it. Basically the left side of the room is competely open, the right side has a fireplace in the corner and row of doors to the patio. I have a couch on the back wall and recliner next to it. I have the 5.1 set up like most pictures. But I want to add either a 6th or 7th speaker, and this is where I'm lost. Should I push the couch forward and buy a table and set the rear 6th on it, or 6 and 7 on the corner. I was thinking this may be too much noise when listening since they woulkd be ear high and about 2 inches from your head. My next Idea was to set them on the floor behind the couch facing up. Would this be too much of a negative thing? Or should I say heck with the 6/7th speaker and wait and upgrade my speaker?
