I currently have KG4.5 as my mains with a SC1 center, SS1 rears and KSW12 sub. Because my entertainment center needs to be wider in the middle to accommodate greater than 43" TV, it will squeeze my KG4.5 more than than they can move. So, I need a speaker that is roughly 9" that can be slid into a spot that has a cabinet to the side and a wall on the other and in back. Height is not an issue. I was looking at the RF-82 but I a little worried about the rear ports. Budget will be about $1000/pair give or take a few hundred. Any suggestions? thanks!
