I have a similar question as the person below regarding the Polk Rti Line. I currently have a 7.1 JBL studio series setup. S310 Fronts S Center S26 Surrounds S38II Back Surrounds I am not necessarily considering a change because of performance (I love the JBLs), but I have always been curious of Polk and I love the look of the Rtis. I am thinking on going with: Rti8 Fronts Csi5 Center Fxi5 or 3 Surrounds Rti6 Back Surrounds I don't have an option for a side by side comparison, so is there anyone out there who has an educated opinion on these two speaker lines (perhaps someone who has either heard or had both). Any help would be GREATLY appreciated since I am seriously torn as to what to do. Thanks folks!!
