I just ordered a pair of the R 820F. I saw somewhere it said the sale ends tomorrow. This seems to be a pretty good deal. I currently have a pair of F30's from the synergy line as my mains, RP-450C as center, 2 R-12SW subs, 2 RP-160M as surrounds and 2 R-15M as front height. Think the 820F's will be a better fit than the F30's? If nothing else, im all copper now lol.
