Hello,
I have a pretty decent sized room that i currently have a R-SW10 in, the room is 26ft x 17 ft, its a living room dining room combined since there is no dividing wall. I sit maybe 5-6 feet away from my tv where the speakers (r-15m) and subwoofer are. I found an R-12SW for $62 more dollars then i spent on the R-10SW about 20 miles from my house (a total of about $340 for the R-12SW). Is it worth the extra 60 bucks for the 2 inch bigger sub? Or will 10 be fine to fill my listening space?
