Last week I purchased a RC-62, RS-52 and a RSW-10d to go with my main KG5.5's, this week I bought a Denon AVR-3808ci to complete my 5.1 setup. I still have a lot of setting up to do but all I can say is WOW, I've really been missing out.
Last night I tried a movie for the first time with the setup and I ended up watching the whole thing (3:00am) I was so impressed with the sound, I got a lot of joy out of watching the movie because of the sound.
The RSW-10d hit some low notes (foundation shaking) without loosing control or drawing attention to it's self, the bass was just there when it was suppose to be. While reading audio forums, you discover that Klipsch subs are not the first choice with other people. there might be better subs out there, but knowing what I know with the sub that I have, I would not want to roll the dice with any other sub.
I'm sure my system will sound better when I get it properly setup.
