i am kinda confused on this one , yesterday i was at my local Klipsch Dealer and checking out the RF-3 II, the sound is just amazing. These suckers kick ***. i was Planing on gettting the RF-3 II along with the Ksw 12 subwoofer, the one thing is they had the RF-3II hooked up with a Ksw 15 sub, He turned on the system and played the dvd Gone in 60 Seconds, the sound of the bass was awesome, just to know what would you guys recommend, the Ksw 12 or 15 for the RF-3 II? anthor thing i am gonna buy the Denon 2802 reciever, will this reciever output enough power for the Ksw 15 sub? They had a Intergra THX Amp, i dont plan to get something thatr big.
