Hey, first-time Klipsch purchaser here. Got the RB-81's at a local home-theater emporium, and I have to say that I am amazingly impressed. Was expecting some harshness or screech in the highs, but these guys seem so incredibly smooth throughout the whole spectrum. And, man, they play loud, the biggest issue is taming them for low-level listening in small living room.
Using with the Outlaw RR 2150, lucky that I am to have it. And NAD 542 CD player along with NAD 33 table.
2 channel all the way.
