Is there a difference? The booklet that came with the speakers has "KSB 1.1". I had a pair of KSB 1.1's a couple of years ago, and I am pretty certain it had the "S" in the model number. "part number on box states 090317081210". The speakers were factory sealed. They look just like the kSB's???? Anyone know?? Thanks in advance. Bob. Brand: Klipsch Type: Front Right and Left Speakers Shape: Rectangular System Configuration: 2.0 Channel Color: Black Model: KSB 1.1 Connectivity: Wired MPN: KSB11 RMS Power: 75 W Nice little pair of working speakers.
Pair of Klipsch Synergy Series KSB 1.1 Bookshelf Speakers with speaker grille cover. They have been tested and are in full working condition. The back features two speaker terminals that fit a standard size banana plug adapter and the possibility of adding a speaker mount.SPECIFICATIONS:.. I currently have a set of Klipsch ProMedia satellites and a Sony subwoofer in my HT setup. If I were to get the three speakers from CL, I'd keep a pair of the ProMedias as the rear channels (or maybe go bananas and set up for 7.1), with the KSB 1.1s and KSC-C1 up front.
