There are a number of Klipsch owners around here, as a matter of fact. I seem to recall that Doug917 runs some Klipsch's, and he's not the only one. This thread offers a good overview of the different speakers used with the Model 990 while we wait for some Klipsch owners to chime in here, and a brief search through the "Your System Saloon" turned up a couple other threads that may be of interest.
