The Infinity TSS-500's I have came in a 5.1 kit. The satellites are.... ok, but a little tinny for my taste. The center is better, but still a bit tinny. This Cerwin Vega is a beast - it has two six inch cones, a tweeter, and a port. It should have much better frequency response than the Infinity center. I'd really like to use it, but am afraid of what it will do to my AVR.
Oh well. Got a call in to HK about it, as well as CV. I'll see what they say about it.
