I've never really paid much attention to the CS speaks. I've always been interested in HPMs. My nephew started looking at the CS series to go with his newly purchased blue faced Pioneer receiver. Much to my surprise he wound up with a pair of CS-88a and they sound darn pretty good. What really surprised me was the build quality. Although the grills on the CS series look like something from a funeral home, they are made out of solid wood. The boxes are nice and thick. Now it looks like Pioneer just threw as many speakers into each box as they could fit. The 88s being a six way speaker. Even so, the CS line turned out to be a pretty good, be it, quirky line of speakers. For $50 bucks for the pair, I'd say my nephew made out pretty well.
