Summary: I really don't have any complaints with this unit. I purchased Icon series Klipsch towers and surround. The center channel is nice but for a small increase in price I wish I would have went with the Klipsch but I personally like the "highs" that the Klipsch produce. If you're on a strict budget then go with the Polks. If you got a few more dollars then go with a little higher end.
Summary: Although the sound is very crisp, I did have to lower the front left and right speakers to hear the definition from the center channel. My floor standing speakers are far from adequate, but it is what it is. They are very clear but also keep in mind the size of the speaker. Alone, it does wonders with vocals, not so much with music although that isn't a center channel's main purpose.
