Summary: I just put together a new home theater system using TSi300's as the front speakers, TSi100's as the rear speakers, a TSi CS10 as the center speaker, a PSW125 sub, and a Sony STR-DN840 receiver. Everything sounds great so far. I have no complaints.
Summary: I could not be more impressed by the value of this 'little' center channel speaker. I must admit that I was a sort of disappointed by how large the speaker box is after I set it up, but after a few days, I don't notice it and the sound of my movies is so much better. My girlfriend no longer lunges for the remote during action scenes, and dialogue is incredibly clear.
Big Size with Great Sound, Better to Pair with other Polk Audio Speakers

Summary: Although I'm aware of the dimension of this center channel speaker, I still got shocked when I unpacked the package. It is a huge unit and I'm really glad I didn't choose the even bigger CS2 (even if it should sound better). First of all, you have to make sure you have the room for a solid 7 inch high box. I replaced the center of my Energy Take Classic 5.1 with this CS1. The first impression is disappointing.
Summary: This is a pretty good speaker when accurately paired with the TSI 400 front channels and the Polk Sub. Adding the center helps render dialogue better and you don't need to turn the volume up really high. This is good because when you turn the volume up to hear dialogue, music, explosions, etc... will rock your house.
Pros: -Affordable -Easy to shelf Mount -Helps with dialogue -good looking
Cons: I think it could be a little more potent. While the sound is clear it is not very loud. Now, this could be due to either or both of the following: 1. The speaker is not fully broken in yet, I have it only a few weeks. 2. I am in a 420 square ft room with 13 ft ceilings at its peak. It's possible I should have upgraded to the TSI 500s or the RTI line. If either of these things are true it is not the fault of Polk. It's still a very good speaker.
