Summary: I have 4 of the Polk RD85i speakers in the walls of the bonus room along with 2 Polk RC80i speakers in the ceiling and a Polk TSI CS10 hooked up to a Onkyo TX-NR515. The sound is amazing and would like to thank the Crutchfield customer service for their help getting this all together.
Summary: I added this center speaker by Polk Audio, TSi-10 to complete my 7.1 surround sound system which includes two TSi-300 floor standing speakers, two TS-15 front speakers, two Bose 301 rear speakers and a Sony 12" sub speaker, all hooked up to a Sony STR-DH520 Muti-channel Receiver. This addition made all the difference in sound and clarity. It works great with what I have and seems the sound is indenical with the Polk Audio TSi=300's. Simply great.
Pros: Completes the surround experience.
Cons: It is big and needs to be mounted on a short stand.
Summary: It is a little difficult to figure out where you are going to put it once you get it, but it sounds amazing! When setting up the surround sound the receiver did a test on this alone and it sound like it was surrounding me without any of the other speakers even on.
Summary: This is by far the best center channel speaker I have ever heard. Sure, I could go on and on about the clarity - the distinct highs and mids - the sleek cabinet etc. It is a better use of time to encourage you to buy this speaker. It is a large center channel so if you don't have the space in your set up...steer clear until you do. Like others on here, I have mine paired with the TSi 300s and they sound amazing in tandem with one another.
Pros: This speaker locks dialogue onto the screen better than any center channel I have ever heard.
Cons: It's big. Make sure you have the room in your set up.
Summary: The Polk Audio TSi10 did its job well! I have a 7.1 Yamaha surround sound composed of Bose 301, 201, 101, and a Yamaha base module . Polk Audio adds a bit more of volume and crisp sound to the dialog .
Pros: Heavy duty unit, great price, looks nice, great connectors
