Summary: Got this baby for a great price and am very happy with it. I got it to voice match a set of rti4's that I picked up which I also love. Polk makes some great speakers, and Amazon has some great prices on them if you can be patient and wait for the right deal.
Summary: PROs: Brilliant sound. Fills out the front sound stage exceptionally well. Vocal clarity is top notch. I have found in my ownership of this speaker (since 2008!) that it is very versatile and pairs with most mid to high end speakers surprisingly well.
Summary: I had this speaker before and loved it. I ordered this for a friend and he loves it as well. Polk Audio builds some excellent quality speakers for a fair price. I recommend these for any low to mid range theater setup.
Summary: Very clear sound, blends perfect with polk RTI10 towers and polk 70RT surrounds and 70RT front high channels for home theater. Set at 80hz crossover. Compared to the polk monitor series center channel and towers that I own and use in game room, there is a very noticeable difference in sound quality.
Summary: Bought this speaker recently to finally piece together a decent home theater for my place, and I was amazed with the value it offers. For less than a CS10 (Polk's budget offering) locally, you can pick up this speaker that was once Polk's second best home theater center.
Summary: I purchased the CSi3 at the same time as I purchased FXi3s (surround speakers). My mains are Polk RTi100s (no longer manufactured). All speakers are seamless and provide a wonderful soundstage for games and movies. Specific to the CSi3, they sound great with life-like reproduction.
