Summary: I purchased these TSi's as front speakers for my 7.1 home theater system in my family room. My system is a Sony 46" XBR HD TV powered by a Marantz SR 6005 AV Surround Home Theater Receiver. The front speakers are the Polk TSi 300 floor speakers with a Paradigm Cinema CC Monitor Series center speaker and a Infinity PS 28 powered subwoofer.
Summary: I was blown away at the sound quality of these speakers at this price point of $169.00 per speaker. I've owned Polk speakers along time ago and was impressed then. I was blown away at the sound quality of these new Polk speakers at this price point of $169.00 per speaker.
Summary: with any amp thees speakers sound harsh and sibilant, many normal sounds come out extremely ear piercing. they sound somewhat realistic but with a veiled horrible sibilance behind everything. the sound stage is very wide making everything sound thin and distant except the high frequencies that come out loud and equally as horrible. i have had these for a couple of years now and cant wait to get rid of them. do yourselves a favor and don't go mainstream!
Summary: They sounded somewhat tinny during the first few weeks of use but this gradually went away. They initially had poor bass but again after a few weeks the bass greatly improved when they became broken in. The highs are fantastic. Overall you can't beat them for the price. They have a unique sound quality you will only find from Polk.
Summary: I have both the TSi400 and the TSi300 speakers and I find both sets to be excellent. Nice balanced full sound when attached to my Yamaha receivers. My CDs and vinyl sound better than I ever imagined they could. I purchased both sets directly from OneCall and highly recommend them as a vendor. My speakers and receiver were very well packaged and shipping out by FedEx the same day I ordered them. A tracking number was also provided.
Summary: I researched a number of speakers in this price range and found the Polk TSi300 to have the best all around performance. They are versatile speakers that can be used as mains, as I do, or in various arrangements equally well.
Summary: The Polk speakers sit on both sides of the couch and are pointed to the recliner across the living room. Even sitting in the middle of the couch, the sound is incredible. I have to look around to verify that no one is playing the music live behind me. The value of this purchase through Crutchfield is excellent, the speakers sound great and there are no shipping/handling charges or tax.
Pros: Mid- and high-range response is great!
Cons: Bass is acceptable for the large volume of living room (16x18x20). I retained the use of my Klipsch subwoofer to help complete the aural experience.
