    • Small and mighty
Color: Black Style: Center Channel Speaker
The media could not be loaded. I’ve had CSI a6 since 2011. I needed to move it from behind my 150” screen after I purchased 2 big SVS SB 17’s as they made dialog hard to hear. It wouldn’t fit in the space on a shelf above the screen I built, plus it’s walnut. This slim guy fit nicely. I set the R350 up and wow I’m estatic. I watched Twister from 1995 and listened to music. Blends very well with my Polk RTI a9’s. I sit 18 feet from it in a large open basement. I moved around the listening area and I’m Very happy with its louder and crisper performance Than my CSI a6. I drive it with 200 watts (which being 4ohms it needs) from an Emotiva XPA 5 ... show more

    • Crushes the competition for centers
Color: Black Style: Center Channel Speaker
I put this center against several other models in and around the same price point and within the same brand line up as well. Hands down, it out performed ALL of them and that was even against the SVS Ultra, the R400, the Klipsch 504C and a couple of others. No shrill, biting highs like several other brands, great soundstage, phenomenal accuracy, and can handle whatever you throw at it. I love it. If you are on a tighter budget and prefer a more Neutral sound, the ES35 has a mighty mouse punch and performance as well. Note, I was actually trying to move away from Polk and just couldn't. The higher end competition just came out too bright and bright means knives going into your ears, not a happy medium. ... show more

    • Very Dissapointed
Color: Brown Style: Center Channel Speaker
I wanted to upgrade my center speaker (Polk TSX250C) which I purchased in 2013 for $299. From all indications, this seemed like a great choice, but I was wrong. The receiver I have is a Yamaha RX-V775 7.1 surround sound with 125 watts of power per channel, so lack of power to drive this speaker was not an issue. My wife said her Sonos Roam (small portable wireless blue tooth speaker) sounds better, and she is right. It just does not perform well at all. Unfortunately I had to box it back up and return it. I really expected better things from Polk. I have a pair of Polk R200 bookshelf speakers on my desk and they are fantastic. ... show more

    • Who wouldn’t be happy with this!?
Color: Black Style: Center Channel Speaker
If you ever get the opportunity to listen to these you will not be disappointed! However, I found in my listening environment the Elac Debut series 2.0 sounded a bit better. Also, the Elac ceiling speakers are far superior than Polk or Klipsch. The Elac ceiling speakers sound like bookshelf or even tower speakers! Plus the Elacs only need 140 watts of power. The Polk 350 requires a 200 watt amp which costs thousands more! ... show more
