Very clear!

I replaced a B&W CC3 with this and don't regret it. I'm amazed at polk's technology and prices. Beautifully clean sound! Sarah McLachlan, Neil Diamond, Diana Krall etc all sound amazing. I just had to increase the centre volume a bit because this one is ever so slightly less sensitive. But the clarity of the voices and the highs are great! Even the lower tones.

Polk Audio CSI-A4 Center Speaker

Replaced my old Cerwin Vega Center with this Polk Audio CSI A4, its perfect, clean sound, nothing to complain about! running it with a Yamaha 130 watt per channel AVR, and it's smooth! Center speaker is key for movies as vocals are played via the Center, matching it to the front towers is also key, you can reduce db to match but it helps when things are tuned to start with. Polk Audio RTI-A5 towers, CSI-A4 Center, TSI 200 rear surround, PSW125 sub. Thank you bestbuy for unbeatable prices on my surround sound!
