Incredible sound from this unit. I have this hooked up to an Onkyo 606 RTiA3, in front and some cheap Pioneer cubes as rears(for now) and a Martin Logan Dynamo sub. Get compliments from everyone that comes here. The A4 is one of the more amazing sounding unit I have seen. I have had this unit for about a year and a half and I couldn't be happier.

this is a very good center for the buck...cant beat polk for value the highs are nice and crisp, good punch at the low end ... I have the csi a4, with RT 1000P front,FX 300 at the rare, and cs175 as back surrounds.

I absolutely LOVE my new center channel. I intend to upgrade to all RTi speakers. There is a level of clarity and detail that I didn't have before. And, the bass response REALLY surprised me!

Just bought this speaker to go along with my 5.1 system and is excellent. Great design matches the rest of my system and the sound is superior to all previous center channels i have owned. Great speaker

Excellent sound, in both music and movies. It is working with a Yamaha receiver RX-V861,a pari of Monitor 60 (Tower, a set of FXi-A4 and Velodyne DLS-R3750 subwoofer. I read in some bad reviews about CSi3 related to music performance. This unit sound great in both. The dynamic range is deep and the balance between bass and treble is ok. Stylized line.

I have this with a pair LC65i and a pair of TC65i. The center channel has better bass than I thought. And it sounds far better then my Kliptch system. I use a Pioneer VST81 receiver and a Polk 12' Sub. The system center pieced by the A4 sounds awesome... I'm a Polk fan for life.

The High Performance Heart of Home Theater
The CSiA4 is a high performance center channel speaker for smaller rooms and challenging placement situations. It features two 5 1/4-inch Dynamic Balance drivers, one 1-inch Dynamic Balance dome tweeter for spot-on imaging, seamless soundstage and natural sounding voices. With the asymmetric cabinet design, you gain the flexibility to placing the CSiA4 above or below the TV and aim it at your position.
CSiA4 Features
The proprietary curved, 6-layer DAHLI enclosure design creates the optimal shear damping for a more rigid, acoustically inert enclosure and minimal cabinet resonances. CSiA4 cabinets are designed for clean, accurate sound
Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes
Polk's proprietary, patented Dynamic Balance technology allows their engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds
Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound
The RTiA Cascade Tapered Crossover eliminates the comb filtering and beaming, common to multi-driver speakers, which degrades the quality of the audio and collapses the soundstage
Patented Acoustic Resonance Control (ARC) technology suppresses cabinet resonance that causes distortion to ensure clear and natural sound
Beautiful curved furniture-grade hardwood veneer cabinet finishes, with sleek trim accents in black or cherry
Computer-modeled anti-diffraction grilles enhance the good looks while minimizing sonic interference
All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems
Gold-plated, professional-style 5-way binding posts, for the most secure connection options
