What Better Sounds Like
The versatile R350 is one of the most unique speakers in the Reserve line because it serves beautifully as a center channel and it can also be used as your left and right channel as needed. Just flip the speaker vertically and you get a multi-transducer Left or Right channel speaker. Since the R350 is wall mountable, you can enjoy flexible placement on any wall.

Hi Res Certified
Your sound is only as good as your source. With Hi-Res Audio certification, the Polk Reserve R350 slim center channel speaker delivers clear and detailed high-end response. Female vocals are particularly smooth and detailed without coloration. Plus, a minimum support of 40kHz perfectly reproduces the soundtracks of the latest Ultra HD movies with improved audio extension.

Fully Sealed Enclosure
Unlike a traditionally ported speaker, the fully sealed design eliminates the turbulence of escaping air to prevent chuffing and other unwanted distortions. You will just get clear, easy to understand dialogue.
REFERENCE QUALITY GOOD

Crystal Clear Vocals for Home Theater
The center channel is the most important speaker in any home theater setup. The Reserve R350 uses Polk’s latest flagship transducer array to deliver clear, crisp, intelligible dialogue no matter where you sit.

Flagship Hi-Res Ring Radiator Tweeter
The Pinnacle Ring Radiator Tweeter’s distinctive pointed shape guides the dispersion of high frequency sounds around a room. This innovation widens the sweet spot and allows you freedom to enjoy your music and movies wherever you choose to sit.

Turbine Cone
Our pioneering turbine design delivers a significant increase in cone rigidity without increasing mass. This innovation means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution, enabling you to experience a breathtaking level of detail in your music and movies.
