What Better Sounds Like

As we get older, we learn what better looks like, feels like, tastes like and even drives like. But nobody teaches us what better sounds like. Better isn’t best – it’s the road to best.

Crystal Clear Vocals for Home Theater

The center channel is the most important speaker in any home theater setup. The Reserve R300 uses Polk’s latest flagship transducer array to deliver clear, crisp, intelligible dialogue no matter where you sit.

Flagship Hi-Res Ring Radiator Tweeter

Over 40 years of tweeter innovation, design and prototyping has led to the development of the new 1” high definition Pinnacle ring radiator tweeter. Developed by Polk Audio, it delivers ultra-clear, crisp highs without unwanted coloration or distortions. The Pinnacle tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy ensuring a broad “sweet spot” while the critically damped rear-chamber helps defeat any unwanted resonances. Hi-Res certified, the Pinnacle Tweeter is designed for today’s two-channel music listening as well as multi-channel 3D audio found in movies, sports, and video game soundtracks.

Turbine Cone

Polk developed the Turbine cone specifically for our flagship products to ensure the natural reproduction of the mid-range, to which human ears are particularly sensitive. The Turbine cone combines Polk’s proprietary foam core and molded Turbine geometry which dramatically increases stiffness and damping, without adding mass. With four 4” Turbine woofers, you will hear every detail and experience smooth, detailed mid-range and effortless bass.

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 latest Hi-Res Audio files 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.
