Key Features

The Polk Reserve R300 is built with premium technologies to ensure outstanding clarity and performance in a compact center channel design. At its core is the Pinnacle Ring Radiator tweeter, which enhances high-frequency dispersion for clear, crisp, and natural highs. Dual Turbine Cone woofers deliver smooth, highly detailed midrange imaging, making dialogue and vocals sound lifelike and engaging.

The fully sealed speaker enclosure eliminates distortion and port noise, resulting in clean, intelligible sound even in confined spaces. Anti-diffraction magnetic grilles maintain acoustic transparency while offering a sleek, modern look. For optimal performance, Polk recommends 70 watts or more of amplification per channel. Premium, large 5-way binding posts ensure easy setup and a direct, efficient signal path for lossless audio reproduction.

Crisp dialogue to your home theater

At only 19” wide, the Polk Reserve R300 compact center channel fits beautifully into any home theater set up. With a 1” Pinnacle tweeter and dual 5.25” Turbine woofers, you will enjoy crisp, clear vocals and intelligible dialogue for your favorite movies and shows.

High Definition Pinnacle 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 Audio 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.

5.25” 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. You will hear every detail and experience a smooth, detailed mid-range and effortless bass.

Power for the Best Performance

70W or more per channel power amplification is recommended to experience the best sound quality and performance.

Crystal Clear Vocals For Your 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.

Cabinets Built for Better Performance

Polk believes cabinets should be beautiful and add nothing to the playback. Polk Reserve cabinets, braces, and internal enclosures are carefully engineered to minimize unwanted internal standing waves and eliminate unwanted resonances. The result is a cabinet that rigidly holds the transducer array while it faithfully reproduces recordings.
