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.

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 their 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.

Compact and high performance center channel for reserve series.
I use this as a center channel for a pair of Polk reserve 600s, and they all sound wonderful together. I chose it due to the size of the R400 getting difficult to place due to its physical size and rear ported design probably requiring more space behind its larger cabinet. This sealed R300 is still fairly large, but sits comfortably where I needed it to go. It also blends very well with the R600s despite the smaller woofer. If you don't have the space for the R400, I would consider this a viable option for pairing with the R600 or the R700 towers.
