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.

X-Port

Polk’s newly patented X-Port incorporates an Eigentone Filter (ETF) offering distortion-free, effortless bass. Consisting of a set of closed-pipe absorbers that are specifically tuned to catch and eliminate traditional speaker distortions. X-Port ensures that the upper bass and mid-range are free of port and cabinet resonances for smooth, detailed audio.

Built for performance

Polk’s goal since our founding has been to build great loudspeakers that virtually transport the listener’s room into the scene of the recorded performance. To meet this challenge, Polk engineers and designers constantly innovate and painstakingly improve every detail. Nothing is left to chance and nothing unnecessary is ever added. The results are best-in-class loudspeakers that outperform the competition for half the price, earning numerous awards, patents, and most importantly Polk speaker owners that swear by the brand. Don’t take our word for it – go listen.
