Life is good. You got the better house. The better furniture. The better car. But, why haven’t you gotten better speakers yet?

With understated elegance, the Reserve line has a minimalist design with universal appeal. Inheriting Polk’s flagship transducer array, the speakers produce exceptional sound rivalling competitor speakers that sell for twice the price. Immerse yourself in your favourite musical recordings or your weekly movie night with the new Polk Reserve.


The Most Important Speaker in Your Home Theatre

The center channel is the most important speaker in a home theatre set up and the R400 delivers crisp and easy to understand dialogue for all your favourite movies and shows. With dual 6.5” Turbine cones and 1” Pinnacle tweeter, the R400 offers serious home entertainment impact.


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 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.


6.5” 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.


Polk Newly Patented X-Port (ETF)

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.


Sleek Modern Design

The Reserve R400 center channel speaker is available in Midnight Black.


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.
