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 Voice of Your Home Theatre

The center channel speaker plays a critical role in a multi-channel system and the R350 can be the perfect “voice” for your home theatre. You will enjoy crystal-clear audio and dynamic audio from any seat in the room.

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.

4” 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.

Sleek Modern Design

The Reserve R350 center channel speaker is available in two modern finishes: Midnight Black and Satin White (coming mid 2021).

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.

The Ultimate Front Stage

The versatile R350 is one of the most unique speakers in the Reserve line because it serves beautifully as a center channel and it can also be used as your left and right channel as needed. Just flip the speaker vertically and you get a multi-transducer Left or Right channel speaker. Since the R350 is wall mountable, you can enjoy flexible placement on any front or rear wall.
