Why the Reserve Series

Polk Reserve is a premium loudspeaker series that incorporates the custom transducers from Polk’s flagship Legend series alongside new Polk innovations in cabinet and port design to deliver flagship music and movie sound without flagship prices. It is Dolby Atmos and DTS:X compatible and certified for Hi-Res Audio.

Pinnacle Ring Radiator Tweeter

Born of 50 years of speaker engineering, the Pinnacle Ring Radiator Tweeter features a finely tuned waveguide that dramatically improves the dispersion of high-frequency energy, ensuring a broad sweet spot and consistent sound in every listening position. Hi-Res certified, the Pinnacle Tweeter is designed for today’s two-channel music listening as well as multichannel 3D audio found in movies, sports, and video game soundtracks.

Turbine Cone

The Polk-designed Turbine Cone is a foam-core, injection-molded cone made of polypropylene with turbine geometry that dramatically increases stiffness and damping without adding mass. This results in a smooth, detailed mid-range with three-dimensional imaging that brings music and movies to live.

Polk Patented X-Ports

Featuring an Eigentone Filter (ETF), Polk’s newly patented X-Port consists of a set of closed-pipe absorbers specifically tuned to dramatically reduce traditional speaker distortions, creating deep, effortless bass. This ensures that the upper bass and mid-range are free of port and cabinet resonances for clear, smooth, and detailed sound.

Hi-Res Audio Certified

Hi-Res Audio files deliver sound with quality superior to that of CDs. For a loudspeaker to qualify for the Hi-Res certified badge, it must be able to play up to 40 kHz. Reserve speakers meet these requirements, ensuring all the high-resolution detail delivered from the amplifier is played back faithfully by the speaker.

Detailed Imaging & Soundstage

Driven by the Reserve’s proprietary technologies, the series delivers exquisitely balanced, dynamic, and detailed sound every time.

IMAX Enhanced Certified

During the development of the Legend series, Polk helped the team at IMAX create the IMAX Enhanced loudspeaker specification, ensuring that only the highest-performance home theater speakers would qualify. The Reserve series’ IMAX enhanced certification guarantees an unforgettably huge and dynamic home theater experience when enjoying IMAX Enhanced movies, TV shows, and music.

Dolby Atmos and DTS:X Compatible

The Polk Reserve series is compatible with both Dolby Atmos- and DTS:X-enabled A/V receivers and pre-amp processors as well as Dolby Atmos and DTS:X virtualizers.

Timbre-Matched Configurability

Mix and match Reserve speakers to fit most rooms and configurations without concern. The Reserve series guarantees great, timbre-matched sound in any configuration.

Traditional Home Theater

Step up to dynamic, detailed home theater. Choose the Reserve series configuration that matches your room’s needs, and add an optional HTS series subwoofer to provide even more bass.

Atmos & IMAX

The Reserve series is IMAX certified and compatible with Dolby Atmos, DTS:X, and Auro 3D home theater technologies. Adding the optional Reserve 900HT height modules to your Reserve home theater means your movie room is ready for anything, including the most dynamic 3D audio movie mixes available.
