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.

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.

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.

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 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.

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.

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

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

Designed for dynamic two-channel listening, the Reserve series speakers' precise imaging, multidimensional soundstage, deep bass extension, and Hi-Res certification ensure a faithful reproduction of your favorite music.

The R200 bookshelf speakers in your office or den transform your casual listening environment to a private concert in your home.

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.

The R200 is compatible with Dolby Atmos, DTS:X, and Auro 3D home theater technologies. Adding the optional Reserve 900HT height modules to your Reserve system means your movie room is ready for anything, including the most dynamic 3D audio movie mixes available.
