POLK AUDIO RESERVE R700
FLAGSHIP FLOORSTANDING LOUDSPEAKER
The R700 offers uncompromising sonic performance. This full throttle loudspeaker adds two 8” woofers to deliver massive impact with striking audio clarity and detail. Perfect for use as a reference stereo pair or as the cornerstone of the ultimate home cinema.
FLAGSHIP POLK SOUND
The Reserve Series incorporates groundbreaking Polk technologies found on our award-winning Legend Series to bring its flagship sound to more people.
PINNACLE RING RADIATOR TWEETER
The Pinnacle Ring Radiator Tweeter’s distinctive pointed shape guides the dispersion of high frequency sounds around a room. This innovation widens the sweet spot and allows you freedom to enjoy your music and movies wherever you choose to sit.
TURBINE CONE WOOFER
Our pioneering turbine design delivers a significant increase in cone rigidity without increasing mass. This innovation means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution, enabling you to experience a breathtaking level of detail in your music and movies.
OPTIONAL HEIGHT MODULE
For immersive vertical sound, add compatible Reserve R900 height modules (sold separately). These optional height modules perform beautifully with the latest home theater technologies, including: Dolby Atmos, DTS, DTS:X, DTS:X Virtual, IMAX Enhanced, and Auro-3D.
POWER PORT 2.0
Polk’s new Power Port 2.0 is the latest version of our successful Power Port technology. In addition to Power Port’s carefully engineered port design that smooths the flow of air as it exits the cabinet through the port, X-Port adds a set of closed-pipe absorbers that are specifically tuned to unwanted cabinet and port resonances. Together, these two technologies combine to function as Power Port 2.0 to deliver smooth, detailed audio. Combined with dual 8” woofers, you’ll get louder, cleaner bass while minimizing turbulence and port noise.
EXCEPTIONAL CABINETRY
Reserve’s sleek cabinetry hides a world of audio innovation. Cabinets are carefully cross-braced to best eliminate unwanted interior resonances. Rounded exterior corners help disperse sound broadly around the room with minimal diffraction, creating an open sound stage.
