Polk Audio has announced the launch of the Polk Reserve Series loudspeakers.

IMAX® Enhanced and Hi-Res Audio Certified and compatible with both Dolby Atmos and DTS:X, the Polk Reserve Series includes nine models available in matte black and matte white finish.

The Reserve Series is suited to a variety of applications, including immersive multi-channel home cinema systems and classic stereo listening. The series consists of nine models, including three floor standing models, three centre channels, two bookshelf speakers and a wall-and speaker-mountable height module, all designed to give listeners flexibility in terms of configuration by incorporating matching transducers and consistent voicing. The centre channel speakers are available in three sizes. The R300 centre channel is designed to fit in most AV cabinets, while the R350 is only 5.5-inches tall, and is wall mountable. For the first time, Polk is introducing a height module (R900), which can be placed on the floor standing speakers or wall mounted. The height module features a toggle switch, which tunes the speaker for the application, whether that be on-speaker or wall mounted.

“The Reserve Series use the same custom-made transducers originally developed for Polk’s Legend Series loudspeakers,” said Frank Sterns, president of Polk Audio.

“While Reserve does use the same transducers as Legend, it also features multiple new developments of its own, including a new patent-pending X-Port filter and advanced cabinet construction to minimize undesirable resonances” said Scott Orth, director of audio and acoustical systems at Polk Audio.

Seeking to retain as much of the Polk Legend flagship performance as possible within a moderately priced package, Polk Audio engineers created rigid, internally braced cabinets while using the driver and port technologies from the Legend Series speakers.

Pinnacle Ring Radiator Tweeters: Decades of tweeter innovation, design and prototyping led to the development of the new 1-inch, high-definition Pinnacle ring radiator tweeter. Developed by Polk Audio, the Pinnacle tweeter features a finely tuned waveguide, which improves the dispersion of high frequency energy, ensuring a broad sweet spot, while the critically damped rear-chamber helps defeat unwanted resonances. A Hi-Res certified driver, the Pinnacle Tweeter is designed for today’s two-channel music listening as well as multi-channel 3D audio found in music, movies, sports, and video games soundtracks.

Turbine Cone Midrange: The Turbine Cone combines Polk’s proprietary foam core driver design with moulded Turbine geometry, which increases stiffness and damping without adding mass.

X-Port Technology: The Reserve Series marks the debut of Polk Audio’s patent-pending X-Port technology, which uses a set of closed-pipe absorbers tuned to eliminate unwanted cabinet and port resonances. X-Port is found on all vented models in the Reserve Series.

Power Port 2.0 Design: Power Port 2.0, found in the R600 and R700 floor standing models, is a Polk-patented loudspeaker port application that enables bass frequencies to extend more deeply and at higher output levels. The Power Port 2.0 combines the new X-Port and Enhanced Power Port design into a unique loudspeaker application. The port tube base was redesigned in aluminium and sits closer to the floor than previous Power Port designs.

Advanced Cabinet Construction: The R700 tower speaker model features advanced point-to-point bracing with new Cabinet Resonance Control technology (CRC) that eliminates panel resonances.
