Polk Audio announced the launch of the Reserve Series, a loudspeaker line designed for immersive multichannel home theater systems and classic stereo listening. The series consists of nine models, including three floor-standing models, three center 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 center channel speakers are available in three sizes. The R300 center channel is designed to fit in most AV cabinets, while the R350 is only 5.5 inches tall, and is wall mountable so it can be used as left, right or center channel. 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.

Polk Audio engineers created rigid, internally braced cabinets while leveraging driver and port technologies from the Legend Series speakers to achieve breathtaking levels of balance and realism.

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.

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

The Reserve Series marks the debut of Polk Audio’s patent-pending X-Port technology, which uses a set of closed-pipe absorbers precisely tuned to eliminate unwanted cabinet and port resonances. X-Port is most beneficial to the lower mid-range, ensuring balanced, clean mid-bass. X-Port is found on all vented models in the Reserve Series.

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 than traditional ported speakers. 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 aluminum and sits closer to the floor than previous Power Port designs for added performance characteristics and aesthetics.

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