The distinctive Pinnacle Ring Radiator tweeter with its pointed waveguide ensures high frequencies are distributed evenly around the room, widening the sweet spot and providing an incredibly lifelike soundstage no matter where you sit. Hi-Res Audio Certified, you’ll hear music and movies, breathtakingly detailed, with an airy high end unlike anything you’ve experienced before.
Polk’s pioneering Turbine Cone woofer features unique molded ridges that increase cone rigidity without adding mass. This innovation means the woofer can move with increased accuracy and speed to deliver enhanced sound resolution, enabling you to experience a smooth, detailed midrange with dazzling dimensionality.
Polk’s patented Power Port tames unruly air turbulence, for smooth, clean bass without extraneous noise and distortion that can mask the clarity of midrange sounds. Put simply, it delivers deep low-end impact while revealing vocals and instruments in all of their exquisite detail. Select Reserve models also incorporate our patented X-Port which adds precisely tuned pipe absorbers and Eigentone Filters (ETF) to further reduce resonances and distortion.
Some of the most profound sonic innovations are the ones you can’t see. Reserve’s thoughtfully engineered cabinets feature strategically angled bracing—just like the walls you’d see in a concert hall or professional recording studio—to break up sound wave paths and eliminate resonances for smooth, peak-free response with open, uncolored bass and midrange.
