  • Polk’s exclusive dynamic sonic engine design optimizes the midrange driver and the ring radiator tweeter in separate interior chambers for improved transient response, superior imaging and greater horizontal off-axis response.

  • Enhanced, reengineered ring radiator tweeters extend top-end response for incredible details and realistic imaging.

  • Newly designed Cassini oval subwoofer drivers, with more surface area than round drivers, dramatically improve low-frequency response for deep, well-blended bass.

  • Our innovative overhung voice coil design augments the excursion length for subwoofer drivers, increasing their power-handling capabilities and enhancing bass response.

  • Extended Linear Motion voice coil design allows lots of movement in a limited space, eliminating impedance and extending mid- and high-frequency response.

  • Lightweight, rigid cast aluminum baskets are designed for precision motor alignment withunobstructed linear movement and ample venting.

  • Klippel motor optimization uses laser measurement technology to ensure a smooth excursion path at either end of the volume spectrum for uniform performance at both low and high volumes.

  • Polk’s proprietary, patented Dynamic Balance® technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.

  • Our super cell aerated polypropylene cone is the ideal balance of lightweight stiffness (for more efficient action with less distortion-causing flex) and superior damping properties.

  • Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.

  • Exclusive, patented Orth crossovers increase lower-order power handling and smooth the impedance curve, for more efficiency and better high frequency response.

  • High quality, heavy duty LSiM enclosure construction features 1.0" MDF on the sides, 3/4" MDF on the back and bottom and 1 1/4" baffles with substantial internal bracing and separate interior cabinetry for each driver. These exceptionally robust materials efficiently eliminate cabinet resonances and standing waves for less distortion and more dynamic transparency.

  • Beautiful furniture-grade hardwood veneer cabinet finishes, with sleek trim accents and no visible screws.

  • Super-thin zero-diffraction grilles lock in place magnetically, and never obscure your sound.

  • PowerPort® bass venting is Polk’s patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more efficient, deep bass impact.

  • All Polk loudspeakers are timbre-matched within their series, designed with the same components throughout, to achieve seamless speaker-to-speaker blending effects in multi-channel systems.

  • Dual gold-plated, professional-style 5-way binding posts, for the most secure connection options.

  • Dual binding posts allow bi-amp or bi-wire connections, for the ultimate in customized high performance audio.

  • Innovative no-tip hex-head floor spikes make speaker-leveling easy on any flooring.
