It is a Full-range, Bandpass, Dual-port 3-Way in-ceiling loudspeaker features the exclusive wafer-thin Sheer-Grille, a magnetically secured grille that protrudes only 7 mm from its surroundings. Sheer-Grilles have nearly transparent, ultra-small perfs and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms. Reflective surfaces in rooms can make sound brighter and cause image distortion. Engaging the Vanishing reflective room compensation feature (by selecting the low setting) lowers the tweeter level to compensate for reflective surfaces. Vanishing reflective room compensation is a custom audio control that cuts the level only in the 4-5 kHz range, exactly where reflectivity destroys sound quality. Outside this narrow 1 kHz band, the tweeter retains its detailed and accurate high frequency response, for no loss of realistic musical details.
- The smallest-diameter full-range 3-way driver array delivers full-size speaker performance in a speaker the size of a small inset lighting fixture

- Enhanced, reengineered ring radiator tweeters extend top-end response for incredible details and realistic imaging
- Vanishing wall distance toggle switch is a custom audio control that adjusts the crossover to flatten response and tune out boominess, without sacrificing deep bass response, for more lifelike sound and more flexible placement
- 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
