High performance audio from an in-wall center speaker designed for a flush fit with your wall
Silk dome tweeters set in a 15° swivel housing provide direct high frequency control, excellent off-axis imaging and more placement flexibility
Innovative features and patented Polk Audio technology in a discrete, easy-to-install package
Timbre-matched to the RTiA Series
The unique, wafer-thin grille is magnetically secured to deliver nearly transparent, ultra-small perfs and dynamic, unimpeded sound.
Patented bass venting design smoothly transitions air flow, eliminating turbulence and distortion, for deeper, more efficient bass impact.
Compatible with Polk Audio RTi speakers for seamless blending between traditional and built-in speaker systems.
Lower tweeter levels offset reflective surfaces, cutting the level in the exact 4-5kHz band where reflectivity destroys sound quality.
Crossover adjustments flatten response bumps caused by nearby walls, reducing “boominess” for more lifelike sound from any position.
Perfect Fit templates, a precision flange, available pre-construction brackets and the patented Rotating Cam system ensure secure, vibration-free installation.
