Timbre-matched to the RTiA Series

Sheer-Grille™

The unique, wafer-thin grille is magnetically secured to deliver nearly transparent, ultra-small perfs and dynamic, unimpeded sound.

Power Port®

Patented bass venting design smoothly transitions air flow, eliminating turbulence and distortion, for deeper, more efficient bass impact.

Timbre-Matching

Compatible with Polk Audio RTi speakers for seamless blending between traditional and built-in speaker systems.

Reflective Room Compensation

Lower tweeter levels offset reflective surfaces, cutting the level in the exact 4-5kHz band where reflectivity destroys sound quality.

Distance Toggle

Crossover adjustments flatten response bumps caused by nearby walls, reducing “boominess” for more lifelike sound from any position.

Simple Setup

Perfect Fit templates, a precision flange, available pre-construction brackets and the patented Rotating Cam system ensure secure, vibration-free installation.
