Manual/Downloads

Surprisingly Big Sound

The Vanishing® Series 70-RT features a unique 3-way driver array that produces big, full-range performance from a deceptively small in-ceiling speaker.

Key Technologies

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.

Dual Band-Pass Bass Ports

Smooth funneling for low frequencies around the driver array eliminates “chuffing” for full-range blending, broad coverage and deep bass.

Simple Setup

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