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.Read More
Broad coverage and dynamic, full-range performance from an extra deep well design with a Cassini oval woofer
Painted to match your décor, Vanishing Series built-in speakers blend in perfectly with their surroundings
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.
Smooth funneling for low frequencies around the driver array eliminates “chuffing” for full-range blending, broad coverage and deep bass.
Perfect Fit templates, a precision flange, (available) pre-construction brackets and the patented Rotating Cam system ensure secure, vibration-free installation.
