Polk Audio® In-Ceiling Loudspeaker-White-70-RT

Polk Audio® In-Ceiling Loudspeaker-White with wafer thin grille and dual band-pass bass ports


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.
  • 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.
  • 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.
