The Basics

Model #: 70-RT
Measurements: Approx. 8.13" Diameter
Weight: Approx. 8 lbs
Country of Origin: China


  • 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
