Polk Audio® 5.25" In-Wall Center Channel Speaker-White-255c-RT

Polk Audio® 5.25" In-Wall Center Channel Speaker-White with wafer thin grille and patented bass venting design


The Vanishing Series 255c-RT is the centerpiece of a world-class stealth home theater. Paintable to match any dcor, this in-wall center channel speaker blends in perfectly with its surroundings. Anchoring all the action without attracting attention, the 255c-RT ensures all you see is screen, and all you hear is dynamic, crystal clear sound.
  • 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.
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.
