About Polk Audio 50-RT In-Ceiling Speaker

The Polk Audio 50-RT is the smallest, most "invisible" full-range in-ceiling speaker. It's packed with technology and built with performance in mind. Its lightweight polypropylene cone and sensitive silk dome tweeter can be angled for superior off-axis performance. Plus, its reflective room compensation switch dampens the effect of "reflective" rooms, affording you extraordinary placement flexibility. The innovative addition of the woofer driver behind the main speaker adds unparalleled depth and dynamics to this tiny performer.

Polk Audio 50-RT In-Ceiling Speaker Features

  • The smallest-diameter full-range 3-way driver array means you get full-size speaker performance in a speaker the size of a small inset lighting fixture
  • Extra deep well design with a Cassini oval woofer mounted above and behind the main driver & tweeter array, for broad coverage and dynamic full-range audio performance in a small diameter built-in
  • It features the exclusive wafer-thin Sheer-Grille, a magnetically-secured grille that protrudes only 7mm from its surroundings. Sheer-Grilles have nearly transparent, ultra-small perfs and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms
  • Enhanced, reengineered ring radiator tweeters extend top-end response for incredible details and realistic imaging
  • Reflective surfaces in rooms can make sound brighter and cause image distortion. Engaging the Vanishing reflective room compensation feature (by selecting the low setting) lowers the tweeter level to compensate for reflective surfaces
  • Vanishing reflective room compensation is a custom audio control that cuts the level only in the 4-5kHz range, exactly where reflectivity destroys sound quality
  • Outside this narrow 1kHz band, the tweeter retains its detailed & accurate high frequency response, for no loss of realistic musical details
  • Vanishing Series RT speakers are timbre-matched to Polk RTi speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers
  • PowerPort bass venting is Polk's patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more efficient, deep bass impact
  • Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange and (available) pre-construction brackets; achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system
