Practically Invisible In-Ceiling Loudspeaker
To perform well with a budget in mind is to perform well, indeed. This practically invisible in-ceiling speaker is your introduction to the world of stealth audio; with superior components for performance, the critics consider top-flight in its class.
Built to satisfy the need for clutter-free audio, interior design savvy and audiophile performance standards, Vanishing® RT speakers are the best sounding entry-level in-ceiling & in-wall speakers Polk has ever made.
Superior imaging and clear, lifelike detail is revealed by the responsive silk dome tweeter in Vanishing RT speakers; it’s set in a 15-degree swivel housing, for more direct high frequency control, excellent off-axis imaging and more placement flexibility.
Vanishing Series built-in speakers feature our 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.
Painted to match your decor, Vanishing Series built-in speakers are virtually indistinguishable from their surroundings.
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.
All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.
