For the biggest full range dynamic audio, with no visible speaker boxes, you need the power and potential of an in-wall 3-way speaker that includes Polk's patented PowerPort bass venting system. Easy to install, you can build a complete high performance audio system that blends seamlessly into your décor. Tailor the performance to suit your room environment with superior audio controls to guarantee the most spectacular sound. At this level, Vanishing LS is the best value in today's hottest style of custom-installed loudspeaker.

• Practically Invisible Grilles And Minimal Flanges-New design! No other moderately-priced built-in speaker is this invisible. Vanishing Series Built-In Speakers feature our exclusive wafer-thin Sheer-Grille, a magnetically-secured grille that protrudes only 7mm from its surroundings. That's just this much ----. Painted to match your décor, Vanishing Series in-ceiling & in-wall speakers are virtually indistinguishable from their 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.
• Timbre-Matched to Polk Audio LSi Speakers Match Vanishing LS speakers to our flagship LSi Series Loudspeakers. Timbre-matching with the same internal components, and same lightweight Aerated Polypropylene Cone material, insures utterly seamless blending from speaker to speaker. Use Vanishing Series Speakers to build a system or complete an existing LSi system.
• High Performance Tweeters- Superior imaging and clear, lifelike detail is revealed by superior tweeter technology. Vanishing LS speakers are the only built-ins to feature the ultra-high-performance Ring Radiator Tweeter used in our highest-end freestanding loudspeakers. The Reflective Room (Tweeter) Compensation Switch digitally compensates for reflective rooms without hindering high performance, for extraordinary placement flexibility.
• Customizable Wall Distance Setting Tailors frequency response for optimum performance regardless of room shape. Ignore the usual performance-robbing suspects of corners and adjacent wall surfaces! The Wall Distance Setting gives you the power to defeat "boominess," even in close quarters, leaving dynamic response intact.
• PowerPort Bass Venting Patented PowerPort Bass Venting smooths turbulence at the mouth of the port, especially important in shallow-depth installations, and ensures the seamless speaker-to-subwoofer blending with smoothest bass response possible.
• Easy Installation Puts the architectural elegance of "invisible" speakers within reach for anyone. In existing walls, use the Perfect Fit Template for one-cut, drop-in simplicity. Achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system. Pre-construction brackets are available for new-build or open-wall retro-fitting. Our precision-engineered minimally flanged design lets you get professional results with no additional drywall work.
