Innovation and invisibility.

A mid-sized powerhouse of audio technology you will barely see, but you’ll certainly hear. Slightly larger diameter gives you the flexibility use this practically invisible speaker in more intense applications, as side or rear surround speakers in your home theater, for instance. Featuring the ultra-responsive and detailed Ring Radiator Tweeter, found only on true audiophile loudspeakers (and never in compact built-in speakers!), this in-ceiling speaker disappears into any d cor, without sacrificing the performance you demand. The space-saving rear-mounted oval woofer, combined with built-in Dual Bandpass Porting, adds deep bass to a colorful full-range palette.

  • Full-Range 3-Way Driver Array in the Smallest Diameter Innovative new patent-pending design! It’s like having a full-range, full-size speaker in a small inset lighting fixture. Adding a woofer for low frequency response frees up the midrange and tweeter for more efficient detail. To do it, we designed a deep well and mounted the Cassini oval woofer above and behind the main driver array. This innovative deep diagonal positioning allows the 50-RT cutout to be just 6" in diameter. This full-range 3-way driver array results in the kind of broad coverage and big performance usually achieved only with… bigger speakers!
  • 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 d cor, Vanishing Series Built-In 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.
  • 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.
  • Dual Bandpass Bass Ports Bandpass Ports are the way to go when you want high efficiency in small enclosures. Each Vanishing In-Ceiling Speaker sports dual Bandpass Bass Ports, smoothly funneling the angled woofer’s detailed low-frequencies down around the midrange and tweeter array. The port design eliminates “chuffing,” so your small, practically invisible in-ceiling speakers achieve superior full-range blending and broad coverage with surprisingly deep bass.
  • Easy Installation Puts the architectural elegance of “invisible” speakers within reach for anyone. In existing closed ceilings, use the Perfect Fit Template for one-cut, pop-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-ceiling retro-fitting. Our precision-engineered minimally flanged design lets you get professional results with no additional drywall work.
