Product Highlights

    Audiophile Performance, Cutting-Edge Stealth Design
    Stacking the woofer behind the driver unit is an innovation so extreme you won't believe the performance that results! Full-size speaker dynamics and a small-diameter cut-out built-in that virtually disappears into your decor. The Vanishing Series puts high performance stealth audio at your fingertips.

Details from Polk Audio

    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.

    Vanishing 700-LS Features:
    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 built-in.

    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 d�cor, Vanishing Series built-in speakers are virtually indistinguishable from their surroundings.

    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 and accurate high frequency response, for no loss of realistic musical details.

    Vanishing Series LS speakers are timbre-matched to Polk LSi speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers.

    If positioning limitations demand that your loudspeakers be installed closer than 2 feet from side walls, the proximity of the surface can result in a response bump between 50 and 200Hz. This can create boomy sound. The Vanishing wall distance toggle switch is a custom audio control that adjusts the crossover to flatten response and tune out boominess, without sacrificing deep bass response, for more lifelike sound and more flexible placement.

    Dual bandpass bass ports are highly efficient in small enclosures, and smoothly funnels the angled woofer's low frequencies down around the driver array, eliminating "chuffing," so your small, practically invisible in-ceiling speakers achieve superior full-range blending and broad coverage with surprisingly deep bass.

    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.
