The highest performance Polk Audio in-wall loudspeakers are now even more invisible with magnetically-secured, minimal flange, Sheer-Grilles™ for completely stealth high-end audio installations. All new drive units, crossovers and improved PowerPort® in many models update the performance to even higher standards. All you hear is great sound. All you see is…your paint color.

Audiophile Performance, Cutting-edge Stealth Design

Mount your woofer behind your main driver array, and suddenly you’re able to extend a speaker’s dynamic range into previously unexplored areas! Especially for a built-in in-ceiling speaker. The 900-LS delivers surpisingly broad coverage and bold, full-range audio performance. Big enough to use as stealth mains, stealthy enough to use as hidden surrounds or alternate-zone speakers.

Vanishing 900-LS Features:

The full-range 3-way driver array means you get full-size speaker performance in a built-in!

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.

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 décor, 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.

AMAZING BASS RESPONSE

- 4/13/2014

Every time I turn these on I can't believe the bass response i get from them. Dave wasn't kidding when he said to get these if I wanted to " Rock the house " thanks dave for the recommendation!
