About the Polk Audio 620-RT
Your home theater proposal got the "green light" but free-standing surround speakers were given the kibosh by a major stakeholder. Don't despair. Grab a pair of the Polk Audio 620-RT speakers. They install discreetly overhead, so you can keep your surround sound speakers out of sight or add music to rooms where conventional speakers just won't cut it.
Great quality + a vanishing profile = consensus
The 620-RT speakers uses a 6-1/2" woofer and a 3/4" pivoting silk-polymer dome tweeter for outstanding lifelike sound. Polk's patented port design delivers full range so you'll sacrifice nothing but an obtrusive outline. Paintable magnetic speaker grilles fit flush in the ceiling. The only time you'll be aware of these 'RTs is when you hear the whoosh of a jet engine overhead or shouts from behind you from a favorite film soundtrack.
Might as well invite the whole family over
Complete your system with other members of Polk's Vanishing RT series of speakers. You may also want to peruse their renowned, sonically matching RTi speakers. Build a home theater that will thrill and delight for years to come.

Vanishing Series In-Ceiling Loudspeakers: The Polk Audio Vanishing Series 620-RT in-ceiling loudspeaker features a precision-engineered, minimally flanged design. Polk's exclusive Sheer-Grille protrudes only 7mm from its surroundings, and installs virtually-flush in your ceiling. Mounting the speaker is simple with a one-cut, drop-in installation and the rotating cam stabilizing system. The speaker provides superior high-performance sound from its 6.5" woofer and aimable 0.75" tweeter with Reflective Room Compensation control.
Dynamic Balance Technology: Laser-imaging technology allows Polk Audio engineers to see the entire vibrating surface of a driver and tweeter. This allows the engineers to actually see performance-robbing distortion develop on the speaker cone. Using this data, they can determine the Dynamic Balance of their high-tech materials, and alter the geometry and construction of the speaker to effectively tune out the offending resonance. Exclusive Dynamic Balance Composite Material Technology delivers sound that is effortlessly clean and clear, even at lifelike volume levels.
Klippel Optimized Motor Structures: The Klippel Distortion Analyzer allows Polk engineers to optimize each driver's motor structure, voice coil alignment and suspension to insure smooth, unimpeded movement even at extreme listening levels. This is especially important in the shallow depth area afforded an in-ceiling loudspeaker.
Polymer Composite Woofer: The 620-RT in-ceiling loudspeaker employs a 6.5" Dynamic Balance polymer composite cone woofer with a rubber surround for a smooth, consistent frequency response. The driver features a lightweight, strong composite basket that works in conjunction with Klippel Optimization to keep moving parts in rigid alignment while further damping performance-robbing resonances.
Silk Dome Tweeter: The speaker employs a 0.75" Dynamic Balance silk polymer composite dome tweeter for crisp, clear imaging. The high-performance tweeter features a 15° swivel housing, for more direct high frequency control, excellent off-axis imaging and more placement flexibility.
Timbre-Matched: The Polk Audio Vanishing Series in-ceiling loudspeakers are timbre-matched to Polk Audio's high-performance RTi bookshelf and floor-standing loudspeakers. This allows you to match them to an existing Polk Audio home theater speaker system and enjoy seamless blending from speaker to speaker. Timbre-matched speaker components will insure the same true response throughout your system.
Frequency Response: The overall frequency response of the in-ceiling speaker is 35Hz to 25kHz, and the -3dB frequency response is 52 to 23kHz.
Infinite Baffle Tuning: Infinite Baffle Tuning uses the virtual enclosure of the in-ceiling space for deep bass response and superior overall sound.
Wafer-Thin Sheer-Grille: The Polk Audio Vanishing Series in-ceiling speakers feature Polk's exclusive wafer-thin Sheer-Grille, a magnetically secured grille that protrudes only 7mm from its surroundings. The Sheer-Grille can be painted to match your décor, making it virtually indistinguishable from its surroundings. The Sheer-Grille has nearly transparent, ultra-small perfs, and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms.
Note: When painting the grille, it is highly recommend that you use a can of spray paint matched to the color of the surrounding ceiling. Brushes or rollers should not be used to paint the grille, as this will clog the perf holes.
Gold-Plated Spring-Loaded Posts: The 620-RT has a pair of gold-plated spring-loaded binding posts that can accept single banana plugs, pin connectors, or bare wire up to 12-gauge.
Applications: You can use the Polk Audio Vanishing Series in-ceiling loudspeaker as in-ceiling rear surrounds to complete an RTi Series speaker system, or for superior dynamics in practically invisible multi-zone music systems.
Rotating Cam System: The speaker utilizes a rotating cam system to ensure a secure, vibration-free installation. There are six rotating cams to hold the speaker securely to the ceiling.
Installation: The 620-RT can be installed in new or existing construction:
- Existing Construction: In existing ceilings, use the included cardboard template for one-cut, drop-in simplicity.
- New Construction: Pre-construction brackets (sold separately) are available for new-build or open-ceiling retro-fitting.
