Polk Audio 700-LS 7” Vanishing Series 3-Way In-Ceiling Loudspeaker Cutting-edge design with audiophile performance never sounded so good. With the Polk Audio 700-LS, broad coverage and bold full-range audio is a breeze. It’s big enough to use as stealth mains, and steady enough to use as hidden surrounds or alternate-zone speakers. Big Sound Full-size speaker performance is built into the 7” Vanishing Series 3-Way In-Ceiling Loudspeaker. It features a unique 3-way driver array with an extra deep well design, this is enhanced by a Cassini oval woofer mounted above and behind the main drive and tweeter array, allowing broad coverage with dynamic performance all from a small built-in. A Perfect Match Made to match the style and décor of their surroundings, the Polk Audio 700-LS fits any setting. Its wafer-thin painted grille magnetically secures to deliver a transparent dynamic with unimpeded sound. Features This Loudspeaker is timbre-matched to Polk LSi speakers to ensure seamless speaker-to-speaker blending for systems that combine traditional and built-in speakers. Lower tweeter levels also offset reflective surfaces to cut the level in the exact 4-5kHz band where reflectivity destroys sound quality. Vanishing Wall Positioning limitations are no longer an issue with this loudspeaker. 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. Rich lifelike sound is the result with more flexible placement. Dual Band-Pass Bass Ports Eliminate “chuffing” for full range blending with broad coverage and deep bass. The Polk Audio 700-LS does this by utilizing smooth funneling for low frequencies around the driver array. Easy to Install Perfect fit templates are included along with a precision flange, (available) pre-construction brackets and a patented Rotating Cam. All of this comes together to offer secure, vibration-free installations.
