Vanishing Series In-Wall Speakers: The Polk Audio Vanishing Series in-wall loudspeakers feature a precision-engineered, minimally flanged design and Polk's exclusive Sheer-Grille, which protrudes only 7mm from its surroundings. Installing virtually flush in your wall, the Polk Audio Vanishing Series in-wall loudspeakers offer a one-cut, drop-in installation and rotating cam stabilizing system. The Vanishing LS series in-wall speakers are timbre-matched to Polk Audio's flagship LSi and LSiM series loudspeakers for seamless blending from speaker to speaker when you're building a speaker system.
Dual Midranges: This Polk Audio Vanishing Series 255c-LS in-wall center-channel loudspeaker employs two 5-1/4" Dynamic Balance aerated polypropylene cone midrange drivers with rubber surrounds for a smooth, consistent frequency response. The aerated polypropylene cones are 20% lighter than conventional polypropylene, and 35% lighter than aluminum, to give you clear midrange, punchy bass, and high efficiency. Polk Audio's patented Dynamic Balance technology eliminates unwanted resonances.
Ring Radiator Tweeter: The 255c-LS employs a 1" Dynamic Balance ring radiator tweeter for detailed highs and superb imaging. This high-performance tweeter features a 15° swivel housing, for more direct high frequency control, excellent off-axis imaging and more placement flexibility.
Reflective Room Compensation Control: The Reflective Room Compensation Switch, conveniently located on the front panel, allows you to digitally compensate for harsh reflective surfaces, such as smooth walls, glass windows, and hardwood floors. The filter doesn't merely reduce high frequencies, it simply cuts the level only in the 4-5kHz range where room acoustics most often interfere with performance. The switch is labeled "Tweeter" with two positions: out (normal) and in (filter).
Frequency Response: The overall frequency response of the in-wall center-channel loudspeaker is 30Hz to 33kHz, and the -3dB frequency response is 44 to 29kHz.
Sheer-Grille: The 255c-LS features Polk Audio's exclusive wafer-thin Sheer-Grille, a magnetically-secured metal 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 perforations, and is acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms. The grille's dimensions are 14-3/4" x 9-1/4".
Gold-Plated Spring-Loaded Posts: The in-wall center-channel loudspeaker has a gold-plated pair of spring-loaded binding posts that can accept up to 12-gauge wire, single- or dual-banana plugs, or pin connectors.
Applications: You can use the Polk Audio Vanishing Series 255c-LS in-wall center-channel loudspeaker to complete a system of traditional loudspeakers or in-wall speakers, by adding an inconspicuous center-channel speaker.
Note: The speaker isn't recommended for installation in high-moisture locations.
Placement: The in-wall center-channel speaker is designed to be installed above or below your flat-panel television. It should be installed as close to ear level as possible. If the speaker needs to be installed lower or higher than ear level, you should aim the tweeter accordingly.
Note: Do not block the in-wall center-channel speaker with your TV or furniture, as this will disrupt and muffle the sound.
Rotating Cam System: The Polk Audio in-wall center-channel loudspeaker utilizes a rotating cam system to ensure a secure, vibration-free installation. The 255c-LS has 6 rotating cams to hold the speaker in place. The cams can be tightened from the front panel with a Phillips-head screwdriver.
