They focused your attention using a bright, otherworldly light. Even in their most intimate portraits, the riveting light draws your eye.\u003cbr\u003e\u003cbr\u003e\n\nThis kind of sensory focus is the key to realism in your home theater, as well. It’s the job of your center channel loudspeaker to anchor action and dialogue to your screen. It must reproduce detailed high frequency information to reinforce imaging, and also blend seamlessly with the other speakers in your surround-sound system to envelope you in a realistic soundstage.\u003cbr\u003e\u003cbr\u003e\n\nMartinLogan presents a new Masterpiece of home theater realism: the Focus ESL C18 Center Channel Loudspeaker, an electrostatic center channel speaker designed for wall-mounted flexibility.\u003cbr\u003e\u003cbr\u003e\n\n\nOn the wall or on the shelf, there has never been a more adaptable electrostatic speaker.\u003cbr\u003e\u003cbr\u003e\n\nThe goal is flexibility and performance, and the Focus ESL C18 achieves both. The sleek, sculpted enclosure is solidly braced, resonance-free and well-balanced. It is designed to be mounted above or below your screen. Heavy-duty wall-mounting bracket hardware is included, and the innovative brackets accommodate multiple mounting angles, so you can aim the Focus ESL C18 directly at your listening position for a perfectly aligned center channel presentation.\u003cbr\u003e\u003cbr\u003e\n\nThe Focus ESL C18 is also at home on a shelf or floor stand. Toggle the convenient “On-Wall\/Off-Wall” acoustic contour switch to instantly optimize performance for any mounting position. This feature automatically modifies response to compensate for wall boundaries that may reinforce or inhibit bass output. The result is room-filling center channel reproduction with lifelike full-range verve.\u003cbr\u003e\u003cbr\u003e\n\nInstallation flexibility and tailored center channel performance: Now you have more options than ever in your Masterpiece home theater system. \u003cbr\u003e\u003cbr\u003e\n\n\nYes, a wall-mountable electrostatic center channel.\u003cbr\u003e\n\nWhat makes the Focus ESL C18 a masterpiece of center channel design and engineering is its surprising ability to be wall-mounted. And while the Focus ESL C18 boasts a depth of just 9.6-inches when mounted flat on a wall, it is packed with technology that delivers the detailed audio you demand from a superior center channel loudspeaker.\u003cbr\u003e\u003cbr\u003e\n\nThe 7.5 x 18-inch Curvilinear Line Source (CLS) electrostatic panel, with its gentle horizontal curve, enhances output and extends the enveloping mid-range dispersion pattern. The design of the exterior grille matches the look of the MicroPerf Stators and bold AirFrame Blade seen on other models in the Masterpiece ESL Series, for a sophisticated and coordinated home theater system aesthetic.\u003cbr\u003e\u003cbr\u003e\n\n\nExclusive Folded Motion Tweeter\u003cbr\u003e\n\nSituated just behind the electrostatic panel, fixed in a uniquely designed housing, sits a MartinLogan exclusive Folded Motion Tweeter. The low-mass diaphragm of the Folded Motion Tweeter minimizes distortion, while its short excursion length expedites lightning fast high frequency response. The 1 x 1.4-inch Folded Motion Tweeter in the Focus ESL C18 center channel speaker has a diaphragm area of 5.25 x 1.75-inches. The combined performance characteristics of the electrostatic panel and the Folded Motion Tweeter ensure precision and hyper-realistic front-stage blending.\u003cbr\u003e\u003cbr\u003e\n\nThis kind of mid- and high-frequency performance can only be supported by a foundation of tremendous low-end. So the Focus ESL C18 also features a passive array of twin 6.5-inch woofers, capable of deep bass reproduction down to 50Hz. Bass output can be tuned for any installation option with the acoustic contour switch.\u003cbr\u003e\u003cbr\u003e\n\n\nPremium WBT Binding Posts\u003cbr\u003e\n\nConnect your electronics safely and securely using 5-Way audiophile WBT Binding Posts. Their pure copper connection plate is highly conductive and free from eddy current effects. These posts are insulated for shock protection, and fully damped against vibrations. They give you plenty of room for large-gauge professional speaker connections.\u003cbr\u003e\u003cbr\u003e\n\n\nPrecision-Built Advanced-Topology Vojtko Crossover\u003cbr\u003e\n\nVojtko Voiced, the advanced crossover in Focus ESL C18 add enhanced mid-range clarity to this artful composition. Carefully hand-built using only the finest polypropylene capacitors and air-core coils, the crossover employs MartinLogan’s proprietary Vojtko topology for vanishingly low distortion and seamless driver\/ESL integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.\u003cbr\u003e\u003cbr\u003e\n\n\nYes, a wall-mountable electrostatic center channel.\u003cbr\u003e\n\nWhat makes the Focus ESL C18 a masterpiece of center channel design and engineering is its surprising ability to be wall-mounted.
