2-driver, 2-way in-ceiling / in-wall, GRIP™ chassis / mounting bracket
Signature Custom Sound … Our Commitment to Audio Perfection is Written Moves in-wall / in-ceiling sound beyond the ordinary to the truly extraordinary … Signature Custom sets the ultimate standard for what can be expected, achieved and actually delivered by a speaker system installed in a ceiling. Full-Perimeter Bracket Design. Unlike typical mounting ears, brackets cover the full diameter or height and width of the speaker chassis to effectively sandwich and strengthen the area around the mounting hole. Cutting-Edge P-Be™ Pure-Beryllium Domes. Exotic beryllium! The metal of choice for truly ultimate levels of high-frequency performance. A stiffness-to-density ratio superior to metals such as aluminum, titanium and even diamond. Performance is clear, uncolored and completely uncompromised. Cutting-Edge Co-PAL™ Cobalt-Infused Pure-Aluminum Cones. Combine high stiffness-to-mass ratio with superior internal damping for an even greater degree of accuracy. Advanced Nomex® cloth suspensions and butyl rubber surrounds promote superb and extended excursion. Cutting-Edge Mineral-Filled Co-Polymer Polypropylene Bass Cones. Superior stiffness-to-mass. Precision-engineered for higher sensitivity, power handling and ultra-low levels of distortion. Massive optimized ceramic ferrite or neodymium magnet / motor structures with focused-field geometry. High-Strength GRIP™ Glass-Reinforced Injection-Molded Polymer Chassis / Mounting Bracket. Increased strength and design rigidity reduce resonances, vibration and flexing dramatically! * DIN 45 500. Indicates -3 dB in a typical listening room. † With typical program source, provided the amplifier clips ** Depth required is the distance between 1/2˝ drywall, or similar material. Overview
