The Control 67HC/T is a high output, full range, two-way pendant-type loudspeaker that provides superb sound reproduction and very consistent, narrow coverage for rooms with open architecture ceilings and other locations where a pendant form factor is desired. The well-controlled narrow coverage is ideal for improved voice intelligibility and musical clarity in high-ceiling venues or in rooms with difficult acoustics such as convention centers, transit centers, exhibit venues and hotel atrium areas. JBL’s patent-pending Radiation Boundary Integrator® (RBI) technology, adapted from the groundbreaking VERTEC™ Series of line array loudspeakers, delivers consistent coverage of the listening area. Combining an extra-large 295 mm (11.6 in) diameter waveguide with low frequency projection apertures, the two coaxially-mounted drivers provide a seamless integration of coverage, resulting in extremely even pattern control and coverage where all listeners hear a consistent, high-fidelity sound quality. The Control 67HC/T includes a single-point mounting system for easy and secure suspension in open-ceiling applications. Two complete hanging cable systems are included, providing both main and safety suspension cables. Include are extra-long 4.5 m (15 foot) high tensile galvanized steel wire rope having spring clips for the loudspeaker end of the cable and UL listed cable fasteners for infinitely adjustable suspension height. The system’s 165 mm (6 1/2 in) low-frequency driver features a polypropylene-coated cone and 25 mm (1 in) copper voice coil with vented fiberglass resin coil-former for high power handling and improved long-term reliability. The coaxially-mounted 25 mm (1 in) textile soft dome high frequency driver features internal damping for smooth extended response, along with an aluminum voice coil former and neodymium magnet assembly with ferro-fluid cooling, for high-fidelity sound quality with enhanced long-term sound level capability. The Control 67HC/T contains a high-quality 60 Watt multi-tap transformer for use on 70V/100V distributed loudspeaker lines, and is switchable for 8-ohm voice-coil direct operation. Euro-style clip-in connectors allow for easy wiring. For protected outdoor applications, rubber boots are included to cover the input connectors, and an optional terminal cover is available for harsher locations.
