The JBL Control 67HC/T is a high-output, full-range pendant loudspeaker designed to deliver exceptional sound reproduction with a focus on consistent, narrow coverage. Ideal for spaces with open architecture ceilings, such as convention centers, transit centers, exhibit venues, and hotel atrium areas, this speaker offers superior performance in environments where clarity and intelligibility are paramount.

**Key Features and Design:**

The Control 67HC/T incorporates JBL’s innovative Radiation Boundary Integrator® (RBI) technology, which is adapted from the renowned VERTEC™ Series of line array loudspeakers. This technology ensures highly controlled, narrow coverage, making it perfect for high-ceiling venues or rooms with challenging acoustics. The speaker’s design includes an extra-large 295 mm (11.6 in) diameter waveguide paired with low-frequency projection apertures. This combination provides a seamless integration of coverage, resulting in remarkably even pattern control. The two coaxially-mounted drivers work together to deliver consistent, high-fidelity sound throughout the listening area, ensuring that every listener experiences the same high-quality audio.

**Driver and Acoustic Performance:**

The Control 67HC/T features a robust 165 mm (6.5 in) low-frequency driver with a polypropylene-coated cone. This driver is equipped with a 25 mm (1 in) copper voice coil and a vented fiberglass resin coil-former, which together enhance power handling capabilities and long-term reliability. The coaxially-mounted 25 mm (1 in) textile soft-dome high-frequency driver is designed with internal damping for a smooth, extended response. Its aluminum voice coil former and neodymium magnet assembly, combined with ferro-fluid cooling, contribute to exceptional sound quality and durability, allowing the speaker to maintain high-fidelity sound levels over extended periods.

**Installation and Mounting:**

The Control 67HC/T is designed for easy and secure suspension in open-ceiling applications. It includes a single-point mounting system for straightforward installation. To support this, the speaker comes with two complete hanging cable systems: one for the main suspension and one for safety. These systems feature extra-long 4.5 m (15 ft) high-tensile galvanized steel wire ropes. The cables are equipped with spring clips for easy attachment to the loudspeaker and UL-listed cable fasteners for infinitely adjustable suspension height. This setup ensures that the speaker can be securely installed at the desired height and position.

**Transformer and Versatility:**

The Control 67HC/T includes a high-quality 60 Watt multi-tap transformer, which is compatible with 70V/100V distributed loudspeaker lines. Additionally, the speaker can be switched for 8-ohm voice-coil direct operation, providing flexibility in different audio system configurations. This versatility makes the Control 67HC/T suitable for a range of applications and environments.

In summary, the JBL Control 67HC/T stands out for its advanced technology, exceptional sound quality, and ease of installation. Its narrow coverage pattern ensures precise sound delivery in acoustically challenging environments, while its robust design and transformer options offer flexibility and reliability. Whether used in convention centers, transit hubs, or hotel lobbies, this pendant loudspeaker is engineered to meet the demands of professional audio installations with clarity and consistency.
