JBL Control 47HC 6.5" 2-Way 150W Coaxial High-Ceiling Loudspeakers (Pair, White)

Product Overview

The JBL Control 47HC is a passive 6.5-inch coaxial high-ceiling loudspeaker, sold as a pair in white, designed for voice amplification and foreground music in tall, reverberant venues from retail stores to restaurants. A multi-tap 60W transformer allows this 70V/100V high-ceiling speaker to run on 70V, 100V, or 8-ohm amplifiers. Using JBL's conical Radiation Boundary Integrator (RBI) technology with an 11-inch waveguide, it delivers a narrow 75-degree coverage pattern and enhanced speech intelligibility from high ceilings. The coaxial 6.5-inch woofer and 1-inch tweeter provide controlled, full-range output.

Product Description

The Control 47HC is purpose-built for installations where ceilings are too high for conventional wide-dispersion speakers. Each unit pairs a 6.5-inch polypropylene woofer with a 1-inch soft-dome tweeter for a frequency response of 70 Hz to 14 kHz and a continuous program power capacity of 150W. The 11-inch waveguide and RBI technology concentrate output into a well-defined 75-degree pattern, improving sound quality and intelligibility in reverberant spaces while reducing spill onto walls and hard surfaces. Its multi-tap 60W transformer supports 70V and 100V distributed lines plus 8-ohm low-impedance operation. Installation hardware includes removable locking input connectors, detachable grilles, cutout templates, paint shields, and a C-ring / tile rail suspension system.

Frequently Asked Questions

When should I choose the 47HC over the 47C/T?
Choose the 47HC for high or reverberant ceilings: its 75-degree pattern concentrates sound on the listeners below, whereas the 47C/T offers wider coverage for standard ceiling heights.

Can it run on a 70V or 100V distributed line?
Yes. Its multi-tap 60W transformer supports both 70V and 100V systems, and it can also be driven at 8 ohms low impedance.

What is included for installation?
Removable locking input connectors, detachable grilles, cutout templates, paint shields, and a C-ring / tile rail suspension system are supplied.

Does the narrow pattern improve intelligibility?
Yes. By focusing energy on the listening plane and reducing reflections off walls and hard surfaces, the controlled 75-degree pattern improves speech intelligibility in tall spaces.
