JBL Control 47C/T 6.5" 2-Way 150W Coaxial Ceiling Loudspeakers (Pair, White)

Product Overview

The JBL Control 47C/T is a passive 6.5-inch coaxial ceiling loudspeaker, sold as a pair in white, designed for voice amplification and foreground music in commercial venues from boardrooms to bistros. A multi-tap 60W transformer allows this 70V/100V ceiling speaker to run on 70V, 100V, or 8-ohm amplifiers for flexible distributed-audio installs. A large backcan extends bass response to 55 Hz, while JBL's conical Radiation Boundary Integrator (RBI) technology provides wide, consistent coverage. The coaxial 6.5-inch woofer and 1-inch tweeter deliver flat, full-range sound for commercial ceilings.

Product Description

The Control 47C/T balances intelligible speech with full-range foreground music for distributed ceiling systems. Each speaker pairs a 6.5-inch polypropylene woofer with a 1-inch soft-dome tweeter for a frequency response of 75 Hz to 17 kHz and a continuous program power capacity of 150W. Its multi-tap 60W transformer supports 70V and 100V distributed lines plus 8-ohm low-impedance operation. JBL's conical RBI technology delivers wide, consistent broadband coverage, and a large backcan extends bass response down to 55 Hz for fuller sound than typical ceiling speakers. The speaker installs quickly with removable locking input connectors, detachable grilles, cutout templates, paint shields, and a C-ring / tile rail suspension system.

Frequently Asked Questions

Can the Control 47C/T run on a 70V or 100V distributed line?
Yes. Its multi-tap 60W transformer supports both 70V and 100V distributed systems, and it can also be driven at 8 ohms low impedance.

How does it differ from the Control 47LP and 47HC?
The 47C/T is the standard wide-coverage model with a large backcan for bass to 55 Hz. The 47LP is a shallow-backcan low-profile version, and the 47HC is a narrow-coverage model for high ceilings.

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.

How many speakers do I need for a given area?
Because RBI technology provides wide, consistent coverage, fewer speakers are typically required than with conventional ceiling speakers; a contractor should model coverage against ceiling height and listening plane.

What warranty and support apply?
The Control 47C/T carries JBL Professional's manufacturer warranty. For system design and integration support, contact our team or browse the JBL Professional installed audio collection.
