Key Features:
䉴 Focused 75° narrow pattern featuring
JBL’s exclusive conical Radiation
Boundary Integrator
®
(RBI™) technology.
• Provides consistent coverage within the
listening area.
䉴 • Narrow coverage makes the system
ideal for high-ceiling applications,
minimizing time arrival anomalies and
improving speech intelligibility.
䉴 Coaxial design featuring:
• 165 mm (6.5 in) woofer with butyl
rubber surround.
䉴 • 25 mm (1 in) soft-dome tweeter on
280 mm (11 in) diameter wave guide.
䉴 8 ohm and 70V/100V operation.
䉴 Integrated backcan for easy “blind-mount”
install. Packaged with grille and tile rails
for easy installation.
Applications:
The Control 47HC is a premium in-ceiling
professional loudspeaker designed for
applications that require a focused
beamwidth pattern along with very
consistent coverage.
Featuring JBL’s conical Radiation
Boundary Integrator
®
(RBI™), the RBI
provides a large waveguide for the tweeter
while low-frequency sound projects through
specially-designed apertures in the RBI,
allowing for a seamless integration of
coverage between the two coaxially-
mounted drivers. The result is extremely
consistent sound character with very little
variation throughout the listening space. The
Control 47HC’s narrow coverage pattern
makes the system ideal for high ceiling
applications where the focused pattern
helps minimized time arrival anomalies from
adjacent loudspeakers, resulting in improved
speech intelligibility.
The large backcan on the Control 47HC
along with the LF driver design, provides
extended bass response for a warm full-
bodied tone. The system’s 165 mm (6.5 in)
woofer features a polypropylene cone and
pure butyl-rubber surround for long life.
The copper-clad aluminum voice coil
wound on a vented aluminum former
provides low distortion and high sensitivity.
The coaxially mounted 25 mm (1 in) soft
dome features internal damping for smooth
extended response and ferrofluid cooling
for enhanced power handling and reduced
power compression. The result is crisp,
clear highs.
Ideal for small and large projects alike,
the Control 47HC is switchable for use as
either an 8-ohm low-impedance speaker, or
as part of a 70V/100V distributed
loudspeaker system.

Continuous Pink Noise rating is IEC-shaped pink noise with a 6 dB crest factor for 100 hours continuously. Continuous
Program power is a conservative expression of the system’s ability to handle normal speech and music program
material, and is defined as 3 dB above the Continous Pink Noise Rating.
