JBL CONTROL 47C/T Datasheet
Control
Professional Series
Key Features:
䉴
Extremely consistent 120° broadband
pattern control featuring JBL’s exclusive
conical Radiation Boundary Integrator
(RBI™) technology.
• Provides very consistent coverage of
listening area.
䉴
• Wide coverage requires fewer speakers,
reducing the cost of the installed
system without sacrificing performance.
䉴
Coaxial design featuring:
• 165 mm (6.5 in) woofer with butyl
rubber surround.
䉴
• 25 mm (1 in) soft-dome tweeter on
250 mm (10 in) diameter wave guide.
䉴
Bass extension to 55 Hz.
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 47C/T is a premium inceiling professional loudspeaker designed
for applications that require extremely wide
bandwidth along with very consistent
coverage.
Featuring JBL’s exclusive conical
Radiation Boundary Integrator
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 coaxiallymounted drivers. The result is extremely
consistent sound character with very little
variation throughout the listening space. The
wide coverage allows for the use of fewer
loudspeakers compared to speakers with
less consistent coverage control, while at the
same time providing better coverage of the
area.
The large backcan on the Control 47C/T,
along with the LF driver design, provides
extended bass response for a warm fullbodied 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 47C/T 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.
