Key Features:
䉴 Extremely consistent 120° broadband
pattern control featuring JBL’s exclusive
conical Radiation Boundary Integrator
®
(RBI™) technology.
䉴 • Very consistent, full-range coverage of
listening area while providing a small
ceiling footprint.
䉴 • Wide, consistent coverage requires
fewer speakers, reducing the cost of the
installed system without sacrificing
performance.
䉴 Coaxial design featuring:
䉴 • 130 mm (5.25 in) polypropylene-coated
paper cone with butyl rubber surround.
䉴 • 20 mm (.75 in) soft-dome tweeter on
210 mm (8.25 in) diameter wave guide.
䉴 Bass extension down 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 45C/T is a premium in-
ceiling professional loudspeaker designed
for applications that can benefit from
extremely wide bandwidth and very
consistent coverage with a small footprint.
Featuring JBL’s exclusive conical
Radiation Boundary Integrator
®
(RBI™),
the tweeter sound is controlled by a large
waveguide while low-frequency sound
projects through specially designed
apertures in the RBI. This design allows
for a seamless integration of coverage
over a wide bandwidth from coaxially-
mounted drivers. The result is that the
sound character is extremely consistent
throughout the listening space with little
variation from location to location. In
addition to providing better coverage of
the listening area, the constant directivity
character of the coverage allows for the
use of fewer loudspeakers compared to
speakers that have less consistent
coverage control.
The large backcan on the Control
45C/T, along with the LF driver design,
provides extended bass response for a
warm full-bodied tone. The system’s
130 mm (5.25 in) woofer features a
polypropylene cone and pure butyl-
rubber surround for long life. The
coaxially mounted 20 mm (0.75 in) soft
dome features ferrofluid cooling for
enhanced power handling and reduced
power compression.
Ideal for small and large projects alike,
the Control 45C/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 Continuous Pink Noise Rating.
