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 130mm (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.
