Applications:

The Control 45C/T is a premium inceiling 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 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 coaxiallymounted 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 butylrubber 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.

Half-space (in ceiling) average 1 kHz to 16 kHz.

JBL continually engages in research related to product improvement. Changes introduced into existing products without notice are an expression of that philosophy.
