JBL continually engages in research related to product improvement. Some materials, production methods and design

refinements are introduced into existing products without notice as a routine expression of that philosophy. For this

reason, any current JBL product may differ in some respect from its published description, but will always equal or

exceed the original design specifications unless otherwise stated.

Applications:

The JBL Professional Control 227C and CT

are premium in-ceiling professional

loudspeakers designed for applications

requiring superior quality sound in ceiling-

mount applications. Delivering exceptional

next-generation performance in a medium

format coaxial point source design, the

Control 227C and CT incorporate

breakthrough performance features such as

best-in-class pattern control to provide a

consistent sound throughout the listening

area. Especially wide coverage allows fewer

speakers to cover the space, reducing both

the material and labor cost for the

installation.

The Control 227C and CT feature a

165 mm (6.5 in) Kevlar-reinforced low

frequency driver coupled with a 25 mm

(1 in) exit titanium compression driver for

enduring reliability and outstanding

performance. An 8 ohm driver is utilized on

the Control 227C and offers 150 Watts of

continuous power handling capability, while

a top quality, low saturation 68 Watt multi-

tap transformer comes pre-attached on the

Control 227CT enabling the system to be

used on 70V or 100V distributed speaker

lines.

The Control 227C and CT are easy to

install and feature a removable multi-pin

locking connector, with secure screw-down

terminals. This allows for pre-wiring the

input wires for easy clip-on convenience

during installation. The optional MTC-

200BB6 14 cubic liter (0.5 cubic foot) back

can is made of extra-thick 16 guage steel

and the top is lined with 1/2" medium

density fibreboard.

The clean, contemporary look of the

MTC-RG6/8 grille for the Control 227C and

CT is designed to suit a variety of settings,

offering a simple, elegant appearance that

fits into a wide variety of décors.

To ensure long life and reliability, Control

227C and CT pass JBL’s 100-hour torture

power test. Nobody in the industry has

more demanding reliability standards.
