Description:
Control 12C/T is a full-range ceiling speaker consisting of a 76 mm (3
inch) wide-bandwidth cone driver mounted in a vented, paintable baffle
made of UV resistant UL94-V0 material, with a pre-attached blindmount backcan for quick and easy installation. The speaker is designed
to provide excellent sound quality for a wide variety of low to medium
volume applications such as music cafes, business music systems,
retail stores, music/paging systems, airports, reception/waiting rooms,
lounges, courtrooms, convention centers, hotels,
educational facilities,
and more.
The 130° coverage is especially wide, delivering consistent sound quality
for listeners located both off and on axis.
The high-technology cone driver is designed with a lightweight hightemperature Kapton™ voice coil former and aluminum coupling ring to
reduce distortion and extend the high frequency response of the system.
The FEA-optimized motor construction and cone geometry allow for
smooth frequency response and improved off-axis performance. A high-

temperature-grade voice coil
ensures stable performance under longterm/high-power working conditions. The butyl rubber surround provides
long-term durability and good sonic damping, and the polypropylene
cone is water and humidity resistant.
The removable locking connector has screw terminals for secure wire
termination and “loop through” terminals. A dual strain relief assembly
provides clamping for use with cable or flex conduit.
The compact backcan extends only 138 mm (5.4 inches) behind the
baffle, allowing the speaker to fit into more shallow ceiling areas.
Ideal for a wide variety of projects, the Control 12C/T is switchable for
use as either an 8 ohm low-impedance speaker or as part of a 70V or
100V distributed loudspeaker system with a 15W multi-tap transformer.
The speaker comes complete with two tile rail supports, one C-ring
support backing plate, cutout template, paint shield, and grille. A safety
seismic attachment ring is provided on the top surface. Available in white
or black (-BK).

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.
