Applications:
Control 14C/T is a full-range ceiling speaker
consisting of a 100 mm (4 inch) high tech cone
driver and a 19 mm soft-dome liquid cooled
tweeter mounted in a vented, paintable baffle
made of UV resistant UL94-V0 and UL94-5HB
material, with a pre-attached blind-mount
backcan for quick and easy installation. The
speaker is designed to provide excellent sound
quality for a wide variety of 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 120° coverage delivers consistent sound
quality for listeners located both off and on axis.
The high technology 100 mm (4.0 in) lowfrequency driver is designed with a lightweight,
high temperature anodized aluminum voice
coil former and high temperature grade voice
coil for stable performance and reliability under
long-term high power working conditions.
The butyl rubber surround provides longterm durability and excellent sonic damping
while the polypropylene cone is water and
humidity resistant. The FEA-optimized motor
construction and cone geometry, along with
linear suspension spider design, allows for a
smooth frequency response and more consistent
off-axis performance. The 19 mm (3/4 in) high
frequency driver features a highly damped
treated silk dome for clear and warm sound, a
lightweight Kapton™ voice coil for better high
frequency response and excellent reliability, low
viscosity liquid cooling for power handling and
reliability, and a wide dispersion waveguide
design to produce wide coverage and smooth
frequency response.
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.
Ideal for a wide variety of projects, the
Control 14C/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 25 Watt 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.
