SPECSHEET
Key Features:
• Components:
• 100 mm (4.0 in) high output driver with polypropylene cone and butyl rubber surround
• 19 mm (0.75 in) liquid cooled soft-dome tweeter
• Blind-mount backcan for quick and easy install
• Dual conduit/cable clamps
• Combined 70V/100V and low impedance direct operation:
• 30
W at 8Ω nominal setting
• 25W multi-tap at 70V/100V
• 74 Hz – 20 kHz bandwidth with wide 120° coverage
• White or black (-BK)
Included grille not shown
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 and 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 25W
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).
Description:
Control 14C/T is a full-range ceiling speaker consisting of a 100 mm
(4 inch) high-tech cone driver and a 19 mm liquid cooled soft-dome
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) low-frequency 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 long-term durability and excellent sonic
damping while the polypropylene cone is water and humidity resistant.
