DESCRIPTION

The RMG-200AT is a complete horn/driver system
designed for use in stand-alone voice-range sound
reinforcement and announcement/signaling applications.
The RMG-200AT provides focused, high output sound
projection, with predictable performance and exceptional
long-term durability. The horn portion of the assembly is a
handcrafted one-piece waveguide, precision molded in
hand-laminated, fiber-reinforced fiberglass for optimum
performance. With substantial fiberglass layering and
integral throat and driver flange construction, the horn is
built to withstand substantial torque loads. The inherent
strength and rigidity of the fiberglass construction
enhances sonic efficiency by preventing sound energy
loss, as well as providing inherently weatherproof
fabrication.

The compression driver is a high output, high sensitivity
loudspeaker that is configured with the diaphragm facing
forward, isolating the voice coil and magnetic structure
from the environment. The one-piece, non-metallic
diaphragm/suspension offers exceptional resistance to the
effects of humidity, dust, and corrosive atmospheres. The
large area, low compression phase plug loading and large
magnet structure exhibits extremely low distortion at high
outputs while maintaining high efficiency and low power
compression. A fiberglass rear cover protects the driver
and transformer from the effects of weather and corrosion.

A factory-installed weather-resistant steel swivel yoke
bracket is included. There is a five-year warranty against
manufacturing defects on all components of the system.

ARCHITECTURAL SPECIFICATIONS

The driver shall be a 2-inch (51 mm) exit compression type, specifically designed for midrange frequency response. The 2-inch (51 mm) driver shall be
mounted within a fiberglass exponential horn with an integral fiberglass weather resistant cover incorporating gland nut cable ingress. The horn and
driver combination shall have an amplitude response of 500 Hz to 4 kHz dB (+/- 3.0 dB), with an input capability of 24V RMS, 115 dB sensitivity at 1
meter / 3.4v, and a nominal impedance of 11 Ohms when the coupling autoformer is bypassed. The s ystem shall incorporate a high quality 75W
70V/100V autoformer with multiple power taps. The driver shall incorporate a large magnet structure, a one-piece, non-metallic diaphragm /
suspension, and a copper-clad aluminum edgewound voice coil on a Kapton former immersed in Ferrofluid. The compression ratio shall be 1.84 to 1.
The diaphragm assembly shall be field replaceable. The horn/driver system shall weigh 24.3 lbs (11 kg) with the bracket.
