Biamp Community RSH-462 Exponential FocusedArray™ High Level Horn System

The RSH-462 is a complete horn/driver system designed for use in standalone voice-range sound reinforcement and announcement/signaling applications. The RSH-462 provides focused, very high output sound projection, with predictable performance and exceptional long-term durability. The horn portion of the assembly is a handcrafted one-piece Patented FocusedArray wave-guide, precision molded in hand laminated, reinforced fiberglass for optimum performance. With substantial fiberglass layering and integral throat and driver flange construction, the horn is built to withstand substantial loads. The inherent strength and rigidity of fiberglass construction enhances sonic efficiency by preventing sound energy loss as well as providing an inherently weather resistant installed loudspeaker system.

The compression drivers are high output, high sensitivity loudspeakers that are configured with the diaphragm facing forward, isolating the voice coil and magnetic structure of each driver 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 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 drivers from the effects of weather and corrosion. A weather-resistant mounting bracket assembly is included with the loudspeaker system.
