Description.
The AHC4 is a tri-amplified 2-way, high sensitivity, arrayable coaxial horn loudspeaker that provides a precise coverage pattern with control to below 400 Hz, low frequency extension to 70 Hz, and extremely high output with modest amplifier power. Its unique Compression Head™ horn architecture provides exceptional low frequency loading to its four 10 inch low frequency compression drivers, while four Oculus™ phase plugs extend the 10s’ high frequency response to smoothly mesh with two coaxial ring-radiator high frequency compression drivers. The AHC4’s unique 30° compact trapezoidal shape allows it to be deployed with its trapezoidal profile vertically oriented for stand-alone use, in distributed systems, or in vertical arrays; or with its trapezoidal profile horizontally oriented for use in horizontal tight-packed arrays.
Sound, innovative acoustical design combined with Fulcrum Acoustic’s TQ™ processing leads to exceptional clarity and precise transient response, even at very high sound pressure levels. The required digital signal processing can be provided by one of many supported platforms.
The AHC4 is particularly effective in acoustically challenging spaces where broadband pattern control is necessary, and in applications requiring high acoustic output and high fidelity. Its Compression Head™ horn architecture provides easy access to the drivers, so the AHC4 can be conveniently serviced while flown. Its clean aesthetic and relatively compact size complements many architectural styles, which facilitates acceptance by interior designers and architects. This makes it the perfect choice for houses of worship, sports facilities, theatres, night clubs, theme parks, and more.
