The FH15 is a 2-way, high sensitivity, coaxial horn loudspeaker that provides a precise coverage pattern with control to below 400 Hz, low frequency extension to 54 Hz, and extremely high output using a single amplifier channel. Its 3.5 inch voice coil, 15 inch woofer combines interactively with a 4 inch diaphragm high frequency compression driver to produce precise pattern control through the crossover range. The FH15’s 35° 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 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 FH15 is particularly effective in acoustically challenging spaces where broadband pattern control is necessary, and in applications requiring high acoustic output and high fidelity. 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.
