Same as SH2064m but with 90º bend in throat for racetrack PA or other applications that require up-angle mounting The SH2064M is designed by Community to function as a
midrange horn in multi-way component systems or as a stand-alone, high-power announcement / paging horn. Mated with a Community M4 compression driver it will provide
focused, extremely high output sound projection, with predictable performance and exceptional long term durability. The SH2064M is particularly suited for use with the SH864 HF horn in component clusters. The horn lengths provide physical alignment of the MF and HF drivers when the horn mouths are aligned.
Performance data for Community horns is well documented, providing the designer and consultant with highly predictable and consistent coverage patterns for system design.
Each horn is a handcrafted, one-piece, precision waveguide, precision molded in hand-laminated, fiber-reinforced fiberglass. Balsa wood is embedded in the sidewalls for nondiaphragmatic, resonant-free operation. With substantial fiberglass layering and integral throat and driver flange construction, Community horns are built to withstand the
torque loads of the heaviest compression drivers. Their inherent strength and rigidity enhances sonic efficiency by preventing sound energy losses through the horn walls or
from vibration. Community fiberglass horns are inherently weather-proof under all conditions of use. There is a five year warranty. Horn Type: Pattern Control, Mid frequency horn

1. Sensitivity: Free field pink noise measurement at 25 ft / 7.6 m at
15 percent power; extrapolated to 1 meter and an input of 2.83 volts RMS.
0 dB SPL = 20 uPa.
2. Watts: All wattage figures are calculated using the rated nominal
impedance.
3. EQ: Specifications are without equalization, normally required
for optimum performance.
