The LE Series medium format constant directivity horns utilize precise geometric formulation to control acoustic coverage patterns across demanding environments like auditoriums, theaters, houses of worship, and stadiums. By managing the horizontal and vertical side-wall contours independently, these horns create an equiphase surface across the horn mouth. This technology ensures uniform frequency response and dispersion while minimizing acoustic distortion and unwanted resonance.

To achieve targeted acoustic performance, proper field integration is required.
Rigging & Mounting: Horns feature structural integration points to accommodate custom array frames or standard yoke brackets.
Driver Integration: Designed for seamless bolt-on mating with high-frequency compression drivers featuring a standard 2-inch exit diameter. Tighten the flange array sequentially to distribute pressure evenly across the polyurethane throat block.
Aiming Alignment: Use geometric or laser-guided positioning based on room acoustic mapping. The LE-M42 provides narrow, long-throw targeting, while the L-M124 provides wide, short-throw lateral coverage.
Crossover Management: Implement a high-pass crossover limit at a minimum of 500 Hz (using steep 24 dB/octave Linkwitz-Riley filters) to prevent low-frequency over-excursion of the attached driver diaphragm.
Equalization (CD Horn Compensation): Constant directivity horns naturally experience a high-frequency roll-off of approximately 6 dB per octave above a specific break frequency. A dedicated digital signal processor (DSP) must apply an inverse high-frequency shelving boost curve to linearize acoustic output up to 16 kHz.
