Electro-Voice
The Electro-Voice® MH6040AC is a wide-range, 60 degree x 40 degree, mid-bass/high frequency, Constant Directivity, horn-and-driver system. With a contractor installed high-frequency driver, it covers a 100 Hz to 20,000 Hz range with minimal equalization. The MH6040AC combines two pioneering EV concepts: Constant Directivity horns and Manifold Technology®. The MH6040AC's high acoustical output, stable directional characteristics, and extended, low-frequency performance make it perfect for music and speech reinforcement in large indoor and outdoor venues. At the heart of the MH6040AC are two DL10X-SH 10-inch water-resistant drivers (U.S. patent no. 4,547,632). The drivers have been specially developed for MH Series horns, and feature diaphragms from Kevlar® and epoxy. This combination of materials produces a diaphragm with a strength-to-weight ratio twice that of conventional materials. Each driver is integrally mounted to the fiberglass horn bell via a heavy-duty mounting bracket and proprietary Aperiodic Enhancer phase plug (U.S. patent no. 4,718,517).Manifoldi
ng allows the summing of two or more driver outputs without interference in the band-pass. Manifolding also reduces distortion and increases efficiency at certain frequencies. There is also redundancy built into the system; in the unlikely event of a driver failure, one remains available. The DLX10-SH drivers are contained and sealed within fiberglass covers, and optimally tuned for maximum, low-end performance and displacement control. Frequencies above 1,250 Hz are handled by the EV HP640A Constant Directivity horn and a contractor-selected and installed high-frequency, compression driver.Kevlar® is a registered trademark of DuPont.
