General Description:

The Electro-Voice EVH-1152D/66 is a high-power, two-way horn-loaded coaxial loudspeaker system that can be used in a variety of applica- tions where excellent sound reinforcement, wide bandwidth directivity control, and high efficiency is required in a compact package.

The EVH-1152D/66 utilizes the DH7N, a high-output 3” titanium com- pression driver, coupled to a Constant Directivity™ 60° x 60° waveguide. The SMX2151 15” woofer was developed using FEA optimization for motor, suspension, and electrical design to ensure very low distortion, high efficiency, and maximum intelligibility at high SPL. The crossover uses steep, 24-dB-per-octave slopes with equalization for very smooth response in the vocal range, linear off-axis response, and a protection circuit for long-term reliability. This combination of technologies results in a smooth response to 20 kHz and excellent pattern control down to 500 Hz.

The EVH-1152D/66’s features make it ideal for many fixed-install appli- cations. The trapezoidal enclosure is constructed of weather-resistant birch, and coated with EVCoatTM for protection from the elements. For maximum protection against extreme outdoor elements, a fully-weath- erized fiberglass version is available. The unique acoustic and rigging design allows for vertical and horizontal clusters to be built using any combination of loudspeakers from the entire EVF and EVH series. With seven horn patterns to choose from, along with an assortment of low- frequency and subwoofer loudspeakers, you have the tools to maxi- mize flexibility of system design, no matter what the application and budget. The innovative input panel provides a choice of Phoenix-style connector (included in all standard models) or the ability to add a dual NL4-type connector cover plate or gland-nut cover plate (for weather- izing applications). An externally accessible jumper selects passive or active operation. An available 70.7/100-V transformer kit may be easily mounted to the input panel for use in distributed systems. All these features give you the flexibility to address a large range of venues, quickly and precisely supporting customer requirements with fewer items in inventory.
