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 applications 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 compression 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 applications. 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-weatherized 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 lowfrequency and subwoofer loudspeakers, you have the tools to maximize 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 weatherizing 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.
