3-Inch High Frequency Transducer Specification Sheet

Technical Specifications:
The Electro-Voice DH7 high frequency compression driver
is capable of high acoustic output over a wide frequency
range. Precise engineering, along with careful selection of
materials and advanced driver architecture, has resulted in
a driver that is ideally suited for the most demanding
presentation of high quality music and communications
program.
Incorporating Electro-Voice’s exclusive Ring Mode
Decoupling (RMD) through all design phases has produced
drivers with unmatched accuracy while minimizing any
acoustic resonances, or time domain ringing throughout the
driver structure.
Years of dedicated research and experience in the field
have yielded a new high performance solution for use in
both two and three-way systems, as well as demanding
stand alone horn applications
A unique, geometrically optimized 3" titanium diaphragm,
consisting of a one piece dome and suspension structure,
gives these drivers an ideal combination of superb high
frequency response and resistance to fatigue. The DH7
provides smooth response from 1000-20,000 Hz.
