Electro-Voice DH3 User manual

Technical Specifications:
The Electro-Voice DH3/2010A is a high-performance
compression driver optimized for use as the super-
tweeter component in professional sound reinforcement
systems. 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 (RMDtm) through all design phases has
produced drivers with unmatched accuracy while
minimizing any acoustic resonance, or time domain ringing
throughout the driver structure.
Exceptional high-frequency performance is realized
through a design which includes a specially formed
lightweight titanium diaphragm and low-mass voice coil, a
unique convex-drive phase plug and optimum magnetic
motor design, leading to compact but sensible size and
weight.
Electro-Voice’s commitment to precision compression
driver manufacturing and modern design techniques
assure the DH3/2010A user the highest level of audio
and engineering excellence.
General Description:
