****** Page 1 ****** H/GHFREQUWCVPRA/VSDUCER Key Features: Pure titanium dome provides extended high frequency response Lightweight aluminum voice coil for maximum efficiency Unique convex-drive phase plug 1-3/8″ screw on connection Available in 8 and 16 ohms General Description: The Electro-Voice DH2T 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 211 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 DH2T provides smooth response from 800-20,000 Hz.
