User manual ELECTRO-VOICE DH2 DATASHEET

[. . . ] 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. [. . . ] 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 2" 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.
