Electro-Voice DH2A w/ Horn

The Electro-Voice DH2A is a high-performance, high-frequency driver capable of unprecedently high acoustic power output over a wide frequency range.

The performance results from careful engineering and design, involving expert choices of materials and advanced driver architecture which are ideally suited for efficient presentation of high-quality musical and communication program materials. Features of the DH2A include:

  1. A unique, geometrically optimized diaphragm consisting of a one-piece ribbed dome and suspension fabricated from pure titanium. Advanced metal forming and processing technology developed by EV engineers allow this high-elongation diaphragm designed to be formed from stock a mere 0.0012-inch thick. The combination of diaphragm geometry and material choice gives the DH2A diaphragm an ideal combination of superb high-frequency response and resistance to fatigue from stress.

  2. A precision, lightweight voice coil made from pure aluminum wire, which gives the DH2A high magnetic motor strength and maximum efficiency. Proprietary high-temperature winding and electrical bonding technologies assure excellent coil reliability and performance.

  3. A new, convex-drive phase-plug design giving optimum upper-octave response.

  4. Screw-type input terminals which are an EV exclusive. They provide an unusually positive electrical connection. Each terminal will accept a pair of 12-gauge wires, and any smaller size. These special terminals were designed using the results of an extensive field survey of consultants and sound-system installers.

  5. The DH2A is unusual in appearance and concept. It would normally be shorter in length and have a smaller throat diameter; a “one-inch driver.” Standard practice would be to provide an “adapter” for this driver for mating it to a 2-inch-throat horn. Extensive surveying of professional users shows a universal dislike for this type of “acoustic plumbing.” The DH2A’s front housing eliminates these problems and provides a direct attachment to a 2-inch horn. This design provides the following features and benefits:

    • A proper flare, assuring a correct low-frequency acoustic impedance match to the horn.

    • Simple, strong horn mounting, saving costly installation time, and eliminating complex and unattractive hardware.
