The Electro Voice DH1A-WP is a weather proof version of the DH1A high-frequency compression driver. The driver is capable of unprecedentedly high acoustic power output over an extremely wide frequency range.

The DH1A-WP is intended primarily for outdoor use with the HP series horns. Typical applications would include large outdoor systems such as ball parks, race tracks, and stadiums.

  • 6 ohms Compression Driver for PA System / Loudsystem / DJ Horn Speaker
  • Power frequency response: 500-20000 Hz (essentially flat 500-5000 Hz with 6 dB/octave rolloff to 20000 Hz, rapid rolloff beyond)
  • Nominal impedance: 8 ohms
  • Minimum impedance, on HP Series Horns above 500 Hz: 7 ohms at 6000 Hz
  • DC resistance: 4.5 ohms
  • Long-term average power capacity on HP horns, indicated bands of pink noise, 8-ohms impedance assumed:
    • 24 hours, 6 dB crest factor: 50 watts (500-20000 Hz)
    • 2 hours, 6 dB crest factor: 75 watts (1000-10000 Hz)
  • Nominal efficiency, 1000-5000 Hz pink noise, 8 ohm impedance assumed: 25%
  • Maximum long-term acoustic power output (24 hours): 10 watts
  • Recommend minimum crossover frequency: 500 Hz
  • Sound pressure level at 1 meter, 1 watt input averaged from 500 Hz to 5000 Hz:
    • 115 dB, HP4020 horn
    • 113 dB, HP6040 horn
    • 111 dB, HP9040 horn

  • Voice coil construction: Rectangular edge-wound pure aluminum wire on a high-temperature polyimide form
  • Diaphragm construction: Integral all-titanium construction consisting of spherical diaphragm dome and geometrically optimized suspension; a low fatigue, high temperature, long duration cure engineering polymer bonds the coil form to the diaphragm
  • Electrical connection: Screw terminals, each of which will accept a pair 12-gauge wires and any smaller
  • Polarity: A positive voltage applied to the positive (+) terminal produces a positive acoustic pressure in the throat
  • Mechanical connection: Bolt on, 4 equally spaced holes on a 4" diameter circle, 1/4" - 10 threads, bolts supplied with HP series horns
  • Dimensions: 8.88" Diameter x 8.88"H
