The PD-60A is a fully environment-resistant Sixty watt driver for outdoor or indoor application suitable for use in expansive and/or substantial ambient sound-level locations. The unit features magnetic-structure components produced to ideal tolerances, 2" voice coil and a plane wave frequency response of 100 - 3,700 Hz (+5dB). The PD-60A provides screw-type terminals for matching direct to the 16 ohm voice coil impedance. Corrosion-resistant terminal connections are protected by a clear, impact-resistant plastic cover that provides strain relief for the interconnecting cable. The PD-60A is terminated in standard 1 3/8"-18" thread male couplings to be used with screw-on horns.
