Model PD-5VT is a 40-watt driver with 2" voice coil. The unit is equipped with a ceramic magnet and includes a built-in, varnish-impregnated, tropic-sealed, multi-tap 70.7 volt line-matching transformer, (also adaptable to 25 volt audio system operation) which offers a selection of terminals for matching to the appropriate impedance and power taps. This durable compression driver mounts easily to large format horns that terminate in the standard 1 3/8"-18 male coupling thread. Model PD-5VT is equipped with corrosion-resistant, screwtype, wiring terminals which are protected by a transparent impact-resistant plastic cover. The protective cover also provides strain relief for interconnecting cable. Units are finished in grey, baked epoxy.
