AtlasIED PD75T 75W 70V Compression Driver for Large Format Horn Speakers

High Efficiency 75 Watt Compression Driver

Model PD75T is a fully environment-resistant 75 Watt driver for indoor or outdoor applications and is recommended for use in expansive and/or high ambient sound-level areas. This model features a sound chamber, phasing plug, magnetic-structure components machined to optimum tolerances, 2" voice coil and offers a plane wave frequency response of 100Hz - 3.7kHz (+5dB).

This unit, which is comprised of a transformer with 16Ω bypass, will meet a variety of applications. The PD75T provides screw-type terminals for matching direct to the 16Ω voice coil impedance and a built-in varnish impregnated, multi-tap 70.7 volt line-matching transformer. Corrosion-resistant terminal connections are protected by a transparent, impact-resistant plastic cover.

The PD75T is terminated in a standard 1 3/8"-18 thread male couplings for use with screw-on horns, or with Atlas Sound Model YDA-TH adapters for bolt-on large format horns. Diaphragms are replaceable with appropriate equipment. A replacement diaphragm, model PD75TDIA, is available.

Internal components are enclosed within a protective die-cast and polycarbonate injection molded housing and finished in gray baked epoxy.
