The DL15X low/mid-frequency reproducer is a 15-inch, 8-ohm driver designed for professional high-level, high-fidelity monitoring and sound reinforcement. At the heart of this speaker is a carefully engineered drive system. Its design assures linear, low-distortion output, high power capability and efficient heat transfer.

Incorporated into the design are three exclusive Electro-Voice innovations. PROTEFTM coating (U.S. patent #4,547,632), a Teflon® -based coating, is applied to the inside diameter of the
top plate.4 Occasional violent power peaks of several seconds may expand a transducer’s voice coil into contact with the top plate, causing failure. PROTEF provides protection against such failure. The coating lubricates any rubbing contact and provides electrical insulation between the coil and the steel top plate. The
Thermo Inductive Ring (TIRTM) and Flux Demodulation Device (FDDTM), also included in the DL15X design, are aluminum castings fastened to the pole of the magnet. They provide a shorted turn to control inductance and provide a major heat transfer path from the voice coil, which improves power handling and reduces thermal dynamic-range compression.

The voice coil itself is constructed of edgewound rectangular aluminum wire, mounted on a rugged, laminated polyimide former. The complete assembly is low in mass and is fabricated
using the most advanced epoxies, insulations and materials available. Great care was taken in the selection of diaphragm
materials and construction to ensure smooth, musical upper-bass reproduction and accurate low-frequency shock capability
(punch). The cone has a moisture-repellent treatment, allowing it to be used in harsh and humid conditions. (Do not expose the cone to direct water or sunlight.)

The DL15X is a true high-fidelity woofer in every sense, being capable of high output, low distortion and solid bass response.
