The Electro-Voice DL15ST is engineered as a high-performance 15-inch low-frequency driver for demanding professional audio applications where power handling, output, and reliability are critical. It features a sophisticated motor system with a large 3-inch voice coil and a high-strength magnetic structure, designed to convert substantial amplifier power into clean, articulate bass with minimal distortion. This driver is specifically optimized for use in vented (bass-reflex) subwoofer enclosures, where its parameters allow it to deliver deep, extended low-frequency response essential for live sound reinforcement, DJ systems, and installed audio in venues like clubs and houses of worship. Its robust mechanical construction ensures it can withstand the high air pressure and rigorous mechanical stress encountered in high-output subwoofer designs.

Durability and thermal management are central to the DL15ST's design, featuring a rigid die-cast aluminum frame, a treated paper cone for optimal performance, and a high-temperature voice coil winding capable of dissipating heat efficiently. These elements allow it to handle its rated continuous power of 400 watts reliably, even during prolonged, high-volume operation. The driver's high sensitivity rating ensures efficient conversion of amplifier power into acoustic output, making it a powerful yet practical choice for system builders. Whether deployed as a direct replacement in an existing cabinet or as the core component in a custom-built subwoofer, it provides a foundation of dependable, high-impact low-frequency energy.

By combining advanced engineering with proven materials, the Electro-Voice DL15ST serves as a versatile and trustworthy component for audio professionals. It enables the construction of subwoofer systems that deliver the powerful, clean bass required for modern music reproduction and live event production, forming the low-end backbone of professional portable and installed sound systems where performance cannot be compromised.
