The EAW QX118-BK is an 18-inch passive subwoofer engineered for high-impact low-frequency reinforcement in demanding professional audio applications, including live sound, DJ systems, and fixed installations. It is designed to deliver powerful and extended bass with high efficiency, making it suitable for small to medium-sized venues where space and setup time are considerations. The subwoofer features a high-performance 18-inch driver housed in a tuned, ported (bass-reflex) enclosure that maximizes output and extends low-frequency response while maintaining control and reducing distortion. Its black (BK) finish and rugged construction make it a practical choice for both touring and permanent installation, where durability and a discreet appearance are important.

Constructed with a durable, braced plywood cabinet and a textured exterior coating, the QX118-BK is built to withstand the rigors of transport and heavy use. The enclosure includes integrated handles for easy lifting and multiple rigging points for flexible deployment options, including ground-stacking or pole-mounting with compatible full-range speakers. As a passive design, it requires an external power amplifier and system processing, providing sound engineers with the flexibility to tailor the subwoofer's performance to the specific requirements of the venue and the main loudspeaker system. With its combination of solid output, robust construction, and practical features, the EAW QX118-BK provides a reliable foundation for enhancing the low-end impact of a professional sound system.
