The Electro-Voice XCB is a dedicated 18-inch bass system component designed as part of the professional X-Array series to deliver powerful, extended low-frequency reinforcement for large-scale concert touring and major fixed installations. This subwoofer enclosure houses a high-performance 18-inch driver within a precisely engineered, ported cabinet optimized for maximum efficiency and output in the sub-bass and low-bass frequency ranges. Its design integrates seamlessly with other X-Array elements, allowing it to be flown, ground-stacked, or integrated into large arrays to form a cohesive, high-output low-frequency foundation that supports the main loudspeaker system with authority and control.

Built for the extreme demands of touring, the XCB features a rugged, void-free birch plywood construction with a textured, durable finish that resists damage during transport and handling. The cabinet incorporates robust rigging hardware that aligns with the X-Array interlocking frame system, enabling safe and secure arraying with other XCB cabinets or full-range X-Array components. As a passive design, it requires external, high-current amplification and dedicated system processing, which allows audio engineers to apply precise equalization, crossover points, and limiting to optimize performance for the specific venue and protect the driver from damage during high-power operation.

Sonic performance is characterized by its ability to produce extremely high sound pressure levels with deep extension and punch, providing the visceral low-end impact required for modern live music and large-format sound reinforcement. The cabinet's tuned porting and internal bracing minimize unwanted resonances, contributing to a tight, articulate bass response. For system designers and touring engineers, the XCB represents a critical, reliable building block for constructing scalable low-frequency arrays capable of delivering consistent, powerful bass that can be felt throughout the largest venues, ensuring the audio system's full-range integrity and impact.
