About the Nexo Alpha E B1-15 Bass Module Passive Loudspeaker

The Nexo Alpha E B1-15 is a high-output, compact bass module designed as part of the renowned Nexo Alpha touring loudspeaker system. This passive subwoofer is engineered to deliver powerful, articulate low-frequency reinforcement for medium to large-scale sound reinforcement applications, including touring concerts, festivals, and fixed installations. It features a rugged, trapezoidal wooden enclosure housing a single long-excursion 15-inch neodymium driver, optimized for efficiency and maximum output. The B1-15 is designed to be used in conjunction with Nexo Alpha full-range cabinets and the proprietary Nexo NXAMPMKII or NXAMP4x1 powered controllers, which provide precise system tuning, driver protection, and optimal power delivery through Nexo's patented Electronic Predictive Protection (EPP) technology.

The cabinet's design incorporates advanced reflex porting to extend low-frequency response and maximize acoustic output. Its trapezoidal shape allows for versatile arraying options, either flown vertically as part of a larger Alpha array or ground-stacked for front-of-house subwoofer deployment. The enclosure is built from durable Baltic birch plywood and finished with a textured, black epoxy coating to withstand the rigors of touring. Integrated handles and multiple rigging points facilitate safe and efficient transportation and deployment. The B1-15 delivers a tight, punchy, and well-defined low-end that complements the Alpha mid-high cabinets, forming a cohesive, scalable system known for its clarity and impact.

As a cornerstone of a professional touring system, the Alpha E B1-15 provides the foundational low-frequency energy required for modern music. Its performance is not merely about raw output but about controlled, musical bass reproduction that remains articulate at high sound pressure levels. When powered and processed by the dedicated Nexo amplifiers, the subwoofer operates as an integral component of a fully optimized system, ensuring reliability, sonic consistency, and the powerful low-end extension that defines the Alpha series' reputation in the professional audio industry.
