The Turbosound NUQ115B is a powered 15-inch front-loaded subwoofer engineered to deliver deep, impactful low-frequency extension for portable sound reinforcement and permanent installation systems. It is designed to complement the NUQ series full-range loudspeakers, forming a cohesive and powerful PA solution for live music, DJ performances, and corporate events. The enclosure houses a high-power 15-inch long-excursion woofer with a robust motor structure, optimized to move large volumes of air efficiently and produce substantial sound pressure levels with low distortion. Its front-loaded, bass-reflex design, tuned via a precision-ported baffle, extends the low-frequency response while maintaining control and punch, ensuring the subwoofer provides the foundational energy required for modern music genres.

The system is driven by a potent integrated Class-D amplifier paired with comprehensive DSP (Digital Signal Processing) from Klark Teknik. This amplifier provides substantial dedicated power to the woofer, while the onboard DSP manages critical functions such as precise crossover filtering, phase alignment, driver protection limiters, and system EQ. The inclusion of ULTRANET digital audio networking allows the NUQ115B to be seamlessly integrated into larger Turbosound systems; it can be daisy-chained with other ULTRANET-equipped speakers and subwoofers using a single Cat-5e cable, transmitting audio, control data, and phantom power. This simplifies setup, reduces cable runs, and enables centralized control of the entire low-end array from a mixing console or software.

Built into a rugged, tour-grade plywood cabinet with a durable textured finish, the subwoofer features integrated handles and heavy-duty rigging points for easy transport and versatile deployment. Its cabinet design is optimized for both standalone use and stacking with top boxes. For system integrators and mobile DJs, the Turbosound NUQ115B offers a powerful, self-contained low-frequency solution that combines high-output performance with modern connectivity and intelligent processing, making it a reliable and flexible cornerstone for building full-range sound systems that deliver clarity and power across the entire frequency spectrum.
