The Turbosound TSP118B-AN-UL is a high-performance, powered 18-inch subwoofer engineered to deliver powerful and articulate low-frequency reinforcement for both portable sound and permanent installation applications. This system integrates a high-excursion 18-inch driver with a dedicated 3000-watt peak class-D amplifier module, creating a self-contained and potent bass solution. The front-loaded enclosure design is optimized for efficiency and output, providing deep, impactful bass extension that forms the foundation for live music, DJ performances, and immersive audio in venues such as clubs, houses of worship, and portable PA setups. Its powered design simplifies system setup by eliminating the need for external amplification and crossover units, offering a streamlined and reliable plug-and-play solution for low-end reinforcement.

At the core of the subwoofer's advanced functionality is the integrated Klark Teknik digital signal processor and ULTRANET networking capability. The onboard DSP provides comprehensive control over the subwoofer's performance, including low-pass and high-pass filters, parametric equalization, phase alignment, and protective limiting. These tools allow for precise tuning to match the subwoofer to the main loudspeakers and adapt its response to the specific acoustics of the venue. The ULTRANET protocol enables the digital transport of audio, control data, and synchronization clock over a single standard CAT5e cable, facilitating easy integration into larger networked audio systems. This allows for remote management from a compatible digital mixer and simplifies the creation of multi-subwoofer arrays with consistent, time-aligned performance.

The enclosure is constructed from durable 18mm birch plywood with a rugged textured coating, built to withstand the demands of touring and installation. It features integrated handles and heavy-duty casters for easy transport, as well as M10 threaded rigging points for flexible deployment options including ground-stacking and flying. The combination of substantial amplifier power, intelligent networked processing, and robust physical construction makes the TSP118B-AN-UL a versatile and professional-grade component. It delivers the deep, controlled bass required for modern sound systems while offering the operational efficiency and integration capabilities of a fully networked audio ecosystem.
