The Turbosound NUQ118B-AN-UL is a high-performance powered subwoofer engineered to deliver exceptional low-frequency output and control for demanding professional audio applications. Utilizing an efficient band-pass enclosure design, this model houses an 18-inch driver within a dual-chamber architecture that amplifies acoustic output within a targeted frequency range, resulting in powerful, articulate bass with enhanced efficiency. It is powered by a substantial 3000-watt peak Class-D amplifier that is digitally optimized to provide immense headroom and dynamic impact, making it suitable for reinforcing live music, large-scale installations, and touring systems where deep, controlled low-end is critical. The integration of this robust power section with the specialized band-pass acoustics creates a subwoofer capable of high sound pressure levels with pronounced impact.

A cornerstone of this subwoofer's functionality is its advanced onboard Klark Teknik digital signal processing (DSP). This integrated system provides comprehensive control over the audio signal, including precision crossover filters, parametric EQ, dynamic limiting, and time alignment, all accessible and configurable via network software. Furthermore, the unit is fully equipped with the ULTRANET networking protocol, allowing it to function as a node on a fully digital audio network. This enables the subwoofer to receive pristine digital audio, control data, and remote monitoring signals over a single standard Ethernet cable from a compatible digital mixer, dramatically reducing system complexity, cable weight, and potential signal degradation in large-scale setups.

The enclosure is constructed from durable, multi-ply birch and finished in a rugged black textured coating, designed to withstand the physical demands of touring while ensuring long-term reliability. It features integrated handles and multiple M10 rigging points, offering versatile deployment options including ground-stacking, flying in arrays, or integration with full-range NUQ loudspeaker systems. The combination of high-power amplification, efficient band-pass acoustics, sophisticated networked DSP, and a road-ready build makes the NUQ118B-AN-UL a formidable and intelligent foundation for any professional audio system requiring deep, powerful, and meticulously managed low-frequency energy.
