The NX18SP is a high-performance 18-inch powered subwoofer built for professional sound reinforcement. Designed as the first 18" subwoofer in the NX series, it delivers rich, powerful bass in a compact, road-ready enclosure. With 2400W peak output and a 4" voice coil, the NX18SP provides deep low-end extension for live music, DJs, and large-scale events.
Engineered to pair seamlessly with NX series speakers, we recommend using one NX18SP with a pair of NX8Ps or two NX18SPs with a pair of NX12Ps for maximum sound coverage. The NX18SP can also enhance any full-range system, giving audio engineers and performers flexibility to create a robust, professional PA setup.
Featuring three selectable voicing modes — Punch, Smooth, and Deep — the NX18SP allows you to tailor your low-end response to the venue and music style. Dual combi-jack inputs and dual XLR link outputs make setup fast and easy, while the durable enclosure ensures road-tested reliability for touring or installation applications.
