JAM Systems S118 Single Subwoofer Cabinet for 1 x 18" Driver - Assembled and Painted

Built for powerful, efficient bass reproduction, the JAM Systems S118 is a professional 18" bass-reflex subwoofer cabinet designed for live music, mobile DJs and general-purpose sound reinforcement. Constructed from CNC-cut 18mm birch plywood and finished in a tough PolyUrea coating, it is built to withstand the demands of regular transport, installation and hire use. Tuned to approximately 38Hz, the S118 delivers an excellent balance of efficiency, punch and low-frequency extension, making it an ideal partner for a wide range of professional 18" subwoofer drivers.

Measuring 512mm high × 580mm wide × 753mm deep, the cabinet combines a relatively compact footprint with an internal volume of approximately 155 litres. Integrated CNC-cut wooden handles provide exceptional strength while eliminating the need for metal handle assemblies, a design approach commonly found in professional touring loudspeaker systems.

This cabinet is supplied fully assembled and finished in a durable Polyurea coating, ready for installation of your chosen driver and hardware. The front baffle is pre-drilled with grille mounting points, allowing a matching steel grille to be fitted if required. Cabinets supplied prior to 2026 were finished in TuffCab speaker paint rather than Polyurea
