Passive 18-Inch Array Subwoofer LA-118S
The LA-118S is a professional single-driver array subwoofer engineered to extend line array systems with powerful, controlled low-frequency reproduction. Its 18-inch ferrite woofer, 100 mm copper voice coil, high-sensitivity acoustic design, and integrated rigging hardware allow the subwoofer to deliver deep bass for concert venues, auditoriums, clubs, touring systems, and large fixed sound installations.
Product Description
- Powerful 18-inch low-frequency driver: The ferrite woofer and 100 mm voice coil deliver strong bass impact, high output capability, and controlled transient response.
- Low-distortion acoustic performance: Integrated feedback control circuitry improves transient accuracy while reducing distortion at demanding output levels.
- Flexible array configuration: The LA-118S can be flown or ground-stacked in cardioid and omnidirectional configurations according to venue and coverage requirements.
- Professional power handling: Supports 900 W RMS and 1600 W peak power for live sound, touring, and permanent installation applications.
- Extended bass reproduction: A frequency response of 30 Hz–300 Hz provides the low-frequency depth required for music and large-format sound reinforcement.
- Integrated flying hardware: The built-in suspension bracket simplifies mechanical integration with compatible professional array systems.
- Heavy-duty protective grille: A powder-coated steel grille protects the driver against impact while maintaining a clean and robust appearance.
- Premium plywood enclosure: CNC-machined high-density birch plywood with scratch- and moisture-resistant coating supports reliable long-term use.
- Practical system handling: Four integrated handles provide convenient positioning, transportation, and system setup.
- Reliable loudspeaker connectivity: Dual NL4 Speakon®-compatible connectors support secure signal connection and system linking.
