Description
QSC LS118 – Powerful 18-inch subwoofer for L Class
The QSC LS118 is a professional active 18-inch subwoofer, specifically developed as part of the QSC L Class line array system. This powerful subwoofer combines deep, controlled low-frequency reproduction with high sound pressure levels and extensive system integration.
The LS118 features a specially developed 18-inch long-excursion driver and a powerful 4000 Watt Class D amplifier module. With a maximum sound pressure level of no less than 138 dB peak, this subwoofer is excellent for professional events, concerts, festivals, live music, DJ productions, and mobile PA systems.
A major advantage of the LS118 is its extensive digital integration. The system can be configured, controlled, and monitored via QSC SysNav. Additionally, the LS118 supports Dante for digital audio and network control within professional installations and productions.
The LS118 can be used in both omnidirectional and cardioid modes. A cardioid setup can be created with at least two units, significantly reducing unwanted low frequencies at the rear of the stage. The built-in DEEP mode also provides extra low-frequency extension when desired.
The robust birch plywood enclosure with Polyurea coating and four sturdy, quiet casters make the LS118 suitable for intensive professional use. Combined with the QSC LA108 or LA112, it creates a powerful and scalable L Class PA solution.
