LS118

High output single 18-inch bass reflex subwoofer

Specifically designed to accompany and complement our DML500 and DML500A loudspeakers.

  • High output subwoofer system, bass reflex, semi horn-loaded port design
  • Can be used in single, dual, and quad configurations
  • Scales into dual and quad systems

Details that make it professional

  • Professional 16-ply birch construction with wear-resistant polymer coating
  • Four recessed handles for simplified handling and carrying
  • Acetyl copolymer, high impact, low friction feet are located on the bottom to allow lock-in and easy cabinet movement

Where our DML500 loudspeaker leaves off, the LS118 takes over

Remarkably compact, this high output subwoofer delivers impressive, tight low frequencies that blend perfectively with our full-range speakers.

With an 18” direct radiating transducer, the LS118 produces high sound pressure levels with fast dynamics and musical reproduction of very low frequencies.

Its 18-inch woofer is armed with massive vented magnets and 4” copper voice coil. Power handling is an impressive 3500W peak and 1200W continuous.

The LS118 is an impressive complement to our DML500 and DML500A loudspeakers

As a companion to our DML500 and DML500 loudspeakers, or as a tight, focused bass source for portal PA systems, the LS118 will impress your audience.
