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.

Churches
Educational facilities
Gymnasiums
