The LS212 is designed to seamlessly interface with our DML500 and DML500A distributed mode loudspeakers
This high output subwoofer delivers impressive, tight low frequencies that blend perfectly with our DML speakers, making it ideal for churches, clubs, performance venues, and other AV applications.
The secret is an asymmetrical chamber that focuses and synchronizes the two 12-inch direct radiating transducers. It enables the LS212 to produce high sound pressure levels with tight dynamics and musical reproduction of very low frequencies.
Two 12-inch woofers sport massive vented magnets and 3” epoxy-baked copper voice coils. Power handling is a robust 2400W peak and 800W continuous.
With it’s focused bass, the LS212 is an impressive complement to our 85Hz – 24kHz offerings.
