The key to achieving the amazing sound you desire from such a compact loudspeaker is simple. You need tons of pure, raw power. Each DLM model features a staggering 2000 watts of power.

The powerful Class-D amplifiers are ultra-efficient with optimum heat dispersion and ample protection circuitry to keep things running smoothly night after night. DLM delivers maximum power in a minimal space with plenty of headroom to crank it up.

One of the most significant technological innovations of the DLM line is Mackie TruSource™ Technology. It's a potent combination of a brand new, completely unique, transducer design and powerful proprietary digital signal processing. Both full-range models feature the extremely compact TruSource driver, which combines the high and low-frequency driver into a vertically-aligned, common-magnet design that is ultra-efficient and extremely capable. The sonic reproduction is incredibly transparent across the entire frequency range. DLM Series loudspeakers deliver unmatched fidelity.
