2,000-watt Powered PA Speaker with 12" LF Driver, 1.75" HF Driver, Feedback Suppression, Built-in 2-ch Mixer, 16 Effects, and Alignment Delay (each). You can rely on the Mackie DLM12 powered loudspeaker for clear, powerful live sound much more than you'd expect from its small size. That's because the DLM12 boasts 2,000 watts of Class D amplification, powering a custom-designed 12" woofer and 1.75" HF compression driver. It has the power and quality to base your band's PA on, with built-in feedback suppression, six voicing modes, and up to 300ms of delay for alignment in larger speaker arrangements. But its built-in mixer and 16 great-sounding effects make the DLM12 the perfect speaker for solo singer/songwriter performances too.
