Mackie SRM450v3 1000 Watts High-Definition Portable Powered Loudspeaker

The first and only portable active 2-way loudspeaker with on-board bi-amplification, active crossovers, time-correction and renowned Mackie sound quality. Thanks to countless hours of R&D and one very-hard-to-please Greg Mackie-the delivers real, accurate bass down to 55 Hz, midrange that's free from ear-fatiguing harshness, and detailed treble out to 20 kHz. Better still, it offers astonishingly wide dispersion that lets your whole audience hear clearly, whether they are in the front, back, or way out on the sides of the room.
