The consistently raved about QSC K12s are popular with bands, DJs and audio engineers for use both as an FOH speaker and a stage monitor. It has built in DSP (Digital Signal Processing) which performs a range of functions to keep the sound crisp and clear across a wide range of frequencies and volumes - one proprietary function is DEEP (Digital Extension and Excursion Processing) which allows it to produce low frequencies at volumes not usually associated with a speaker enclosure as small as this - some people even report they get a similar response to using a subwoofer. These speakers have built-in amplifiers, simply connect them to power, adjust the volume accordingly and you're ready to go!
