db Sound recently provided an Electro-Voice X-Line line array loudspeaker system for radio station Q101’s eighth annual alternative music festival at Chicago’s United Center. A sell-out crowd of 18,000 turned out to see Blink 182, Bush, Puddle of Mudd, Alien Ant Farm, Sum 41, Pete Yorn and Crystal Method. The main P.A. system consisted of two front speaker hangs of 16 E-V X-Line Xvls, six Xvlt, and two Xfil loudspeaker models. Two columns of 11 X-Line Xsub loudspeakers were also flown.
