A perspective of the current Metallica World Magnetic concert tour in the round, as they’ve done for live performances for almost 20 years. The main loudspeaker set consists of 8 equally spaced line arrays, each containing 12 Meyer Sound MILO, and 4 Meyer Sound MICA self-powered line array loudspeakers. The centrally flown array of subwoofers contains four hangs of 10 Meyer Sound 700-HP loudspeakers. The entire system as well as support for the tour is being supplied by Thunder Audio of Taylor, Michigan.
