Power headroom.

Equations used to calculate the data:dBW = Lreq - Lsens + 20 * Log (D2/Dref) + HRW = 10 to the power of (dBW / 10) Where: Lreq = required SPL at listener. Lsens = loudspeaker sensitivity (1W/1M) D2 = loudspeaker-to-listener distance. Dref = reference distance. HR = desired amplifier headroom. dBW = ratio of power referenced to 1 watt.

Although a rock concert in an arena could be powered by 15,000 watts (allowing only 6 dB of headroom for peaks,) you'll often see large touring sound companies using 80,000 to 400,000 watts total. That much power is needed to handle 20-to-24 dB peaks without any clipping, and to power extra speakers for even coverage of a large area.
