[QUOTE="Art Welter, post: 218668, member: 52"] Roelof, If your QSC KW122 are raised above head level, they are capable of over 90dB SPL at 30 meters. Your four dual 12 subs can get louder than that. That's loud enough for a party atmosphere, and is around the permissible NIOSH SPL limit of 90 dB for 151 minutes. Halfway back in the tent, SPL will be around 6dB louder, at 96dBA (slow) the NIOSH SPL limit drops to 38 minutes. Near the speakers, SPL could be over 110dB, the NIOSH SPL limit drops to just one minute. The World Health Organization noise guidelines for the European Region are similar. Art [/QUOTE]
