As many of you know I am a touring musician and I and my band mates own several complete large sound systems. Now on stage we have our own personal amps and speakers such as each guitarist will run 6-200 watt Marshall Heads...amps...each one powering 2 4x12 inch Celestron Speakers...thus each head powers 8 12 inch speakers in 2 cabs.
The bass player uses...depending upon venue...and same with the guitarists...6 Gallien Krueger Bass amps putting out 1000 watts each...only available if placed by custom order as retail sale versions are 500 watt...along with 4 AB !200 watt amps with all powering a wide variety of 18 inch, 15 inch, 12 inch...and a few JBL horns used to reproduce the cluck or finger picking style of play.
Along with this is a Floor Moniter system of Duel JBL 15's and JBL Horns in each Floor cab and there are 8 of these along with Side Fill Moniters...2-18's...4-15's...4-12's and JBL Horns...on each side of the stage powered by AB Pro Series 2012 Amps...custom ordered.
Now all of this is just stage personal equipment and has nothing to do with the Hung P.A. of which we have 2 full systems that can be made into many configurations. EVERYTHING...is IDIOT PROOFED as cable connections are all color coded...sized and snaked as depending upon what configuration we use...there is a seperate snaked cable system for both sides flying and specialized junction boxes as well EVERYTHING is Computer Controlled as far as Analization done first to get the needed settings for EQ, Effects, Compressor Limitors and now even the Electronic Crossovers are Computerized.
All this said...at 400 Cycles to 0 are frequencies the Human Ear cannot hear...and between 0 and say 800 cycles...a person FEELS the sound more than hears it as such a system is pushing a large amount of Air Mass. What we have found is that if we boost low end at 200, 400 and 550...then add a boost point at 850...but adjust crossover output so that 850 cycle frequency is boosted in the 15 inch speakers and that 200 and 400 boosts are coming from just 18's....there seems to be a frequency overlap or perhaps a specific way the air mass is being pushed and thus transfering kinetic energy.
When this happens...People start getting SICK! And I mean...Puking, upset stomach, bowel movements...the works. I have been told by some people learned in Sound that this is highly unlikely but for us in the business who work with such massive equipment....WE KNOW IT TO BE A REALITY.
