Hi guys Looking to buy the new QSC k212c speakers to up grade from my old k-subs. Which have been excellent by the way. But need help. Were putting on a soul weekender for between 450-700 people. In big hotel ballroom. Question is there a sound formula per head of audience..I'm asking as not sure what sized sound system we will need. At the moment I'm using 4 x qsc k2/12's 4 x k-subs But feel fairly sure this is not going to he anywhere enough sound, esp for the back of the venue... Any constructive help gratefully received Thank you in advanced.
