Playing a room where we are on a mezzanine and have a large (Casino) open space below us, we have a small dance area infront of us and I am running a Mackie P.A. with K.V. Audio powered subs. My problem is that the subs are definately cranking but if you go to the dance floor in front of us the subs are fairly much non-existant. I have checked all the relevant phase issues and that is not an issue, we play against a wall and I place the stacks about 1 metre from the wall, due to stage constrants, should I face the subs in another direction? It does sound like a phase issue at first but the further away you go from the band the more the subs slowly dial in to the mix. Dont have this issue with any other gigs we do so I'm figuring its the room. Any ideas?
