We run our own P.A. for most of the shows we play and we've had some gigs recently where our BL has elected to put the subs on the stage instead of the floor (or ground, when playing outside). In one case (last weekend) the "stage" was a flatbed trailer meaning the subs were about 3 and a half feet off the ground. IMO this definitely affects our FOH sound (for the worst) and my belief is that subs ALWAYS belong on the floor/ground or as close to it as you can get. The BL doesn't think it matters that much. Hence the disagreement. He has a good ear for sound and we get along well on almost every other point so if it doesn't really matter I'm not going to fight him on it... but OTOH, this is a facet of our sound that we can pretty easily control, so if it does make a difference, then I'm going to start taking a harder line on this with him in the future. FWIW, the subs in question are Yorkvilles loaded with 2 18's. Thoughts?
