[QUOTE="Ivan Beaver, post: 109377, member: 30"] Re: Lumbar Array? A possibility would be as Jens said-but probably not the way he thought of it. If only the low freq part of the lower part of the boxes was being used, then the direction of the cancellation would be towards the stage-not behind the cluster as a normal "cardiod" configuration would be.. The spacing would be about right for the upper bass freq to try to keep some of that energy off of the stage. That could be good. HOWEVER the main direction of those freq would be in the opposite direction-or towards the ceiling-where you ALSO don't want energy bouncing around. So the upper freq (mids/highs) would be "pointed" in the right direction, but the lower mids/upper bass, would not be. So I would suspect the overall coverage would not be as expected/desired. As with many thing audio, when you "try" to fix one problem-you can do that-but you create another problem-that you may not want. It is all about compromise and what is more important. Of course I could be completely wrong-but this is based on the very limited information supplied for the "project". [/QUOTE]
