thanks for all your help and advice. sounds reasonable. i'll keep the subs together instead of each side the stage or in a row along the floor. sometimes the tops will be on each side, but that's ok isn't it? subs together on the floor, tops on each side maybe 10 or 20 feet apart. that's ok isn't it? what would you do with a 20 foot wide stage and a 50 foot wide room?
