Wall to wall reflections tend to disperse. Most room resonences are corner to corner (in a box-like room). Sound behaves a lot like light in a three-way right angle corner - It comes back out the same direction it went in, just like those three way mirrors they use to reflect laser beams back from the moon. Most studios these days try to avoid any right-angle corners. e. j. branagan The MUSE - Nashville, TN
