Hi Curt--
To me, the "simplification" you have achieved is very elegant, if not
an invention. Anyone can build a rig like your's and start exploring
boundary effects for almost no cost. But there's a lot more going on
with your rig than "copying." One of the things I hope to learn this
Fall when we study the rigs in the field recording class is how
corner capsule location affects phase cancellation. Without your
rigs, we'd have no other approach to compare with Crown's. Rob D.
