James: cool design not all that different from the big Void cabinet, nice work. Did you happen to have a look at the klayman patent above? US #5, 177, 329.

number brought up a noise-cancellor - is that the intended patent? why might prior art with physical resemblance prevent a new patent for Danley who has a firm grasp of how to apply something to good effect which may have escaped full understanding in previous ages?
R-J reflex get re-invented every so often and new patents are granted |

thanks - I don't have credentials nor smarts to properly analyze a case but that seems to be a marraige of refelx to transflex to create a type of bandpass enclosure.
a simulation program with enough mobility to do mutual load cases would be fun |
