Earl, if you are saying that you are not interested in using this program, I can accept that. You don't have to use it. But if what you are saying is that you are not interested in hearing Dr. Thomanek's explanation of how it works, as a reply to your arguments that it might not, I cannot accept that. You are the one that challenged its accuracy, so you are the one that should defend your accusations.It looks like CARA may be a very useful program for people interested in finding the best placement for speakers in their homes. If you are interested in educating people on where to place speakers for best sound, don't you think it would be good for them to be able to see for themselves?
