No I have not heard of this program before but it does sound interesting.I am interested in learning more about it ,would you by chance have a link?Fred,
Have you seen the program CARA before? It's an acoustic modeling program.
You design up your room in 3d and it can calculate what the frequency response will be at the listening position. It also has a cool feature that shows where peaks and valleys will be in your room for a given frequency.
You could use something like this to experiment with different options before commiting to anything.
