You may want to take a look at the wood conical sound diffusers that cover the back wall in the renovated auditorium at Alice Tully Hall in Lincoln Center. There is an article in the New York Times that appeared last Thursday. Go to nytimes.com/music. It is the first time I have seen such construction. Hard to estimate the height of the conical pieces. Not clear why a conical construction would work. Would not be hard to duplicate. Anybody have any idea what these will do?
