Sound projection

[Keith A. McGavern]

I had a church customer ask me if putting a piece of plywood on the back of
their console piano would project the sound further.  Apparently someone
told this customer it would.  I have never heard of this approach.  Anyone
here on Pianotech have any practical experience with this concept?
