Dave did not really design these mouthpieces as an entity in itself. It is part of a complete system. When I buzz, it is on my non Prana B2D mouthpiece for the same reason.
The lips can only vibrate in a controlled manner if they have close to equal "pressure" on both sides OR if the muscles have enough strength to overcome the imbalance. Your diaphragm provides the inside part, the mouthpiece, horn, room provide the outside resistance/impedance.
The most recent Pranas are a pretty radical departure from conventional mouthpiece construction. I choose to use them only where they work best - in the horn.
The funny thing is, that a mouthpiece can be free blowing by itself and have normal impedance when in the horn. That is an issue for Dave Monette or physicists. I am happy that the new generation gives me a lot more for the same input of energy!
