The architecture of the mouthpiece is partially based on the density of the 
material.  Weight vs. volume, if you pack the weight into a smaller volume with 
a denser material (metal), then the mouthpiece is smaller.  If you have a 
mouthpiece with no mass, it doesn't transfer sound as efficiently.

I'm not real sure I believe that.....we've been doing some  
experiments, and are finding that if you build the same design in both  
brass and hard rubber, there's not
a lot of difference.....the rubber seems to "ring" a little  
more.....now before anybody starts with the "double blind scientific  
analysis" stuff, no, we don't do it that
way.....our experiments are for our own use, not general research for  
publication.....we're pretty satisfied we're on to something.....
