RE: So does the reduced mass of air for a given volume (fewer molecules of air per cubic in/ft/meter)...

Air density determines the impedance load presented by the air. The higher impedance of denser air creates a more efficient energy transfer. It's the same thing that makes horns work. The higher air load impedance of a throat area smaller than the cone along with the mass of the air column creates a more efficient energy transfer than directly coupling the cone to the air.
