High Efficiency Speaker Asylum

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

mean speaker are more or less efficient here?

Do they have to work harder to move the same mass of air as they would at sea level?

Gotta be SOME audio benefit from living where there are so few molecules of oxygen in the air.

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.
