I think you'll find that "sensitivity" is a measure of how much sonic 
power a speaker generates for a given amount of electrical power. It has 
nothing to do with distance dissapation...

I was thinking more that being heavy allows the speakers to generate low 
frequencies more easily. (Otherwise the driver might end up just 
wiggling the cone one way and the casing the other way, and not 
producing much sound.)
