Snofun3: "Ohm rating is not an indication of goodness or badness, it's a measure of driver efficiency.
A 16 ohm speaker will take more amp power to drive."
Right, wrong, and wrong.
Absolutely, nominal impedance is NOT a qualitative measure of a speaker system.
System impedance is NOT an indicator of speaker-system efficiency or sensitivity.
High-impedance systems generally consume LESS amplifier power.
I think Twl correctly stated the meaningful differences.
