My definition of efficiency might be a little different from others but its not just the max rms power...its the entire range. I consider the infinities "efficient" because their rms range is 2-90 watts which means you can power them off any thing from a crappy tape deck to a good amp. Other ones like MB quart i consider not as efficient because their rms range is like from 60-120 watts rms which means it requires an external amp.
