Re A/B tests to determine the louder/better speaker:

    This is where speaker efficiency enters into the picture.  The more
efficient speaker (by definition) will be louder at the same setting of 
the amplifier volume control.  Just switching the amp from one pair of 
speakers to another is not a valid comparison unless the two speakers 
are equally efficient.
    Efficiency has little correlation with quality:  there are excellent
speakers of all different efficiencies (and lousy ones, too).  The better
speaker is the one which sounds better.  To determine this you have to
listen to them at the same volume, which means twiddling volume controls
if they're of different efficiency.  The practical difference is that you
may need a more powerful amp with less efficient speakers.
