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. Randy Hudson {harpo,ima}!inmet!rgh
