Well, I guess that you could say that speaker efficiency is one parameter to consider. Perhaps the most important parameter is the frequency response curve that shows the speaker's characteristics. Not all speakers are built the same with different drivers and cross overs coupled with a different enclosure mass and volume.

I'll bet that Alan could go on and on and on about differences.
