I was trying to be funny by agreeing with you. The main criticism WAS about pulling up ancient threads, whether or not the info was accurate. Sort of "Yes, and your point is...?"

To address the subject, I believe a simpler explanation would have been better in order to be understood by someone who needed to ask the question. It's better to impress the one who asks a question than to impress others who already know the subject at hand.

Simply put, speaker sensitivity is the efficiency with which a speaker system converts watts of electrical power to decibels of accoustical loudness. It is dependent upon both the electrical and mechanical properties of the speaker drivers and the enclosure construction.
