I found this article today. Rather interesting.
“A speaker’s ultimate goal is “to sound like reality”—the elusive dragon that every audiophile chases—so on a broad, not-very-useful level, how close it comes to matching that reality is the difference between good and bad, expensive and cheap speakers. To be slightly more technical, the “spec” is clarity: The lower the distortion of the original sound it recreates, the better the speaker. In fact, basically every other spec, every confusing number you read on the side of a box is actually totally meaningless, according to both Steve and the Definitive guys. Steve singles out watts as “one of the more useless specifications ever created.” If you have to look for a number when buying speakers, Steve said one that’s “kind of useful” is sensitivity/efficiency, which would be something like 90dB @ 1 watt, which relates how loud a speaker will play at a given power level.”
There is more, but if you have ever had the pleasure of listening to your favorite music on a pair of high end speakers……..well, maybe you shouldn’t. It is like tasting fine wine and then having to go back to the cheap stuff.
