Specifications

While it is obvious to anyone who has listened to many speakers that numbers and specifications are completely incapable of predicting what a speaker will sound like, it is still useful to know some basic parameters. They are not so much useful for comparison, but to decide if a given speaker meets your general requirements.

And of course, dimensions and weight tend to be pretty useful!
