Most people could care less about specs and measurements. They just buy what they like based of whatever criteria they want and some companies just rely on that and marketing to sell stuff. Happens here all the time...surprise!.
That's the way most people buy most things and why advertising and PR have more influence on the general market than do logic or value. One would hope, however, that people with a deep interest and enthusiasm in a hobby might be more reflective. Guess not.
If your talking about the in depth detail that Stereophile go into when they measure speakers, it's because most don't have that kind of expensive measuring equipment/room, just the basics.
Sad, imho, but true. OTOH, there are many that do have the measurements but won't divulge them and others that are large/successful enough to do so but choose not to.
