What does the term "Speed" mean in a speaker?


I often hear people say "That speaker has great speed". What do they mean? I know the music isn't playing at a different pitch. Could it possibly be related to efficiency?

I don't understand why manufacturers don't post 0-60 and 1/4 mile times?

It would make speaker selection much easier.
You can't be serious.  
I think it falls into what the Brits refer to as PRaT - Paced Rhythm and Timing. Of course Prat is also British slang for:
  1. an incompetent, stupid, or foolish person; an idiot.
  2. 2. a person’s buttocks.

I supposed this is another dumb joke.  Maybe you're number 1?
