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

I think there's a big gap between a speaker that sounds fast, and a driver that IS fast.

I mean, there's a lot of reasons for speakers having more detail or jump factor. The actual transient response of the drivers used does not really contribute to all of it.
How the speaker mates to the room, and frequency response I think are probably the first two things the casual listener associates with speed.

That's fine, nothing wrong with that since the end result is what matters.

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’m pretty sure it was a joke

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.
