I agree with most of the theories above for sure. I also agree that the room acoustics have a lot to do with frequency dispersion and speed. To much absorption and or diffusion will have a profound effect on the fastest speaker production.
It is unfortunate fact for all of this as it really difficult to find the perfect combination without serious experimentation and or expense. I am fortunate to own full ribbon driver speakers and have had all types before them......they are easily the fastest I have experienced because of driver mass and height of the panel allowing driver radiation accuracy. In addition, I have experimented with acoustic treatments extensively (both absorption and diffusion) and feel they do pretty well with minimal treatment accept for my room's obvious modes. Nothing will be perfect so you have to choose the combination that pleases you most in the overall selection of components, speakers, and room acoustics. Everyone has different thoughts in perceived musical reproduction.
Best of luck,
