Dynamic Range 20-20K

Yes, you can also do that with REW, by measuring things like impulse response, but on the hardware side, you can look at the slew rate specs. Slew rate of modern electronics is generally a solved issue though.

Here's an easy to read an old article on Slew rate by Steve Munz of Audioholics.com, it included an Editorial by an Electronics Designer for Classe :

Slew Rate in Audio Amplifiers - What Does it Mean?

With the Classe gear you are using, I highly doubt you have to worry about "the speed in which it takes to get there", you just have to make sure your amps have more than enough voltage and current your speakers need to get your the maximum SPL you need at you seats without clipping, or excessively high distortions+noise.

Much appreciated, I am on this as soon as I can.

Don't worry about speed unless the distance between the speakers and listener(s) is very large and even then, it would only matter for eliminating delays between multiple speaker cabinets, as in, a large venue show. In a room, the best way to see how well the output from all drivers is aligned in using impulse tests or wit pink niose, REW or some other accurate spectrum analysis, showing phase cancelations as deep dips in the response where the response at the crossover frequencies coincides.

I meant the time it takes (slew rate) for each driver to reach its dynamic capabilities.

You're still misusing the dynamics term it seems.
