What does "dynamic" mean?

[j0nnyfive]

Okay, thanks again for helping me with this guys.

I've been looking for information on impulse response. What it means, how it affects sound, etc. I'm having a hard time finding something that isn't calculus heavy. I understand the dynamic compression idea. Can you explain to me how one of the most dynamic speakers can have a sens of 89db? I think if I understand this, I'll "get it".

Update: I just found a site that says that impulse response is basically how gracefully a driver settles down. Is that about right? Does waterfall measure this? And, how is this response affected with increased power? Trying to connect the dots. I'm wondering if "dynamics" with impulse response can be talked about separately from "dynamics" relating to compression?

You don't have to answer all that, I just wanted to show you my thoughts (hope it doesn't sound too crazy).

Thanks always!
