To be honest I no longer believe that the Wavelet diagram will tell much about the dynamics (or maybe we shall call it transient response?) of a speaker
Well, it's odd that you would say/guess subjective "dynamics" to be directly what "transient response" means... since the wavelet spectrogram plot you had previously used does faithfully show the frequency-time components of your captured/measured impulse response i.e. transient response as measured at a given single point in space -- but, then, you've also selectively heavily biased it to show mainly the time aspect of it all which kind of defeats the purpose it was derived for in the first place. Remember, speaker manufacturers take many, many measurements -- off-axis points included.
Of course, a speaker's directivity performance matters a lot and should not be neglected. As you said so yourself: larger drivers seem more "dynamic" -- ask yourself what is the relationship between driver size and directivity in a given performance space... Well, whatever this notion of speaker dynamics is, I think it is only fair to consider both transient response and directivity as (at the very least) part contributors.
