Jupiter-
Just a comment. The graph you show is not a step response, the time scale (horizontal) for a speaker's step graph would be maybe a few tens of milliseconds. And the vertical scale on that is dB (no polarity info). A good step response would drop in a straight sloped line like that only when shown on a linear scale. I'd guess that is a graph of decay of room refections, or possibly a nearfield of a very ringy speaker!
On some other discussions in this thread: an acoustic suspension woofer has a 2nd order highpass response, so can only approach time waveform coherence at frequencies much higher than the woofer's f3 cutoff. A very low Q alignment (sealed or OB) can approach linear phase but hard to get deep bass from.
