Rodman99999, on just about every speaker that I can think of, the suspension gets stretched as the speaker diaphragm moves away from the resting point. Furthermore, the speakers that have the most back EMF, i.e. the ones that are the most reactive, tend to be high efficiency designs, not low efficiency. In most high efficiency designs, the speaker is usually moving less, not more, due to the nature of the design.
The back EMF of such speakers is often the reason that amplifiers with large amounts of feedback (and often higher 'damping factors') usually sound more shrill on these speakers, as the back EMF becomes an unintended part of the feedback signal.
This is probably not what you would have initially thought. I know it was not for me! It turns out to get highly reactive speakers to calm down, you need an amp without feedback, i.e. low damping factor. In fact what you start to get about this is that the damping factor is for the most part irrelevant, whereas the amount of loop feedback is (the less the better).
So anyway, the issue of stopping the mass of the speaker is almost non-existant, unless you intend to amplify non-linear /non-musical signals. An example of that might be a linear motor in a disk drive. Damping in a situation like that would be quite important as the driving signal is not a function. But for audio, the amplifier is always sending the speaker a signal (power), and this power is always moving the cone incrementally in a new place.
To be otherwise suggests that the signal is not a function (which it has to be by definition). Like I mentioned before, the amp does not push the speaker to full excursion and then 'let go'. Since the signal is a function the cone is literally under power all the way back to zero and then beyond.
When I started this business I believed in damping and a lot of other things that I later found to be made up. I was fortunate though that I had enough exposure to the right classes in college and had read enough texts from the 'old days' that I was encouraged to look past the 'company line' to see what was really up. Turns out there have been two design paradigms in conflict in audio for a long time:

And I definitely subscribe to one and not the other, just like everyone else in audio :)
