Too much lab, not enough listening?
One year at RMAF YG was distributing leaflets that they made the Best Speaker. Now as we English speakers know, The Best means there can be only One, so I figured it might be worth a listen :)
I brought a CD up to their room. I do not know the model, but it was a 2 1/2 way (tweeter, midrange and woofer, midrange mechanically crossed over).
The cut was the opening track of Peter Gabriel's 'Long Journey Home', the soundtrack for the Rabbit Proof Fence. There's a pretty big bass note in the first 30 seconds or so. When it hit, the midrange driver buzzed loudly(!) against the metal frame mounted in front of it. The amplifier, which was quite powerful, was putting out a bit of power and since there was no crossover to keep the bass out of the midrange, despite being mechanically crossed over, the midrange nevertheless had a lot of excursion.
I know of a number of speakers that can play that track effortlessly at a lot higher volume with less power. So I had to conclude that at that time at least, there wasn't only one.
Disclaimer: I've not heard any of their speakers since.
