Despite the incorporated protection (thermal overload, ABL) - which I might point out no passive speaker has - I would think if you punish it enough, for long enough, amplifier clipping or more general overheating of the voice coil could destroy a tweeter.
Being an 'ex' audiophile I exercise caution - in a listening room 5 x 4 metres, I seldom go above 55 on the volume for music, and 60 for movies.
In moments of gay abandon, I've cranked it to 62 on movies and large organ works - but that's about it, as any more and I would be inviting a visit from the PC neighbours, or their agents, the police....lol
And at that consistent volume, I've had no issues.
By way of contrast, when I bought the speakers and demoed them in a private after hours demo, the dealer cranked it to 82 on clips of the movie Avatar with no deleterious effects - but then that was in a large showroom, and there's no way I'd listen at that level at home.
So my thoughts are that the speaker is much better protected against overload than any speaker operating in passive mode with a seperate amplifier, but there will inevitably be limits, sooner or later.
