The ATC's can be highly dynamic, but go ahead and call ATC if you like, they publish the maximum SPL is 117db at 1m, and at typical listening distances will be around 110db or less. Also note, the distortion figures aren't provided but I would wager it has peak distortion levels of around 10%. This is not to say across the audio band, just simply the highest level of distortion at any point across the audio band. The vast majority of speakers produce this at 20-250hz, but many exhibit audible distortion at 95db average levels in the mid or treble ranges. There are very few speakers that can achieve this kind of dynamic range, but bass drivers are typically massive to keep distortion under control with mid and tweeters often being horn loaded or in an array configuration to withstand the load.
The ATC design will produce a notable amount of distortion in the bass if driven, but being a doped paper driver and our lack of sensitivity in that audible range makes it somewhat negligible. Doped paper, while not really capable or producing a rigid diaphragm, is quite good with internal dampening and generally makes the system work well. Its lightweight makes cone movements easier to achieve with a given motor assembly. Those soft domes used in the large dome mid and treble drivers also follow the same ethos. Light and well damped, which is pretty reliable approach.
