That looks right except it'd be 5 doublings, so 110 dB SPL at 32m (or about 100 feet), or 104db SPL at 200 feet.
I wonder what the SPL would be for a "run of the mill" concert loudspeaker, as opposed to this "extremely high output" one.

There's also a time factor involved if you are assessing hearing damage potential, i.e. length of exposure. Not sure how to account for that. I suppose there are "loudness police" at concerts who monitor this sort of thing. Imagine the field day the lawyers would have if 500 people in the first 10 rows suffered hearing damage from a concert.
