Sounds to me like it would be on the short list for massive symphonies, oratorias, cantatas, opera, and at the other end, vocal solos and ensembles.
FYI - That 2013 sale of Bob Carver Corp. to 'Emotiva' was negated after a few months, so it is now back under Bob's ownership.
The thought of a speaker having the headroom to deliver distortion-free 120 dB crescendos really grabs my attention.
