Looking also for something to get real dynamics
ATC 100ASL will certainly be more dynamic than most other conventional box speakers - close to "real dynamics" but still not able to do justice to a jet engine. The only things that can play louder cleanly would be other large studio horns or a bigger ATC's or something similar like Hans Zimmer's 80K per speaker Quested's
Of course you could try Meyer horns like this and you'll definitely have close to a real jet engine but for better sound quality than Meyer sound reinforcement gear you might try Westlake's Studio speakers which can be setup in active mode too.
In any case, put on an uncompressed drum track or good recording and you will appreciate the real dynamics that only big speakers with pro woofers can produce (it can be jaw dropping - and it won't seem "loud" in the normal sense - these designs remain completely effortless sounding throughout their operating range).
