Klippel’s updated Max SPL (MTON) Module with ISC room compensation (lower your volume!)

Warning: Turn down your speakers!!! I play a multitone signal in this video so don’t crank your volume. ;)

This is a short and unpolished video showing how I am able to use Klippel’s MTON and ISC (in-situ compensation) modules to determine actual maximum SPL for a speaker in the far-field in my measurement room (insulated/temp controlled garage).

This is some next level stuff.

That's cool that you can adjust the frequency output to protect the smaller drivers.

If you have to stick to just one (60 vs 80 or even 100), I think 80Hz is a probably a fairer ‘midpoint’ compromise and should apply to a greater number of bookshelf type speakers.
