I have several hundred hours on my AN12 cast frames and absolutely they improve with break in. They are running open baffle and crossed over at 70Hz @ 24dB slope to let a pair of Goldwood 18's do the lows. While not perfect they are damn good up to respectable levels. At silly levels (that's when the dogs leave the room and the neighbors call the police) they do break up and have me headed for the volume knob. By all accounts the AN15's are better in most respects and worth the added cost.

FWIW, if my ancient Klark Teknik chart is accurate, then 'edge' is in the ~octave centered around 5 kHz, which the published response indicates, so my SWAG is it's a byproduct of the whizzer and shouldn't audibly change over time, ergo for whizzer 'enhanced' drivers the $0.98 or other tweak to damp them somewhat is virtually always required for HIFI apps.

I did a Gated Sweep with LMS on the AN12 Cast Frame once. At 5kHz, there was some loud cracking sound. I think that's where the transition of the whizzer comes in.

Cracking sound? Bloody hell. Are you sure that the drivers were not damaged or faulty?
I would have asked David to replace them.
I have not heard anything remotely like a cracking sound on either the 10 Neo or 15 castframe

You don't need to do gated sweep to hear a cracking sound.
Gating is used to avoid measuring room refections. It is a measuring technique

YES!

The gating happens in the measurement software, i.e., ARTA or HolmImpulse (and many others).

Read ARTA's user's manual and application notes. Very helpful in understanding these concepts.
