While I am likely misinterpreting things here, does the 425 have any such propensity for this frequency "climbing"; and might it be characteristic of most JMLC horns, as opposed to the 4001, A290 and presumably Troy's ES290 and Docali's mk3b2? OTOH, might electrostats and many high performance headphones also present the frequency range of musical signals this way?
I think the issue of 'climbing' is often overrated.
The concept of 'integration' is often conflated with what 'looks' to be close. Integration can take place for more widely spaced bands.
Meanwhile, waveguides are being compromised to meet these goals. This is not what I consider to be a balanced approach, and that can compromise the chances of success.
