Beetle -  the measurement that would likely reflect on what you are hearing is a radical zoom-in on the onset transient impetus. The shoulder will be cleaner / sharper. Similarly the top shoulder before decay will be cleaner and simpler. Deep knowledge of the interactions between capacitance, inductance and impedance reactenances and reflectances might predict what measurements might reveal - thereby guiding measurement and evaluation strategies. But when a company is developing products on less than a one per year cycle, such measurement luxuries must be budgeted. Over the course of tens of thousands of hearing / measuring cycles, we learned what to trust and what required further verification. Note that such engineering verification was directed toward analysis for future projects and products more so than optimizing the present product. Note the systematic thematic progress from 1976 to 2009. Lots of learning, standing on one's own shoulders, so to speak.

Thank You for posting the CS 2.4SE review by Jeff Fritz.
It serves as a reminder on my decision to purchase the SE above all other loudspeakers I auditioned from 2011 to 2014. To my ears, nuance, was the deciding factor. Hope you are having fun today with the XO project. Keep up the outstanding work.

Happy Listening!

Good to see you. Hope you are well and like beetle, having fun in your Hot Rod garage/studio, with your XO projects.  Keep up the outstanding work!

Happy Listening!

A pre and post measurement with Rew is not that much work and could give something tangible to support the subjective improvement or lack of deterioration. As I gain experience and understanding of this powerful tool, I'm less reluctant to pair my observations with measurements.

FWIW, I measured freq response of a tone sweep pre and post on axis and from the listening position. Now, the microphone was simply my iPad but both channels had the same handicap. All good. Well, there was a detour but not worth typing out the story :)

Tom has more sophisticated tools but his upgrade is not as far along as mine.

what is Rew?
