I’ve had some Martin Logan’s that had no treble fresh out of the box; perhaps the panel needed to be fully charged? I confirmed it with in room measurement.
So you provide a concrete example of a driver response changing after break-in, and then go on to conclude that since your sole anecdotal example could be inaudible (did you test?) to human ears you go on to conclude burn in is completely a “waste of time and energy”?
Seems like very shaky...
There’s nothing more annoying and immersion breaking than actually hearing bass come from the subwoofer’s location. Feel free to experiment but I would never crossover that high. 80hz or lower. Don’t chase tiny flaws in the speaker response that are swamped by room modes anyway.
Take your pocketful of money and go gain some actual experience listening to speakers, and use music you actually listen to. There is no substitute for it (especially forum advice).
Really surprised to see snobby audiophools bash a $100 speaker for not being linear enough for them.
As if the target market for these is some crusty old boomer asking his wife to come in and see if these are peaky at 1khz during his favorite violin concerto.
A better test for these speakers...
