Not sure how you'd specify bandwidth or crest or...?

I'd like to see the specified useful frequency response range actually used for specified peak power testing, without driver damage or outrageous distortion from cone flap. I know my MRX525s can't go to 60Hz (or whatever the JBL spec is) at anything close to the specified 3200w peak drive level without flapping or likely self-destructing. Yet JBL chooses to rate the speaker with those performance figures, as if they are separate.
I'd also like to see honest power compression information, both how long it takes to heat up, and how much output is lost, at given drive voltages.

Yeah I see all that happening soon.

Danley has pretty comprehensive spec sheets compared to virtually every other manufacturer. I bet any additional information they added would not significantly change the fraction of customers who want to hear a demo box in action before they decide to purchase the box.
If it were, say, Bill Fitzmaurice DYI designs adding a bunch more informative, honest specifications with detailed explanations of measurement methods, I imagine it would discourage some purchasers.
JBL is certainly somewhere in-between, and does not respond to questions like, why don't they correct large, obvious errors in the spec sheets. So, I guess JBL figures spec sheets aren't a big contributor to loudspeaker sales?
Interestingly enough, the ASB6125 cut sheet indicates it is loaded with the same woofers as the SRX725. Obviously the box is not the same.
