Two-Way Coaxial Headphones

[JSHamlet234]

As I look at the measurements of over-ear headphones, I can't help but notice that basically all of them seem to suffer from cone breakup in the mid to upper treble. Am I correct in that presumption, or is the jagged treble perhaps the result of inherent flaws in the measurement process? Has a 2-way coaxial ever been attempted? I can't recall any.

I keep wondering about coax drivers too. The recently released blon bl30 with 70mm drivers got me thinking about it again. Theres room for a 15mm driver in center structure of those.

Never seen a 2-way coaxial before, but there are multi-driver hybrid designs, typically with different topographies. I don't think the multi-driver designs have really measured any flatter than single driver ones but maybe that wasn't the goal per se anyway, maybe just lower distortion.
