Planars are not inherently better at delivering more linear FR. The roll of in bass is a function of the resonance frequency and unsealed front volume. Modify either and you get linear bass on a dynamic driver. Alternatively EQ cam get you there as well.

Rough treble can happen with planars just as well as with dynamics. also measurements up there are unreliable and smoothed, so you don't really know whats going on.

I never said we could get a KSC to sound like speakers (well in theory you could but thats like arguing that you could also in theory create a black hole on earth) or whatnot, I just argued driver types don't matter, FR does. Your ear does not give two fucks whether a tone is generated by bird, human vocal chords or a speaker.

Ah yes, your golden ears can hear the "overdampned" driver and presumably you can aslo hear the grass grow.

I'm out fam. People who think their human ears are the end all be all of measuring instruments, like you, are not the type if crowd I want to associate with.

I mean,TO MY EYES the earth is flat sigh.
