Interesting. That would help explain some of the differences in burst response between v1 and v2, or atleast decay because otho walls are shifted. V2 has an ortho wall at @4800 so burst response decay is going to be longer lived (@4800). Doesnt mean v2 sounds slower in general in upper mids or treble vs v1, just at @4800. Do the measurements correlate with what you hear subjectively? Preference for v1 or v2?
