Romy,
Are you currently implementing "nominal" 3200Hz x/o on the mid range channel S2 using a cap at the driver? I know this works nicely to ameliorate the "secondary" resonance of the plastic edged diaphragm.

Reason I ask is because things may not work quite the same with the scheme above - some of the response shaping of the 3.9uF (or whatever it was) cap at speaker level may be due to an interaction with the S2 inductance etc, which you wouldn't get if the S2 were a textbook resistive load (as seen by the 1500pF cap in the 6 ch Melq).
Yes, I know and consider it, it would not be difficult to tune the cap to se the S2 to response properly. However, there is a bigger fish to fry in here. If you remember in my 3 channel Super Mils I was not able to use line level high-path between the stages in my HF chennal as it sounded very wrong. I still have no explanation why. I just hope that it will not happen with the single-stage amp.
