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). |
