Loudness management is OFF, dyn EQ ON, dyn volume I am playing around with it, but normally light or medium. When off there is just too much difference between quiet and loud scenes. Good in a cinema room in a detached house, not very sustainable in a semi!
More than anything else in anything else I always had trouble with the center channel - and it is still the case with the C350. Audissey always always always sets it too low. Normally to get speech not overwhelmed by everything else I have to increase center at +5db compared to what Audissey gives. I read elsewhere that that is often the case? It happened to me with every single set up and AVR with Audissey.
With the center channel at +5db and Dyn vol at light I have a very consistent listening experience, without loud bangs and inaudible speech. -17dbs give or take.
