Newbee, The OP states the speakers are almost placed across a corner. I take that to mean diagonal placement. If that is the case the majority of your post regarding speaker placement does not apply. The same is true of the Cardas program which does not work for the majority of people.
The OP knows the speaker placement is not ideal, but has constraints based on room layout and aesthetics.
