Sure. I'll draw something up tomorrow when I get home from work.Can you provide a screenshot of REW Room Sim that reflects the above room and sub positions, including any adjustments to phase/delay/gain?
Edit: The effect of a room mode on the listener is dependant upon the listening position. In some spots there can be massive gain, in others there can be no affect, and in others there can be cancellation (the null). Like the following shows. The relationship of those peaks and nulls along a rooms length don't change, just the frequency depending upon the room length.
