Thank you for the post guys and sorry for not being more clear. As @onhwy61 mentioned my room is almost a cube at 10’ l x 9’ w x 9’ h. Note that the back wall behind me is 36" tall, above which the space opens up to my family room and kitchen. Because the room is almost a cube I cannot tell from which dimension the axial mode is coming from.
I know that my Right speakers has peaks at 60/120/180 and since I sit with my back right against the short back wall, I have to believe this is being caused by the length axial mode which has max volume of all the modes at the extremes. What I dont understand is if I want to try to address the length axial mode should the bass trap go directly behind the speaker or on the back wall behind the seating position? Even though the back wall is only 36" tall, it is only about 2" lower than my ear height.
@geoffkait I am not sure I understand what you are suggesting. I measured my room response only from my listening position so isnt this where the wave is?
@erik_squires and @bdp24 I do use EQ with REW. I found that peaks are dealt with effectively with EQ but dips do not improve much.
