Have you used any kind of room simulation like in REW? Maybe it doesn't apply since you are doing the baffle wall but when I entered your room dimension and the seating distance I saw in one of your posts it doesn't look the best(big null around 40hz). It looked quite a bit better being closer with your seating. But I have no idea how accurate that is when using a baffle wall and I could have entered something wrong. Just thought I would mention it.
