There?s a lot of advise on sub placement including the crawling in the room method. I want to know if there?s is any general guidance on placement vs sitting position. I think I once read something on the drawbacks of sitting position being in the middle of the room. My room is 7.4 x 4m and main sitting position is right in the centre of the room. Where would it be recommended as optimal placement as a function of my sitting position?
