Hi browndk26, I would start in the right front corner. This will help maximize the conservative output of the sony sub. (If that's still what your using). If it's too tight in the corner, it may sound "boomy", and "one note"-ish. This is where moving closer, and farther from boundaries becomes important, as experimentation will allow you to know for sure. However, to be frank, many htib subs will sound that way no matter what. Not a knock, just speaking to their design compromises. Room looks nice!
