According to an expert speaker guy, whom I don’t recall his name said 5’-6 is the magic number for speaker setup, the ear can pick up on the timing difference below this distance, so if your ears are 10’ from the speakers and a reflection path distance from a sound wave is 16’ then all is good, however if it’s less, then it will muddy the sound stage, so the if the speakers are 2’ from the back wall, we’ll that’s 4’ timing offset to your ears… so you pull them away 3 or more feet from the back wall to be greater than 5’-6… I think this would apply to the front wall too…
whose right… who knows… always fun to experiment though….
