A question I have in that regard on my professional system is my mixing position, I do sit much closer to the front left, center, and right speakers as does most every mixer I've ever seen. So my question is the disconnect between the mixing position doing the original object based mix and the Dolby listening chart you have posted that shows an end listener sitting in the middle of the room? Thanks
No, DOLBY is well aware that a forward mix position would be more common in a mixing arrangement (especially multi-use), resulting in a more orthogonal layout than an equidistant layout. You still need to hit 85db + 20db headroom (minimum) at the listening position from all speakers, so if you have some distance to your rears, they better be capable of sufficient volume. Your processor will ensure equal arrival time. From experience, watch the side reflections from the rears if a lot farther away. It will affect tonal balance and the processor can only do so much.
