Below there to the millimetre exact (+-0.25mm) are plans of the room, it's setup and it's mathematically calculated reflections.
The 100 rays are traced on first reflection order with an absorption coefficient of 0.01 which is usual for painted concrete walls @<=500 Hz.
Studio A might be small but it's been optimized for more than a year to deliver the best sound possible.

Above's plans construct an ideally angled room that does not exist in reality. Studio A's walls are both vertically variable (means they are not perfectly 90° angled to the ground, nor perfectly straight) neither are the room corners at a perfect 90° angle.
As a result the plans above are approximations that introduce minor deviations in the end result.

It's final calibration conclusion includes much more than the real listening spot.
Measurements were made nearly across the whole room, with a distance of about 1m to walls, from which SW Ref4 calculates an average at the end.
Sonarworks Reference 4 takes a lot of measurements into calculation in order to enhance phase response via a calculated average. Additionally it applies an EQ correction curve onto the speakers in order to make the frequency response more linear.
The final result is a wider sweet spot that deviates less concerning the frequency response for a more linear experience.
In the end however SW Ref4 still can't change overall physics.
So you should still stay within the listeners spot. Checking back on the mix without SW Ref4 at times might be beneficial, too.

As a result it is not a perfect equilateral triangle.
