You don't need to become an engineer. You do need enough reliable information to recognise what matters, what doesn't and when professional help is worthwhile.
Geometry, seating and the decisions that affect everything downstream.
Placement, coverage and integration without mythology.
Why the room dominates bass and why multiple subs can help.
What treatment is trying to achieve and where it can go wrong.
Brightness, geometry, aspect ratio and appropriate display choices.
Where processors such as Lumagen and madVR fit.
What professional calibration should actually accomplish.
Expensive decisions that don't necessarily create better performance.
The learning centre can ultimately host consumer education and a separate professional training pathway, without forcing beginners into advanced engineering material.
Understand the decisions that create a good theatre and become a more informed customer.
