I don’t know of any manufacturing model that is based on no profit. The model you are proposing would not be profitable and eventually fail, probably rather quickly.
Its not a model designed to make money. That is exactly the problem with speaker design. Its based primarily on maximizing profit. My technology would be based on meeting the needs of each and every audiophile. It has nothing to do with profit. Why shouldnt it be profitable? If the customer was present while the crossover was being tuned by the designer, he could then state his preferences based on what he was hearing and that would then determine the final crossover circuit. Why is that so hard to implement? How many people in the world wear eyeglasses? Millions. Yet we can somehow manage to get each and every one of these patients into the office for an eye examination and then fit them with custom tuned lenses. If we cared about sound just as much as we do about vision then perhaps it would be workable?
