Recovered conceptual route; complete prerequisites and flagship-quality capability are unverified.

Making outline

Assemble copper-coil moving diaphragm speaker with permanent magnetic circuit
Research detailed preparation, operation and acceptance. Numerical limits and suitability are not specified.

What remains unresolved

A voice coil alone is insufficient: magnet, membrane and air paths remain essential.
Exact grades, quantities, operating parameters, tolerances and complete making dependencies are not finalized.
Candidate method, complete inventory, caller demands and physical compatibility require research and review.

Unselected discovery proposals

These are research questions, not published manufacturing dependencies. The seed combines alternatives, operating requirements and verification relationships.
