B&C Compression Drivers
B&C Speakers’ line of compression drivers is the result of a continuous research effort, dedicated to refining every component in the structure, and their overall balance. Diaphragms are made of titanium, mylar, or polyimide, in order to get the required results in efficiency and bandwidth. Their shape and structure are mathematically evaluated well before building the first prototype. Afterward, their performance is tested with methods that range from modal analysis to laser vitrectomy.
All voice coils are of the edge-wound ribbon type and made of aluminum to reduce mass and achieve the best electro-acoustic performance. The magnet assembly is designed and optimized with up-to-date software for Finite Element Analysis (FEA) and complemented, where needed, by a copper cap to improve frequency extension and linearity. Equal care is taken in the design of phase plugs, whose role in enhancing performance and reducing distortion artifacts is critical for compression drivers. The precision and transparency of B&C compression drivers are constantly improved by the progress in acoustical modeling and simulation.
