B&C DE10-8 1" Mylar Horn Compression Driver 8 Ohm 2-BoltB&C's DE10-8 1" high frequency compression driver is small and efficient, yet does not sacrifice fidelity. Its smooth, brilliant output extends to 18,000 Hz, and is accurate yet non-fatiguing. The DE10-8 is perfect for compact 2-way loudspeaker systems, as well as the tweeter component in larger 3-ways. Although engineered to excel in demanding pro audio environments, the DE10 is also the choice of many home audio high-efficiency speaker enthusiasts.

B&C Speakers' line of compression drivers is the result of a continuous research effort, dedicated to refine every component in the structure, and their overall balance. Diaphragms are made of titanium, or mylar, or both, in order to get the required results in efficiency and bandwidth. Their shape and structure is mathematically evaluated well before building the first prototype. Afterwards, their performance is tested with methods that range from modal analysis to laser vibrotomy.
All voice coils are of the edgewound 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 is constantly improved by the progress in acoustical modeling and simulation.
