The Børresen DCC5s driver
The Børresen DCC5s driver is developed with a clear objective: to achieve low distortion, fast transient response, and a high degree of control through careful optimization of both the diaphragm and motor system.
At its core is a multi-layer diaphragm consisting of an aramid honeycomb core sandwiched between two carbon fiber skins and bonded into a unified structure. This design combines high stiffness with low mass, enabling precise movement while pushing resonances beyond the driver’s critical operating range. The result is lower distortion and a more coherent overall presentation.
The motor system is engineered with equal attention to detail. A ferrite magnet structure provides strong, stable magnetic flux, while dual copper caps reduce inductance in the voice coil gap. This improves linearity, lowers distortion, and enables a faster, more precise response to the input signal.
The DCC5s driver also utilizes a titanium voice coil former. Its high rigidity and low mass improve structural stability and response speed, helping the diaphragm follow the signal with greater precision and minimal energy loss.
By combining a lightweight, high-stiffness diaphragm with a low-inductance motor system, the DCC5s driver delivers controlled, responsive performance. The result is clean, detailed, and dynamically accurate sound reproduction with exceptional clarity and coherence.
