Compact High-Efficiency Compression Driver Design
The B&C DE5 has been specifically engineered to provide professional high-frequency performance from an exceptionally compact package. Its 13 mm (0.5 inch) throat diameter allows it to integrate easily with compact horn designs while maintaining excellent acoustic loading and efficient sound radiation.
The driver achieves an impressive 109 dB sensitivity, enabling high output levels with relatively modest amplifier power requirements. This high efficiency makes the B&C DE5 particularly suitable for portable sound systems, compact loudspeakers, and installation projects where maximizing performance is a priority.
Its compact dimensions allow loudspeaker designers greater flexibility when developing space-efficient loudspeaker systems without compromising high-frequency performance.
The result is a compression driver capable of delivering detailed and articulate high-frequency reproduction while occupying minimal space within the loudspeaker enclosure.
Advanced Magnetic Circuit
At the heart of the B&C DE5 is a precision-engineered magnetic circuit designed to maximize efficiency and diaphragm control. The motor assembly generates an impressive 1.65 Tesla flux density, providing strong magnetic force and accurate control of the moving assembly.
This powerful magnetic field contributes directly to the driver’s high sensitivity and excellent transient response characteristics. The motor structure allows the diaphragm to respond quickly and accurately to incoming audio signals, preserving detail and articulation across the driver’s operating bandwidth.
The optimized magnetic circuit also helps maintain low distortion characteristics, ensuring that vocals, speech, and musical content are reproduced with clarity and precision.
Combined with the lightweight diaphragm assembly, the magnetic system enables the B&C DE5 to deliver professional performance despite its compact size.
Lightweight Mylar Diaphragm Technology
The B&C DE5 utilizes a carefully engineered Mylar diaphragm designed to provide excellent durability, consistent performance, and smooth high-frequency reproduction.
Mylar is widely respected for its combination of low mass, mechanical stability, and reliability. These characteristics allow the diaphragm to respond rapidly to dynamic signal changes while maintaining accurate reproduction of complex musical content.
The lightweight diaphragm contributes to the driver’s ability to reproduce frequencies up to 18 kHz, ensuring detailed high-frequency performance and excellent vocal intelligibility.
The robust construction of the diaphragm assembly also supports long-term reliability, making the B&C DE5 suitable for professional applications where consistent performance is essential.
Precision Voice Coil Assembly
The B&C DE5 incorporates a 25 mm (1 inch) aluminium voice coil designed to provide an excellent balance of efficiency, low moving mass, and thermal performance.
The aluminium winding material reduces moving mass, improving transient response and allowing the diaphragm to reproduce high-frequency information with greater accuracy. This contributes to cleaner sound reproduction and improved detail throughout the operating range.
The driver is rated at 10 W nominal power handling and 20 W continuous power handling, providing sufficient capacity for a wide range of compact professional loudspeaker systems.
The voice coil assembly also features a very low 0.1 mH inductance, helping preserve high-frequency extension and ensuring smooth performance throughout the driver’s operating bandwidth.
Extended High-Frequency Performance
The B&C DE5 is engineered to reproduce frequencies from 2 kHz to 18 kHz, making it suitable for a wide range of professional sound reinforcement and installed audio applications.
Its broad frequency response allows it to reproduce critical vocal harmonics, speech intelligibility information, and musical detail with exceptional clarity. This makes the driver particularly effective in applications where accurate high-frequency reproduction is essential.
B&C recommends a crossover frequency of 2.5 kHz, allowing seamless integration with compatible low-frequency and midrange transducers. This flexibility provides system designers with numerous options when developing compact two-way and multi-way loudspeaker systems.
The combination of high sensitivity and extended frequency response enables the B&C DE5 to deliver impressive acoustic performance across a broad range of applications.
