Compact High-Efficiency Compression Driver Design
The B&C DE111 has been engineered to provide professional high-frequency performance from a highly compact format. Featuring a 25 mm (1 inch) throat diameter, the driver integrates easily with numerous professional horns and waveguides used in compact sound reinforcement systems.
Its small physical footprint makes it particularly suitable for applications where enclosure space is limited while maintaining the output capability required in professional environments.
The driver delivers 107 dB sensitivity, enabling high acoustic output with efficient amplifier utilization. This high efficiency makes the B&C DE111 suitable for portable sound systems, compact stage monitors, installation loudspeakers, and lightweight professional audio products.
The compression driver architecture promotes efficient coupling between the diaphragm assembly and horn structure, contributing to controlled directivity and excellent acoustic performance.
High-Energy Magnetic Circuit Technology
The B&C DE111 incorporates a carefully engineered magnetic structure optimized for efficiency and diaphragm control.
The motor assembly generates an impressive 1.8 Tesla magnetic flux density, providing strong magnetic force for precise diaphragm movement and improved transient response.
This powerful magnetic circuit contributes directly to the driver’s excellent sensitivity and helps maintain low distortion characteristics during demanding operation.
Accurate diaphragm control is critical for high-frequency reproduction, particularly in professional environments where high output levels and continuous operation are required.
Combined with the lightweight moving assembly, the magnetic system helps maintain consistent performance across the driver’s operating range.
Advanced HT Polymer Diaphragm Construction
The B&C DE111 utilizes an advanced HT Polymer diaphragm, engineered for long-term reliability and smooth acoustic performance.
HT Polymer materials provide excellent thermal stability and durability while maintaining the lightweight characteristics required for high-frequency reproduction.
The diaphragm design contributes to improved articulation, accurate vocal reproduction, and smooth response characteristics across the driver’s bandwidth.
Its lightweight construction allows the driver to reproduce high-frequency content efficiently while maintaining controlled transient behaviour.
The diaphragm assembly also provides dependable long-term operation for demanding professional applications.
Large Diameter Voice Coil Assembly
The B&C DE111 features a 36 mm (1.4 inch) aluminium voice coil optimized for efficient operation and reliable thermal performance.
Aluminium winding material reduces moving mass, improving transient behaviour and helping preserve high-frequency detail. This contributes to improved clarity and more accurate reproduction of complex program material.
The voice coil supports 25 W nominal power handling and 50 W continuous power handling, making the driver suitable for numerous professional sound reinforcement applications.
Low inductance of 0.14 mH helps preserve upper-frequency extension and contributes to smoother frequency response across the usable bandwidth.
The combination of efficient materials and robust construction helps maximize long-term reliability.
Extended Bandwidth Performance
The B&C DE111 provides an operating frequency range extending from 1 kHz to 17 kHz, allowing the driver to cover a broad range of professional high-frequency applications.
Its lower frequency capability provides additional flexibility when integrating the driver into compact two-way systems and multi-way loudspeaker platforms.
B&C recommends a crossover frequency of 1.2 kHz, allowing designers to utilize lower crossover points while maintaining reliable operation.
The broad operating bandwidth contributes to excellent speech intelligibility, improved vocal reproduction, and natural musical performance.
Professional System Integration
The compact dimensions and lightweight construction of the B&C DE111 allow integration into a broad range of professional loudspeaker products.
Typical applications include:
- Compact two-way loudspeakers
- Portable PA systems
- Stage monitoring systems
- Installed sound systems
- Column loudspeaker systems
