Advanced Compression Driver Architecture
The B&C DE250TN has been engineered to deliver professional-grade high-frequency performance while maintaining excellent efficiency and reliability. Its 25 mm (1 inch) throat diameter provides compatibility with numerous professional horn configurations, allowing easy integration into a broad range of loudspeaker designs.
The compression driver architecture promotes efficient coupling between the diaphragm and horn assembly, improving acoustic loading and enabling excellent output capability across the operating range.
With a sensitivity rating of 106 dB, the driver produces strong acoustic output while maintaining efficient amplifier utilization. This makes the B&C DE250TN particularly suitable for high-output systems where maintaining efficiency is critical.
Its professional architecture allows the driver to operate effectively across portable, installed, and touring audio applications.
High-Energy Magnetic Circuit Design
A defining characteristic of the B&C DE250TN is its powerful magnetic system, engineered to maximize efficiency and diaphragm control.
The motor assembly generates an impressive 1.85 Tesla magnetic flux density, significantly contributing to the driver’s strong sensitivity, fast transient response, and precise diaphragm control. The increased magnetic strength allows the diaphragm assembly to respond rapidly and accurately to incoming signals, improving detail and articulation.
A high-energy motor structure also contributes to reduced distortion levels during high-output operation, helping preserve vocal clarity and musical accuracy even under demanding conditions.
Combined with the lightweight moving assembly, the magnetic system enables the B&C DE250TN to maintain consistent performance across extended operating periods.
Large Diameter Voice Coil Technology
The B&C DE250TN utilizes a 44 mm (1.7 inch) aluminium voice coil optimized for thermal stability, efficiency, and professional reliability.
The large voice coil diameter allows the driver to comfortably manage 60 W nominal power handling and 120 W continuous power handling, supporting sustained high-output operation across professional applications.
Aluminium winding material reduces moving mass while maintaining efficient power transfer. This helps improve transient response and supports more accurate reproduction of musical detail and speech content.
The driver also incorporates extremely low inductance at 0.11 mH, helping maintain extended frequency response and smooth operation throughout the usable bandwidth.
Titanium Diaphragm Performance
The B&C DE250TN features a precision-engineered titanium diaphragm, selected for its rigidity, durability, and excellent high-frequency performance.
Titanium diaphragm construction provides improved mechanical strength and stability while maintaining the low moving mass required for accurate high-frequency reproduction. These properties allow the driver to deliver detailed musical information and articulate vocal reproduction even at elevated output levels.
The diaphragm assembly supports frequency reproduction up to 18 kHz, ensuring excellent reproduction of upper harmonics, vocal detail, and musical transients.
Its robust construction also contributes to long-term reliability in demanding professional sound reinforcement applications.
Extended Frequency Response and System Integration
With an operating range extending from 1 kHz to 18 kHz, the B&C DE250TN offers broad bandwidth coverage suitable for numerous loudspeaker applications.
The lower frequency capability allows improved flexibility when designing two-way systems while supporting seamless integration within multi-way loudspeaker platforms.
B&C recommends a crossover frequency of 1.5 kHz, enabling designers to maximize system performance while maintaining reliability and controlled diaphragm operation.
This broad operating range contributes to improved speech intelligibility, natural vocal reproduction, and smooth system integration.
