B&C DE64TN – High-Power 2-Inch Titanium Compression Driver for Professional Sound Reinforcement
The B&C DE64TN is a high-performance 2-inch compression driver engineered for professional loudspeaker systems that demand exceptional output, reliable power handling, and outstanding vocal clarity. Designed around a robust 75 mm (3-inch) aluminium voice coil, a powerful 1.6 Tesla neodymium motor structure, and a precision titanium diaphragm, the B&C DE64TN delivers the performance required for touring systems, stadium installations, high-output point source loudspeakers, and premium fixed-installation sound reinforcement.
Within the professional audio industry, 2-inch compression drivers occupy a unique position. They are often chosen for applications where high acoustic output, lower crossover frequencies, and superior midrange projection are essential. The B&C DE64TN has been developed specifically to excel in these demanding environments, offering an impressive 110 W AES power handling rating, 220 W continuous program power capacity, and a broad operating range extending from 1 kHz to 18 kHz.
With a sensitivity rating of 107.5 dB, the driver provides exceptional efficiency, allowing system designers to achieve substantial sound pressure levels while minimising amplifier requirements. This high efficiency contributes to improved system headroom, greater dynamic performance, and reduced thermal stress throughout the signal chain.
The B&C DE64TN combines the authority and projection traditionally associated with large-format compression drivers with the detail and articulation required for modern professional sound reinforcement. Its ability to reproduce vocals, speech, and high-frequency programme material with accuracy and consistency makes it an excellent choice for loudspeaker manufacturers, system integrators, and professional audio engineers seeking a premium 2-inch compression driver solution.
Whether deployed in a large-format touring enclosure, a stadium PA system, a theatre installation, or a high-performance club sound system, the B&C DE64TN delivers the reliability and sonic performance expected from a professional-grade B&C transducer.
Purpose-Built 2-Inch Compression Driver Design
The B&C DE64TN has been engineered to maximise the advantages offered by a 2-inch throat format.
Compared with smaller throat compression drivers, a 2-inch design offers several benefits:
- Improved low-frequency loading
- Enhanced midrange authority
- Greater acoustic output capability
- Increased system efficiency
- Lower crossover flexibility
- Superior vocal projection
These characteristics make large-format compression drivers particularly effective in professional sound reinforcement systems where long-throw performance and high output are required.
The DE64TN takes full advantage of these benefits, delivering a sound character that combines powerful midrange reproduction with smooth high-frequency extension.
For system designers, this results in improved flexibility when creating loudspeaker systems intended for demanding applications.
Powerful 75 mm Voice Coil Architecture
At the centre of the B&C DE64TN is a substantial 75 mm (3-inch) aluminium voice coil.
The voice coil plays a critical role in determining both power handling capability and long-term reliability.
A larger voice coil offers significant advantages:
- Greater thermal capacity
- Improved heat dissipation
- Higher continuous output capability
- Reduced thermal compression
- Increased operational consistency
- Enhanced durability
The DE64TN is rated for:
- 110 W nominal power handling
- 220 W continuous program power handling
allowing it to maintain exceptional performance even under sustained high-output operating conditions.
In demanding professional environments where loudspeaker systems may be required to operate continuously for extended periods, thermal stability becomes essential.
The large voice coil helps ensure consistent performance throughout long events while reducing the risk of performance degradation caused by excessive heat build-up.
High-Energy Neodymium Motor System
The B&C DE64TN incorporates a powerful neodymium motor structure generating 1.6 Tesla of magnetic flux density.
The motor system is responsible for controlling diaphragm movement and converting electrical energy into acoustic output with maximum efficiency.
The benefits of the high-energy motor include:
- Increased sensitivity
- Improved transient response
- Better diaphragm control
- Reduced distortion
- Higher output capability
- Enhanced dynamic performance
The strong magnetic field ensures accurate diaphragm movement even during demanding programme material and high sound pressure level operation.
This contributes directly to the driver’s impressive sensitivity rating and overall sonic performance.
Neodymium technology also enables a more compact and lightweight design than comparable ferrite-based alternatives.
Despite its substantial output capability, the DE64TN remains relatively manageable in terms of weight and installation requirements.
Titanium Diaphragm Technology
A defining feature of the B&C DE64TN is its precision-engineered titanium diaphragm.
Titanium remains one of the most widely respected diaphragm materials in professional audio due to its excellent combination of rigidity, durability, and low mass.
The benefits of titanium include:
- Excellent stiffness-to-weight ratio
- Outstanding transient response
- High power handling capability
- Superior long-term durability
- Exceptional projection characteristics
- Consistent performance at elevated SPL levels
These characteristics allow the DE64TN to reproduce complex programme material with remarkable accuracy while maintaining the output levels required in professional sound reinforcement environments.
Titanium diaphragms are particularly valued in touring and installed sound applications where systems must deliver consistent performance under challenging operating conditions.
The DE64TN uses these properties to provide strong vocal articulation, excellent speech intelligibility, and impressive high-frequency detail.
Exceptional Efficiency and Acoustic Output
The B&C DE64TN achieves a sensitivity rating of 107.5 dB.
This level of efficiency provides significant advantages for professional loudspeaker systems.
Benefits include:
Greater Output per Watt
More acoustic energy is produced from every watt of amplifier power.
Improved System Headroom
Higher efficiency allows systems to operate with increased dynamic range.
Reduced Amplifier Demand
Less amplifier power is required to achieve target sound pressure levels.
Enhanced Reliability
Lower amplifier stress can contribute to improved overall system longevity.
Better Dynamic Performance
Highly efficient drivers respond quickly and accurately to transient programme material.
For large-scale sound reinforcement applications, these benefits can significantly improve overall system performance.
Wide Frequency Response and Crossover Flexibility
The B&C DE64TN offers a frequency response spanning:
1 kHz – 18 kHz
This broad operating range allows the driver to reproduce critical vocal information, speech content, and high-frequency detail with exceptional consistency.
The driver features a recommended crossover frequency of:
1 kHz
This relatively low crossover capability provides several benefits:
- Better integration with low-frequency drivers
- Improved vocal coherence
- Enhanced directivity control
- Reduced crossover complexity
- Greater design flexibility
For professional loudspeaker manufacturers, the ability to cross over at 1 kHz can significantly improve system performance throughout the critical vocal region.
This makes the DE64TN particularly effective in applications where speech intelligibility and vocal projection are priorities.
Low Inductance for Enhanced High-Frequency Accuracy
The B&C DE64TN features an inductance rating of only 0.14 mH.
Low inductance contributes to:
- Improved transient response
- Better high-frequency extension
- More predictable crossover behaviour
- Increased clarity
- Reduced phase irregularities
These characteristics help maintain smooth and accurate performance throughout the driver’s operating range.
For system designers working with advanced DSP processing and sophisticated crossover networks, low inductance can simplify integration and improve overall system predictability.
