B&C DE914TN – Highest Flux Density 1.4-Inch Compression Driver with 75 mm Voice Coil and 110 Watt AES Power Handling
The B&C DE914TN sits at the very top of B&C’s professional 1.4-inch compression driver range, combining a massive 75 mm (3-inch) voice coil, 110 W AES power handling, 108 dB sensitivity, and an industry-leading 2.05 Tesla neodymium motor. Among B&C’s high-frequency compression drivers, the DE914TN is notable not simply because of its power rating, but because it achieves that rating while generating the highest magnetic flux density found in B&C’s 1.4-inch compression driver catalogue.
While models such as the DE800 and DE90TN also deliver 110 W AES power handling, the B&C DE914TN takes motor strength a step further. Its 2.05 T flux density exceeds the DE800’s 1.85 T and the DE90TN’s 1.8 T, giving the diaphragm greater electromagnetic control throughout its operating range. For system designers, that means improved efficiency, enhanced transient response, greater detail retrieval, and exceptional accuracy at high output levels.
The DE914TN combines this powerful motor structure with a pure titanium diaphragm, a material widely respected in professional touring audio for its stiffness, projection, and ability to maintain clarity at extreme sound pressure levels. The result is a compression driver capable of delivering outstanding vocal articulation, exceptional presence, and long-throw projection in large-scale sound reinforcement systems.
With a frequency response extending from 500 Hz to 18 kHz, a recommended crossover frequency of 1.2 kHz, and a compact 2.4 kg neodymium design, the B&C DE914TN is engineered for premium touring loudspeakers, large-format point source systems, stadium installations, arena sound reinforcement, and flagship line array designs where maximum performance is the priority.
The combination of 110 W AES power handling, 220 W continuous program power, 2.05 Tesla flux density, and a 75 mm voice coil places the B&C DE914TN among the most capable high-frequency compression drivers available for professional loudspeaker design.
Design and Construction of the B&C DE914TN
At the heart of the B&C DE914TN is a 75 mm aluminium voice coil, one of the largest voice coils used in B&C’s professional high-frequency compression driver range.
Voice coil diameter is one of the primary factors that determines a compression driver’s thermal capacity. Larger coils distribute heat across a greater surface area, allowing the assembly to withstand sustained power levels that would quickly overwhelm smaller designs.
This is the reason the DE914TN achieves:
- 110 W AES power handling
- 220 W continuous program power
- Extended thermal stability
- High output over prolonged operating periods
Compared with B&C’s 65 mm voice coil models such as the DE680TN, DE640U, DE640P, and DE610 family, the larger 75 mm coil provides significantly greater thermal capacity and long-term reliability under demanding operating conditions.
For touring systems operating at high SPL levels night after night, this additional thermal headroom becomes a significant advantage.
The voice coil uses aluminium winding material, selected for its excellent conductivity and low mass. Lower moving mass allows the diaphragm assembly to respond rapidly to transient information while maintaining the efficiency required for professional sound reinforcement applications.
The result is a driver capable of delivering substantial output without sacrificing clarity or dynamic accuracy.
The Most Powerful Motor in B&C’s 1.4-Inch Compression Driver Range
The defining feature of the B&C DE914TN is its remarkable 2.05 Tesla magnetic flux density.
This figure is not simply impressive on paper. It has direct implications for real-world performance.
The motor generates more magnetic force than virtually every other 1.4-inch compression driver in B&C’s range:
| Model | Flux Density |
|---|---|
| DE640P | 1.95 T |
| DE800 | 1.85 T |
| DE90TN | 1.80 T |
| DE82TN | 1.80 T |
| DE60TN | 1.60 T |
| DE914TN | 2.05 T |
The stronger magnetic field exerts greater control over the voice coil and diaphragm assembly.
This produces several important benefits:
- Improved transient response
- Better diaphragm control
- Increased efficiency
- Reduced distortion
- Superior dynamic accuracy
- Enhanced detail retrieval
When reproducing complex programme material at high output levels, stronger motor control helps maintain clarity and definition that weaker motors can struggle to preserve.
The 2.05 Tesla motor is therefore one of the primary reasons the DE914TN occupies a flagship position within B&C’s compression driver portfolio.
Pure Titanium Diaphragm Technology
The B&C DE914TN uses a pure titanium diaphragm, a material that has become a benchmark choice for professional touring and concert sound systems.
Titanium offers several important advantages.
Its high stiffness allows the diaphragm to maintain pistonic behaviour over a wide operating bandwidth. This helps preserve detail and accuracy while minimizing unwanted flexing and breakup modes.
Titanium is also extremely durable under the mechanical stresses encountered in professional sound reinforcement applications.
Compared with polymer diaphragms, titanium generally delivers:
- Greater projection
- Increased presence
- Enhanced vocal intelligibility
- Stronger upper-midrange energy
- Superior long-distance coverage
This makes titanium particularly popular in touring systems where sound must maintain impact and intelligibility across large audiences.
Compared with the composite Polyimide/Titanium diaphragm used in the DE800, the DE914TN’s pure titanium diaphragm delivers a more direct and energetic presentation, making it particularly effective in high-output environments where maximum projection is required.
The titanium diaphragm is one of the key reasons the B&C DE914TN excels in large-format professional audio systems.
Exceptional Power Handling Performance
The B&C DE914TN is rated at:
- 110 W AES power handling

For professionals who require dependable high-output performance, this thermal capability is a major advantage.
Frequency Response and Low-Frequency Extension
The B&C DE914TN offers a frequency response spanning 500 Hz to 18 kHz.
This unusually low extension for a compression driver provides system designers with additional flexibility when integrating the driver into multi-way loudspeaker systems.
Lower operating capability allows:
- Improved crossover flexibility
- Better integration with midrange devices
- Reduced crossover complexity
- More consistent directivity through the crossover region
The recommended crossover frequency of 1.2 kHz ensures reliable operation while taking advantage of the driver’s substantial motor and diaphragm assembly.
For large-format two-way systems, this capability can simplify system architecture while maintaining excellent performance.
Efficiency and Acoustic Output
The 108 dB sensitivity rating of the DE914TN places it among the most efficient compression drivers in its class.
High sensitivity means more acoustic output is produced from every watt of amplifier power.
This provides several advantages:
