B&C DCX462 2-Inch Coaxial Midrange & High Frequency Compression Driver – 8 Ohm
Professional Coaxial Compression Driver for High-Output Point Source Systems
The B&C DCX462 is a premium dual-diaphragm coaxial compression driver engineered to deliver exceptional vocal clarity, high sensitivity, and wide bandwidth performance in professional loudspeaker systems. Designed around B&C Speakers’ advanced coaxial compression driver technology, the B&C DCX462 combines a powerful midrange section and high-frequency section within a single compact assembly, providing seamless acoustic integration and outstanding phase coherence.
Built for demanding touring, installation, and high-performance sound reinforcement applications, the B&C DCX462 offers a highly efficient solution for designers seeking point-source accuracy with reduced crossover complexity. By integrating both the mid-frequency and high-frequency drivers into one unit, the DCX462 enables superior directivity control, improved acoustic alignment, and a more compact loudspeaker design.
The driver features a 2-inch throat diameter, allowing integration with a wide range of professional horns and waveguides. Its dual-ring diaphragm architecture combines a dedicated midrange compression driver and high-frequency compression driver within a single motor structure, creating an exceptionally coherent acoustic source capable of covering frequencies from 300 Hz to 18 kHz.
For loudspeaker manufacturers and system designers looking to achieve premium performance while minimizing acoustic interference between separate drivers, the B&C DCX462 represents one of the most advanced coaxial compression driver solutions available.
Advanced Dual-Diaphragm Coaxial Design
At the heart of the B&C DCX462 is a sophisticated coaxial architecture that combines independent midrange and high-frequency compression driver sections into a single compact device.
The mid-frequency section utilizes a substantial 100 mm (4-inch) aluminium voice coil coupled to an HT Polymer Ring diaphragm. This large-format assembly delivers impressive output and low-frequency extension, enabling operation down to 300 Hz while maintaining excellent efficiency and low distortion.
Mounted concentrically within the same acoustic structure is the high-frequency section, featuring a 65 mm (2.5-inch) aluminium voice coil paired with its own HT Polymer Ring diaphragm. This dedicated HF system covers frequencies from 3.5 kHz to 18 kHz, delivering smooth detail, extended response, and exceptional vocal articulation.
Because both sections share the same acoustic axis, the B&C DCX462 produces significantly improved phase coherence compared to traditional multi-driver horn systems. The result is more accurate imaging, smoother crossover integration, and consistent coverage throughout the listening area.
Outstanding Sensitivity and Dynamic Output
One of the defining characteristics of the B&C DCX462 is its exceptional sensitivity.
The midrange section achieves an impressive 111.1 dB sensitivity, while the high-frequency section reaches 111.4 dB sensitivity, allowing the driver to generate substantial acoustic output with minimal amplifier power.
This high efficiency makes the B&C DCX462 particularly suitable for professional systems where maximum SPL, reduced amplifier demand, and improved thermal performance are critical requirements.
With 110 Watts nominal power handling and 220 Watts continuous power handling in the midrange section, alongside 80 Watts nominal and 160 Watts continuous power handling in the HF section, the driver maintains reliable operation even under sustained high-output conditions.
This combination of power handling and efficiency makes the DCX462 ideal for:
- Touring sound systems
- High-output point source loudspeakers
- Stadium and arena installations
- Concert reinforcement systems
- Houses of worship
- Theatre sound systems
- Professional monitoring applications
- Premium fixed installations
Wide Frequency Coverage for Reduced System Complexity
The B&C DCX462 offers broad frequency coverage that simplifies loudspeaker design while maintaining excellent sonic performance.
The midrange section operates from 300 Hz to 5.5 kHz, providing exceptional vocal reproduction, instrument definition, and critical mid-band accuracy. This wide operating range allows system designers to reduce crossover complexity while maintaining smooth acoustic performance.
The high-frequency section extends coverage from 3.5 kHz to 18 kHz, delivering detailed high-frequency reproduction with excellent transient response and clarity.
Recommended crossover points include:
- Midrange Section: 300 Hz
- High-Frequency Section: 4 kHz
These crossover frequencies allow the driver to integrate effectively within advanced multi-way loudspeaker systems while preserving its exceptional coherence and output capabilities.
HT Polymer Ring Diaphragm Technology
Both the midrange and high-frequency sections utilize advanced HT Polymer Ring diaphragms, a technology that offers several advantages over traditional metallic diaphragms.
HT Polymer Ring diaphragms provide:
- Improved damping characteristics
- Reduced resonance behaviour
- Lower distortion levels
- Smooth frequency response
- Enhanced reliability
- Improved fatigue resistance
- Consistent performance at high output levels
The result is a natural and highly intelligible sound character that performs exceptionally well in both speech reinforcement and music reproduction applications.
This diaphragm technology contributes significantly to the DCX462’s reputation for delivering smooth, controlled, and accurate audio reproduction across its operating bandwidth.
Powerful Neodymium Motor Structure
The B&C DCX462 incorporates advanced neodymium motor technology to maximize efficiency while minimizing overall weight.
The midrange motor generates an impressive 1.9 Tesla flux density, while the high-frequency section achieves an even stronger 2.14 Tesla flux density.
These powerful magnetic fields improve:
- Driver efficiency
- Voice coil control
- Transient response
- Dynamic accuracy
- Thermal stability
- Overall sensitivity
The use of neodymium technology allows the driver to deliver outstanding performance while maintaining a relatively manageable weight of only 3.26 kg (7.19 lb).
For touring professionals and system manufacturers, this weight reduction contributes to lighter loudspeaker designs without sacrificing performance.
Compact Installation-Friendly Design
Despite its powerful output capabilities, the B&C DCX462 remains remarkably compact and easy to integrate into professional loudspeaker systems.
Key mounting dimensions include:
- Overall Diameter: 152 mm (5.98 in)
- Depth: 110 mm (4.33 in)
- Mounting Pattern: Four M6 holes on a 102 mm (4-inch) diameter
- Net Weight: 3.26 kg (7.19 lb)
These dimensions make the driver suitable for a wide range of horn and waveguide configurations while simplifying cabinet design and installation.
Its compact footprint allows designers to create highly efficient loudspeaker systems without compromising acoustic performance or coverage characteristics.
