Compact Professional Compression Driver Design
The B&C DH350H has been engineered to deliver professional acoustic performance from an exceptionally compact platform. Featuring a 25 mm (1 inch) throat diameter, the driver integrates easily with professional horns and waveguides while maintaining a minimal installation footprint.
Its reduced physical dimensions make the driver particularly suitable for compact loudspeaker systems where space limitations and weight reduction are important considerations.
Despite its compact size, the driver produces 108 dB sensitivity, providing excellent acoustic output capability with efficient amplifier utilization. This high efficiency makes it ideal for professional applications where maximizing output from smaller systems is essential.
The compression driver architecture promotes efficient acoustic coupling between the diaphragm and horn structure, supporting improved directivity control and acoustic performance.
High-Energy Magnetic Circuit Technology
The B&C DH350H incorporates a high-performance magnetic structure engineered to maximize sensitivity and diaphragm control.
The motor assembly generates 1.8 Tesla magnetic flux density, creating strong magnetic force for precise control of diaphragm movement and improved transient performance.
The powerful magnetic circuit contributes directly to the driver’s high sensitivity rating while helping reduce distortion during high-output operation.
Strong diaphragm control is particularly important in compact compression drivers, where maintaining accuracy under demanding operating conditions is critical.
Combined with the lightweight moving assembly, the magnetic system supports excellent clarity and reliable long-term performance.
HT Polymer Diaphragm Technology
The B&C DH350H utilizes an advanced HT Polymer diaphragm engineered for smooth response characteristics and dependable operation.
HT Polymer materials provide an effective balance between low moving mass, mechanical stability, and thermal reliability. These properties help maintain consistent acoustic performance during prolonged professional use.
The diaphragm contributes to accurate vocal reproduction, improved speech intelligibility, and smooth musical detail across the driver’s operating range.
Its lightweight construction enables fast transient response while helping maintain controlled diaphragm behaviour at higher output levels.
The diaphragm design also contributes to the driver’s reliability in portable and installed sound applications.
Large Diameter Voice Coil Design
At the core of the B&C DH350H is a 36 mm (1.4 inch) aluminium voice coil, engineered for efficient thermal management and professional reliability.
The voice coil supports 30 W nominal power handling and 60 W continuous power handling, enabling the driver to operate effectively across numerous professional applications.
Aluminium winding material helps reduce moving mass while preserving efficiency, supporting faster transient response and improved detail retrieval.
The driver also incorporates extremely low inductance at 0.09 mH, helping preserve extended high-frequency performance and smooth response characteristics.
This combination of efficient materials and optimized motor design contributes significantly to the driver’s professional acoustic performance.
Extended Bandwidth Performance
The B&C DH350H provides an operating bandwidth extending from 1 kHz to 17 kHz, supporting broad high-frequency coverage for professional sound reinforcement applications.
Its lower frequency capability provides additional flexibility when designing compact two-way systems or integrating the driver within larger multi-way loudspeaker configurations.
B&C recommends a crossover frequency of 1 kHz, enabling greater design flexibility while maintaining reliable operation.
The broad operating range contributes to natural vocal reproduction, strong speech intelligibility, and detailed musical performance.
Professional System Integration
The compact design and lightweight construction of the B&C DH350H make it highly versatile across numerous professional loudspeaker applications.
Typical applications include:
- Compact two-way loudspeakers
- Portable PA systems
- Column loudspeaker systems
- Stage monitors
- Installed sound systems
