B&C DH450-8 1 Inch HF Driver For Professional PA Speakers With 40W Continuous Power
Posted by https://vipproaudio.com/ on Aug 13th 2026
If you are building a professional PA system where clear, detailed high frequencies and reliable performance matter, the B&C DH450-8 1-inch HF Driver is a compact solution designed to deliver impressive results without adding unnecessary size or weight. Part of B&C’s innovative HLX™ Series, the DH450 uses a helical phase plug approach to achieve the efficiency and performance of a larger compression driver in a remarkably compact design.
The B&C DH450-8 combines a 1-inch throat, 44 mm aluminium voice coil, and HT Polymer diaphragm to provide a 1000–18000 Hz frequency response with 109 dB sensitivity. Its 40 W continuous power handling makes it well suited for professional PA speaker applications where dependable high-frequency reproduction and efficient performance are essential.
The HLX™ design is at the heart of the DH450’s performance. Its patented phase plug uses a central channel twisted in a helical pattern to match the length of the outer channels. This innovative approach helps create a compact driver while supporting efficient magnetic flux use, reduced distortion, and a low crossover point of around 1 kHz. The result is a practical high-frequency driver that can help professional speaker designers achieve detailed and efficient HF output in a compact format.
Features:
- Innovative HLX™ Series Design:
The DH450 uses B&C’s HLX™ helical phase plug technology to achieve compression-driver efficiency in a compact package. The design helps minimize the driver’s diameter, weight, and overall size while maintaining strong performance.
- 1-Inch Horn Throat:
With a 25 mm (1-inch) throat diameter, the DH450 is designed for use with compatible 1-inch horn and waveguide systems in professional PA applications.
- 44 mm Aluminium Voice Coil:
The 44 mm (1.7-inch) aluminium voice coil provides the driver with a compact and efficient motor structure while supporting its 40 W continuous power handling.
- HT Polymer Diaphragm:
The HT Polymer diaphragm is engineered for high-frequency reproduction, helping the driver deliver a wide 1000–18000 Hz response for detailed HF performance.
- 109 dB Sensitivity:
With 109 dB sensitivity, the DH450 is designed to produce strong acoustic output efficiently, making it a practical choice for professional PA speaker systems.
- 40 W Continuous Power Handling:
The 40 W continuous power capacity provides dependable performance for demanding professional audio applications when the driver is properly matched and operated within its specifications.
- Very Compact 69 mm Diameter:
The DH450’s compact 69 mm diameter makes it an attractive option for speaker designs where space, weight, and efficiency are important considerations.
- Designed for Efficient HF Performance:
The HLX™ approach helps make more efficient use of magnetic flux while supporting reduced distortion, including intermodulation distortion, for cleaner high-frequency reproduction.
- Low Crossover Capability:
With a response beginning around 1000 Hz, the DH450 is designed to support a low crossover point, giving speaker designers greater flexibility when developing professional PA systems.
