CDF1.17BPM8 - 1 Inch HF Driver

High-Output High-Frequency Driver for Professional Sound Reinforcement

The CDF1.17BPM8 is a high-output 1" exit compression driver engineered for professional sound reinforcement systems requiring maximum sensitivity, extended high-frequency output, and stable performance under continuous operation. Designed by B&C Group and manufactured to Eminence Pro™ standards, this driver is optimized for OEM loudspeaker platforms in portable PA, stage monitor, and fixed installation applications where elevated SPL capability is a priority.

Rated at 60 W nominal / 120 W continuous program power, the CDF1.17BPM8 delivers exceptionally high acoustic output with minimal amplifier demand. With a 108.5 dB sensitivity, it is the highest-sensitivity model in this series, enabling efficient system designs and increased headroom in high-output two-way configurations. The driver operates over a 1.0 kHz – 18 kHz frequency range and is optimized for use with a 1.2 kHz or higher crossover slope (12 dB/oct or greater).

The motor assembly incorporates a 44 mm (1.7") aluminum voice coil combined with a polyimide diaphragm, providing enhanced thermal stability, durability, and power handling compared to polyester-based diaphragm designs. A 1" (25 mm) throat exit ensures compatibility with a wide range of professional HF horns and waveguides, including high-directivity designs used in demanding SPL applications.

Multiple standardized mounting patterns and a compact, robust motor structure support straightforward integration into scalable OEM production environments while maintaining consistent, repeatable performance.
