CDF1.17APM8 - 1 Inch HF Driver

High-Sensitivity High-Frequency Driver for Professional Sound Reinforcement

The CDF1.17APM8 is a high-output 1" exit compression driver engineered for professional sound reinforcement systems requiring extended high-frequency response, elevated sensitivity, and reliable 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.

Rated at 60 W nominal / 120 W continuous program power, the CDF1.17APM8 supports high acoustic output with minimal amplifier demand. Its 107.5 dB sensitivity enables efficient system designs where maximum SPL and clarity are required. The driver operates over an extended 0.8 kHz – 18 kHz frequency range and is optimized for use with a 1.2 kHz or higher crossover slope (12 dB/oct or greater), allowing for flexible integration in two-way system designs.

The motor assembly incorporates a 44 mm (1.7") aluminum voice coil paired with a polyimide diaphragm, providing improved thermal stability and durability compared to polyester-based designs. A 1" (25 mm) throat exit ensures compatibility with a wide range of professional HF horns and waveguides, including compact and high-directivity designs.

With standardized mounting geometry and compact form factor, the CDF1.17APM8 integrates easily into scalable OEM production environments, delivering consistent, repeatable high-frequency performance across production runs.
