The Radian 475PB-8 is a professional 1-inch exit high-frequency driver, engineered to deliver transparent, high-resolution sound in demanding audio environments. This robust compression driver is designed for long-term, high-stress operation, making it ideal for touring sound, stage monitors, and high-performance installed and portable sound systems. With its advanced materials and precision engineering, the 475PB-8 ensures extended frequency response, impressive power handling, and reliable performance for a wide range of audio applications.
Radian 475PB-8 1” exit HF driver
The Radian 475PB-8 stands out with its proprietary aerospace-grade aluminum alloy diaphragm, offering the highest tensile strength-to-weight ratio for long-term fatigue resistance and accurate signal peak reproduction. This advanced diaphragm design, paired with a high-damping structure, eliminates the ringing common in other metal domes, resulting in a remarkably transparent and detailed sound signature. The heat-stabilized polymer surround ensures low distortion even at high sound pressure levels, supporting consistent long-term performance.
With a frequency range extending from 1 kHz to 25 kHz and a sensitivity of 109.5 dB, the 475PB-8 is perfectly suited for high-fidelity tweeters in professional speakers and sound reinforcement systems. Its robust 44.5 mm edge-wound ribbon wire voice coil, built with advanced adhesives, guarantees maximum reliability and durability under continuous operation. The copper demodulation ring inside the magnetic gap further enhances linearity and reduces distortion, ensuring clean and precise high-frequency reproduction.
The driver is designed for effortless integration into a variety of sound system configurations, thanks to its self-aligning diaphragm assembly and versatile mounting options. Its 1-inch (25.4 mm) nominal exit diameter and 11.4° exit angle make it compatible with most standard horns and waveguides, allowing for optimal dispersion and coupling in professional audio setups. Whether used in touring rigs, stage monitors, or high-performance installed systems, the 475PB-8 excels in delivering articulate and powerful high-frequency output.
For users seeking easy maintenance, the 475PB-8 offers an optional replacement diaphragm assembly, and its binding post connections simplify setup within custom enclosures or as part of audio components kits. The durable ferrite magnet and polyimide voice coil former further contribute to the driver’s long service life, making it a reliable choice for demanding audio professionals and enthusiasts alike.
