Radian 1225-8 Replacement diaphragm
The construction of the Radian 1225-8 Replacement Diaphragm centers on the use of a structural aluminum alloy, which provides a highly resilient yet lightweight diaphragm optimized for precise high-frequency reproduction. The diaphragm's unique processing ensures a superior tensile strength-to-weight ratio, resulting in outstanding fatigue resistance and minimal performance degradation over time. Paired with a polymer surround, the 1225-8 is engineered for low distortion, even at high sound pressure levels, making it a reliable choice for demanding audio environments.
Equipped with a 44.5 mm edge-wound ribbon wire voice coil made from copper-clad aluminum, the Radian 1225-8 offers enhanced efficiency and superior signal handling. The voice coil is supported by a high-temperature polyimide former and advanced adhesives, which maximize reliability during prolonged operation. This robust construction allows the diaphragm to handle up to 100 W of continuous program power, while maintaining a sensitivity of 108 dB, ensuring it meets the needs of both professional sound reinforcement and high-fidelity speakers.
Designed for versatility, the Radian 1225-8 Replacement Diaphragm covers a frequency range from 1.0 kHz to 25 kHz, making it suitable for use in a wide variety of tweeters and compression driver systems. The self-aligning diaphragm assembly simplifies field service and replacement, reducing downtime and ensuring consistent performance. Its compact dimensions and lightweight build make integration into existing systems straightforward, whether for professional PA applications or custom DIY speaker kits.
Whether you are maintaining legacy audio equipment or seeking to enhance the sonic performance of your current setup, the Radian 1225-8 delivers natural, transparent sound with extended high-frequency response. The diaphragm's wide compatibility and robust mechanical design make it a preferred choice among audio professionals and enthusiasts looking for reliable audio components that stand up to rigorous use.
