        Product details Radian 12CRF6430

        Radian 12CRF6430 12” coaxial with planar ribbon HF

         

        Designed to provide ultimate sound quality, the Radian 12CRF6430 stands out for its highly coherent coaxial configuration and planar ribbon high-frequency driver. The HF section uses a robust Kapton diaphragm with a neodymium magnet, offering an impressive frequency range up to 30 kHz and a sensitivity of 103.5 dB. The low-frequency driver features a 305 mm paper/Kevlar composite cone and a 64 mm copper-clad aluminum voice coil, supporting continuous program power of 600 W. Together, these elements create a versatile transducer perfect for audiophile-grade speakers and professional monitoring systems.

         

        The Radian 12CRF6430 is engineered for low distortion and high fidelity. Dual aluminum demodulation rings in the LF/MF section reduce distortion, while completely separate LF and HF magnetic systems eliminate flux modulation and unwanted intermodulation effects. The 100° conical coverage pattern ensures even sound distribution throughout the listening area, with precise pattern control down to 800 Hz. This makes it suitable for both studio and high-end home audio applications, as well as demanding commercial sound reinforcement.

         

        This coaxial driver is built for reliability and performance, with high-temperature polyimide voice coil formers and a rugged cast aluminum octagonal frame. The recommended enclosure volume ranges from 35 to 70 liters, allowing for flexible integration in custom or OEM designs. Optional accessories include a premium assembled crossover, making it easy to pair with advanced assembled crossovers for seamless integration in sophisticated audio systems.

         

        With a balanced response, extended low-frequency performance, and the precision of planar ribbon technology, the Radian 12CRF6430 excels in systems requiring both accuracy and musicality. Its robust 600 W continuous program power handling, combined with low distortion and wide coverage, makes it a top choice for high-end audio installations and DIY speaker kit projects where exceptional sound is the priority. For those seeking an advanced solution in audio components, this driver offers a blend of innovation, durability, and superior sonic performance.
