Radian manufactures replacement diaphragms that fit popular compression drivers found in home and professional loudspeaker systems. Each diaphragm employs aluminum alloy dome/Mylar® surround construction to provide high efficiency, accurate reproduction, and extended bandwidth. Radian's use of sophisticated materials and processes results in diaphragms that have equivalent or better performance than the original. Made in the USA. Fits 8 ohm JBL 375H, 376, 2440, 2441, 2445, 2446, 2450, 2451.
Radian manufactures premium replacement diaphragms that fit popular compression drivers used in professional loudspeaker systems. Each aluminum alloy replacement diaphragm provides high efficiency and accurate reproduction with extended bandwidth. Replacement diaphragms are designed and manufactured to have equivalent or better performance than the original.
Compression domes are precision formed from heat-treated, structural aluminum alloy and bonded to a copper-clad aluminum voice coil with a Kapton® former utilizing proprietary tooling. Aluminum has a higher strength-to-weight ratio than titanium providing low-distortion, high-fidelity response that delivers clear, crisp music and speech for theatrical, auditorium, stadium and church installations.
The suspension is made of specially developed Mylar®. Utilizing a Mylar® surround enhances the replacement diaphragm’s reliability and eliminates fatigue stresses that destroy other compression driver diaphragms. The Mylar® surround also provides good dampening of the voice coil/diaphragm assembly for smooth, low-distortion, linear output with excellent transient response. To ensure longer diaphragm life, our high temperature voice coil former and advanced adhesives permit each replacement diaphragm to sustain high RMS and peak power levels, equivalent or better than the original.
The diaphragm/voice coil assembly may be rapidly readily replaced in the field. The self-aligning diaphragm assembly assures simple installation and accurate alignment with same polarity as the original.
Unparalleled power handling, high-frequency performance, reliability and low-distortion make Radian premium replacement diaphragms the preferred choice for loudspeaker repair centers, consultants, sound system designers, contractors and engineers worldwide.
