PRODUCT INFO Radian Audio Engineering, Inc., manufactures premium replacement diaphragms for TAD 2" throat exit compression drivers. The Radian Model 1292-8 replacement diaphragm allows the usable frequency response of TAD compression drivers to a full-range response of 600 Hz to 20 kHz. By replacing the original diaphragm, an old magnet structure can be used to rival the performance of a current TAD compression driver. Each replacement diaphragm provides high efficiency and accurate reproduction with extended bandwidth. 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 high strengthto- weight ratio providing low-distortion, highfidelity response that delivers clear, crisp music and speech for theatrical, auditorium, stadium and church installations. The suspension utilizes a Mylar surround, rather than a metal one-piece dome and surround, which 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. If necessary, the diaphragm/voice coil assembly may be rapidly replaced in the field. The selfaligning diaphragm assembly assures simple installation and accurate alignment with the same polarity as the original. As with all Radian Premium Replacement Diaphragms, the 1292 is also Ferro-Fluid compatible enabling even greater output and power handling. Unparalleled power handling, highfrequency 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.
