The JBL RPD3300Ti-16 is a professional-grade replacement diaphragm assembly for JBL 3-inch voice coil high-frequency compression drivers, specifically designed to restore or upgrade the performance of large-format cinema and professional sound reinforcement systems. This critical component features a precision-engineered selenium-doped titanium diaphragm, a material choice renowned for its exceptional rigidity, low mass, and controlled break-up characteristics, which together yield extended high-frequency response with minimal distortion. The 16-ohm impedance version allows for direct compatibility with a specific range of JBL compression drivers, ensuring proper electrical and acoustic integration to maintain the driver's intended sonic signature and power handling capabilities.

The assembly is manufactured to exacting mechanical tolerances, guaranteeing a perfect fit within the motor structure of compatible drivers such as those in the JBL 2450 and similar series. The design incorporates a robust edge suspension that supports the linear excursion of the diaphragm while effectively damping undesirable resonances. The selenium doping process applied to the titanium enhances the material's internal damping, which further reduces high-frequency ringing and delivers smoother, more natural sound reproduction, particularly crucial for the demanding transient detail and dynamic range of cinema soundtracks and high-fidelity music reinforcement.

Intended for use by professional audio technicians and service centers, the RPD3300Ti-16 diaphragm is a genuine OEM part that ensures the restored driver performs to its original factory specifications. Its installation breathes new life into vital high-frequency components within cinema arrays, touring loudspeakers, and fixed installation systems, restoring critical clarity, headroom, and reliability. This component represents the commitment to serviceability and longevity in professional audio, allowing valuable transducers to be maintained at peak performance for extended periods rather than being replaced entirely.
