  • The High-Frequency Replacement Diaphragm is a premium, factory-grade audio repair component engineered to restore pristine treble clarity and high-SPL performance to professional compression drivers.
  • Designed as an exact-fit voice coil and dome assembly, this precision-calibrated replacement part is meticulously tailored for sound reinforcement technicians, rental audio crews, and venue engineers who need a direct drop-in solution to service and revive damaged high-frequency drivers.
  • Operating at a standard 8-Ohm nominal impedance, the diaphragm is engineered to handle intense electrical current from high-power passive crossovers without sacrificing transient response.
  • The assembly features a high-grade dome structure coupled with a precision-wound voice coil designed for optimal thermal dissipation and high acoustic power tracking.
  • Fabricated with integrated terminal contact points and an exact-alignment outer chassis frame, this replacement diaphragm provides a seamless fit and immediate restoration of crisp vocal intelligibility and high-frequency sparkle under demanding, live venue conditions.
Features
  • Targeted System Compatibility Drop-In: Engineered specifically to match the physical tolerances and acoustic parameters of the companion 15-inch dual speaker enclosures.
  • This exact factory calibration is perfectly optimized for immediate field replacement.
  • High-Conductivity Precision Voice Coil: Wound with high-temperature wire on a resilient former substrate.
  • This robust thermal layout is ideal for managing sudden signal spikes and sustained high-frequency drive levels without suffering electrical burnout.
  • Optimized High-Frequency Dome Geometry: Fabricated from an acoustically responsive, lightweight material matrix.
  • This strategic physical profile is critical for maintaining linear frequency response, low harmonic distortion, and crisp transient punch.
  • Seamless Alignment Chassis Frame: Built with precision-stamped outer positioning holes.
  • This drop-in structural envelope is essential for ensuring perfect centering of the voice coil inside the driver's narrow magnetic gap during installation.
  • Reliable 8-Ohm Impedance Integration: Configured with a standardized nominal impedance profile. This electrical matrix is perfect for maintaining original factory crossover points, phase relationships, and amplifier load matching.
