  • 2" exit, ferrite magnet, 3" voice coil compression driver provides 75Wrms (AES standard) power handling and 107dB sensitivity
  • Patented phase plug design method suppresses cavity resonances at higher frequencies
  • Titanium diaphragm, deep drawn to increase stiffness and reduce distortion
  • Lower compression ratio reduces air non-linearity and allows for higher maximum SPL
  • Rolled polyimide surround improves stiffness control, further lowering distortion
  • Curved coherent wavefront, optimised for horn loading

8Ω Frequency Response and Impedance Curves

Product Graph
  1. Tested for two hours on plane wave tube using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance.
  2. Continuous Power Handling is defined as 3dB greater than the AES rating.
  3. Measured on axis at 1W, 1m, using typical horn, in 2π anechoic environment.
