Features


  • 15" coaxial loudspeaker with 400Wrms (AES standard) power handling and 97dB sensitivity
  • Full range frequency response: 40 – 20,000Hz
  • FEA (Finite Element Analysis) optimized ferrite magnet assembly acts as common motor for both LF and HF drivers resulting in enhanced coherence
  • Robust cast aluminium chassis is designed to minimize unwanted reflections,
    further reducing acoustic distortion
  • Demodulation ring reduces flux modulation, minimizing electromagnetic distortion
  • 3" edgewound copper clad aluminium voice coil wound on high temperature glass fibre former
  • 90° nominal HF coverage

Frequency Response and Impedance Curves

Product Graph
  1. Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power calculated on minimum impedance. Loudspeaker tested in free air.
  2. Continuous Power Handling is defined as 3dB greater than the AES rating.
  3. Measured on axis at 1W, 1m in 2π anechoic environment.
  4. Xmax derived from: (voice coil winding width-gap depth)/2.
  5. 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.
  6. Continuous Power Handling is defined as 3dB greater than the AES rating.
