Features

  • 8" coaxial loudspeaker providing 200Wrms (AES standard) power handling and 94dB sensitivity
  • Full range frequency response: 70 – 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
  • 2" edgewound copper voice coil wound on high temperature glass fibre former
  • 100° nominal HF coverage

8Ω Frequency Response

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. Measured on axis at 1W, 1m in 2π anechoic environment.
  3. Xmax derived from: (voice coil winding width-gap depth)/2.
