  • 600W continuous power handling and 97dB sensitivity
  • Tough 12" ferrite bass/mid loudspeaker with Kevlar loaded cone
  • Optimised magnet assembly delivers impressive power to weight ratio
  • 3" high temperature edgewound copper clad aluminium voice coil wound on glass fibre former for enhanced reliability
  • Double roll surround provides exceptional linearity at extremes of cone excursion
  • Robust steel chassis for maximum energy transfer
  • Ideal drop in replacement for Mackie SRM450 v3/v3

8Ω 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. Tested as per the EIA-426-A standard
  4. Measured on axis at 1W, 1m in 2π anechoic environment.
  5. Xmax derived from: (voice coil winding width-gap depth)/2.
  6. Small signal parameters measured after unit subjected to pre-conditioning signal.
