21-inch cast aluminium chassis neodymium magnet low frequency loudspeaker

  • Power rating: 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.
  • Continuous power rating: Defined as 3dB greater than the AES rating.
  • Sensitivity: Measured on axis at 1W, 1m in 2π anechoic environment.
  • Parameters: Measured after unit subjected to pre-conditioning signal.
  • Xmax: 0.5*(Hvc-Hg) + 0.25*Hg
  • Xmech: Maximum peak-to-peak excursion before damage.
  • Advanced temperature control using 3-channel tuned venting system provides highly efficient cooling across the frequency band
  • Voice coil typically operates at 30°C lower temperature than other leading drivers in this class
  • Polysiloxane laminated triple suspension provides much greater stability and improved cone displacement symmetry
