K12H-200TC

  • 12" twin cone drive unit with extended high frequency response
  • 2" high temperature copper voice coil for increased reliability and 200Wrms (AES standard) power handling
  • Optimised cone neck/voice coil assembly for increased strength, minimising high frequency distortion and improving sound quality
  • Secondary cone terminated by pressure formed cloth dust cap for enhanced mid-band clarity
  • High efficiency magnet structure design delivers improved sensitivity
  • Double roll surround for greater excursion control and smooth frequency response

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.
