TF1230SL

  • 12" Bass and mid-range driver providing 97dB sensitivity and 350Wrms (AES standard) power handling
  • 3" high temperature copper voice coil wound on polyimide for increased reliability
  • Reduced inductive rise, leading to greater mid-range sensitivity; beneficial for many 12" driver applications
  • Kevlar-loaded cone with sealed surround and damping for reduced distortion.
  • Double roll surround provides exceptional linearity at extremes of cone excursion
  • For use in 2-way or compact 3-way systems

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.
