FTR12-2565D

  • 12" cast aluminium chassis mid/bass speaker provides 500W continuous power handling and 95dB sensitivity
  • 2.5" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss due to thermal compression
  • “M-Roll” surround provides progressive excursion control, generating a smoother frequency response
  • Intelligent heat management in both chassis and magnet assembly further minimizes distortion
  • Cost-effective unit, ideal for use in 2-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.
