Seas 27TAFNC/D H1397-04 Magnesium Dome Tweeter

Compact neodymium magnet tweeter for high quality speaker design in small cabinets and automobiles. Aluminium/magnesium alloy diaphragm with pistonic behaviour throughout the audible frequency range, resulting in a good dispersion also above 10kHz.

Wide roll Sonomex surround together with a double chamber magnet system results in a low resonance frequency. The critically designed diffusor compensates for a slight axial roll off towards 20 kHz and reduces resonances above 20kHz.

Very low magnetic stray fields makes this unit suitable for A/V systems. Voice coil immersed in magnetic fluid, allowing high power handling capacity and simplified crossover design.



  • power handling (continuous/programme) = 90/220 W
  • frequency range = 2500-30000 Hz
  • resonance frequency fs = 1170 Hz
  • impedance R = 4 Ohm
  • sound pressure level SPL = 90 dB (2,83V; 1m)
  • DC resistance Re = 2,7 Ohm
  • force factor BL = 1,9 N/A
  • voice coil inductance L = 0,03 mH
  • effective piston radiating area Sd = 7,5 cm2
  • effective mechanical mass incl. air load mms = 0,3 g
  • voice coil diameter = 26 mm
  • maximum peak linear excursion vibration xlin = +/- 0,55 mm
  • mounting diameter d = 46 mm
  • overall diameter d = 53 mm
  • mounting depth (not countersunk) t = 21,5 mm
