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.
