H1396
Compact design neodymium magnet tweeter for high quality speaker designs in
small cabinets or automobiles.
Sonolex precoated lightweight fabric diaphragm and suspension allows for very
tight production tolerances and high consistency.
Wide roll surround together with a double chamber magnet system results in a low
fundamental frequency.
Very low magnetic stray fields make this unit suitable for A/V systems.
The voice coil is immersed in magnetic fluid, allowing high power handling capacity
and simplified crossover design.
