SEAS loudspeaker tweeter 25TAFN/QG, 25 MM H0623-06 Compact neodymium magnet tweeter with a square chassis for high quality speaker design in small cabinets or automobiles. Aluminium/magnesium alloy diaphragm with pistonic behaviour throughout the audible frequency range, resulting in a good dispersion also above 10kHz. Sonotex surround for excellent mechanical linearity. A Hexagrid protects the diaphragm, and supports a phase plate which compensates for a slight axial roll off towards 20 kHz. The construction of the magnet system results in very low magnetic stray fields since the magnet is enclosed in a soft steel housing. Thus, this unit is immediately ready for Audio-video systems. The voice coil is immersed in magnetic fluid, allowing high power handling capacity and simplified crossover design.
