19mm High Fidelity dome tweeter with smooth, extended frequency
response.

Aluminium diaphragm suspended by a specially designed soft Sonotex surround
which allows a low fundamental frequency.

Double magnet reduces stray fields around the magnet system and allows the unit
to be used in close proximity to a CRT. The double magnet also gives a higher
sensitivity.

Fine mesh grid protects the diaphragm and carries a phase plate which compensates
for a slight axial roll off towards 20 kHz.

Voice coil windings immersed in magnetic fluid increase short term power handling
capacity and reduce the compression at high power levels.
