Cumulative spectral decay
19mm High Fidelity dome tweeter with smooth, extended frequency
response. The chassis is injection moulded in high grade glass fibre
reinforced plastic. The diaphragm is made from a thin aluminium
sheet and suspended by a specially designed soft surround which allows
for a low fundametal frequency. A fine mesh grid protects the diaphragm
and carries a phase plate which compensates for a slight axial roll of
towards 20 kHz. The voice coil is wound on an aluminium voice coil
former with ventilating holes which eliminate problems connected with
resonances in the internal cavities. The voice coil windings are immersed
in magnetic fluid to increase short term power handling capacity, to
reduce the compression at high power levels and to significantly reduce
the Q factor.
