H1283
The 22TAF/G is a High Definition metal dome tweeter with wide, coated fabric
surround.
The relatively small voice coil diameter and the wide surround combine the high
frequency behaviour of a ¾” dome with the low frequency characteristics of a 1”
dome.
A large ferrite magnet gives high efficiency.
The dome is precision formed from an aluminum/magnesium alloy for low mass and
high rigidity and stability. The precoated surround material gives high consistency
and excellent stability against variations in air humidity. An acoustically open
Hexagrid protects the dome diaphragm.
The voice coil is wound on an aluminum coil former with adequate venting holes
to eliminate noise from internal air flow. The coil is immersed in a low viscosity
magnetic fluid for high power handling capacity and simplified crossover design.
The chassis is moulded from a stiff and stable glass fibre reinforced polymer
material, and its front design offers optimum radiation conditions.
