27TBF/G is a High Definition metal dome tweeter with a wide, soft polymer surround.
Aluminium/magnesium alloy diaphragm with pistonic behaviour throughout the
audible frequency range, resulting in a good dispersion also above 10kHz.
A Hexagrid protects the diaphragm, and supports a phase plate which compensates
for a slight axial roll off towards 20 kHz.
Sonomax surround for low resonance and excellent mechanical linearity.
Voice coil windings immersed in magnetic fluid increase short term power handling
capacity and reduce the compression at high power levels.
Optimally damped cavity in the pole piece controls and slightly lowers the
The chassis is precision moulded from glass fibre reinforced plastic, and its front
design offers optimum radiation conditions.
