27TBFC/G is a High Definition metal dome tweeter with a wide, soft polymer surround and a rear chamber. 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. Stiff and stable rear chamber with optimal acoustic damping allows the tweeter to be used with moderately low crossover frequencies. Precision moulded chassis from glass fibre reinforced plastic, and its front design offers optimum radiation conditions.
