T27TDFNC/GW is a High Definition precoated fabric dome tweeter with a wide, soft polymer surround and a powerful neodymium magnet system with a rear chamber.
Sonotex precoated fabric diaphragm with high consistency and excellent stability against variations in air humidity. The diaphragm is protected by a highly perforated hexagrid.
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.
Flexible lead out wires allow this driver to be used with low crossover frequencies. Powerful magnet system based on a high grade neodymium ring magnet for exceptional sensitivity and control.
Stiff and stable rear chamber made from extruded aluminium is equipped with cooling fins and black anodized for excellent heat transfer and high power handling.
The chassis is precision moulded from glass fibre reinforced plastic, and its front design offers optimum radiation conditions.
