27TFFC is a High Fidelity precoated fabric dome tweeter with an integral wide
surround and a rear chamber.

Sonolex precoated lightweight fabric diaphragm with high consistency and excellent
stability against variations in air humidity.

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.

The chassis is precision moulded from glass fibre reinforced plastic, and its front
design offers optimum radiation conditions.
