27TFF is a High Fidelity precoated fabric dome tweeter with an integrated widesurround.

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.

Optimally damped cavity in the pole piece controls and slightly lowers the fundamental resonance.

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