29TFF/W is a High Definition precoated fabric dome tweeter with an integrated
wide, precoated fabric surround.
Precoated Sonomex fabric diaphragm allows very tight production tolerances and
high consistency.
Wide Sonomex surround for low resonance, 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.
Two part front plate with smooth, slightly elliptical wave guide made from
elastomer provide excellent high frequency response and dispersion. The wave guide
conceals (and thus eliminates acoustic effects from) the magnet system screws.

The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees, mounted in a 0.6m by
0.8m baffle. Input 2.83 VRMS, microphone distance 0.5m, normalized to SPL 1m. The impedance is measured without baffle
using a 2V sine signal.
