The T29CF001 is a High End, High Efficiency 29mm fabric dome tweeter with a wide
surround.
An optimally shaped dome and integrated wide surround manufactured by SEAS
from SONOMEX ensure excellent performance and consistency.
A powerful magnet system based on an axially magnetized NdFeB ring magnet
provides efficient ventilation and damping of the cavity behind the dome. Low
viscosity magnetic fluid provides excellent cooling while maintaining a low
resonance frequency.
A generously underhung voice coil with flexible lead-out wires ensures low
distortion and allow this driver to be used with low crossover frequencies.
A 6mm precision machined aluminum front plate with moderate horn loading
combines linear frequency response with high efficiency. The front plate is Nextel
painted to obtain a durable and attractive finish.
A substantial injection moulded rear chamber made from zinc eliminates unwanted
chamber wall resonances and conducts heat away from the magnet system.

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.
