Haut-parleur d'aigu (tweeter) SEAS T25C003
[E0036-06 T25C003] Avis/Critiques

The T25C003 is a 25mm fabric dome with moderately high efficiency. It is the tweeter of choice for those who want the most precise and realistic reproduction of the high frequency audio range. A wide, soft polymer surround designed to give high stability without magnetic fluid damping.
Flexible lead-out wires which ensure a good connection between voice coil and terminals. This arrangement also helps to prevent lead breakage due to the large excursions encountered when low crossover frequencies are used.

6 mm solid metal front plate with a slight loading characteristic which ensures linear frequency response, and a stiff and stable connection to the cabinet. A substantial injection-moulded rear chamber, with complex internal shape and reinforcing ribs, which eliminate unwanted chamber resonances and reflections.

A double magnet system which increases sensitivity and provides better control of the voice coil. This system also reduces the magnetic stray fields, making the T25CF003 an ideal choice in high end A/V applications.

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.
