-TWEETER 25MM DAYTON AUDIO NDFA-4-
 Tweeter dome Neodynium Magnet 4Ω ⌀ 25mm

This soft dome tweeter offers an excellent level of detail and respectable power thanks to its heat sink in a compact format. The small front plate and the small neodymium magnet motor allow the design without front edge for example for better off-axis impulse response, with an exceptionally flat frequency response that is easy to filter from 3000 Hz.


Its affordable price also allows the design of 6-channel speakers in MTM from Appolito or acoustic line. This tweeter is equipped with a copper coating on its polar part lowering the eddy currents (reduction of distortion and inductance). The 25mm copper coil has a Ferrofluid treatment increasing the permissible power.

Avis sur ND25FA-4
Je me demandais bien ce que je pouvais avoir comme rendu avec ce tweeter à moins de 13€.
Après l'avoir associé avec une paire de Dayton Audio ND91-4, ce petit tweeter va au delà de ce que je pouvais attendre. Finesse de l'aigu, linéarité en fréquence dans l'axe et hors axe, jamais agressif même à fort niveau.
Un excellent choix pour vos petits projets d'enceintes 2 voies. Filtré pour ma part à 3.2kHz en 3ème ordre à -3dB, le résultat est au rendez-vous.
N'hésitez pas, très bon rapport qualité prix.
