ATOHM SD20ND04F Speaker Driver Dome Tweeter Neodymium 100W 4 Ohm 93dB Ø2cm

The SD20ND04F is a tweeter equipped with a neodymium motor, a treated silk dome and a 20mm coil with CCAW (copper and aluminum alloy) wire.

GRACe to the lightness of the mobile crew and the headliner with a specific profile, the sensitivity level is 93dB.

The facadeof this tweeter is made of injected aluminum (absence of parasitic vibrations) and benefits from the ADP (Anamorphic Dispersion Patterns) technology.

This ATOHM specificity ensures better dispersion off-axis and limits spurious reflections at very high frequencies (bandwidth extends up to 25 kHz in the axis).
In additione, the aluminum coil holder and the ferrofluid air gap ensure excellent thermal dissipation of the calories generated by the voice coil (high power holding without compression detrimental to listening).
