-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.
