Description
The Dayton Audio ND25FA-4 1″ soft-dome tweeter combines an exceptionally flat response above 3 kHz with a compact round faceplate for a clean, modern appearance that integrates easily into any design. The tiny yet powerful neodymium motor structure features an aluminium heatsink and ferrofluid cooling for low power compression and improved long-term power handling. A copper pole cap within the motor further reduces distortion and inductance effects.
Designed for a highly refined presentation and it won’t become fatiguing or shrill at high volumes. The compact faceplate allows close center-to-center spacing of drivers, making these tweeters perfect for line array use or D’Appolito (MTM) configurations with wide dispersion.
