Dayton Audio's compact, ultra-smooth ND25FA-4 soft dome tweeter features
excellent detail and high power handling. The small faceplate and neodymium
motor make it easy to keep center-to-center distance to a minimum for improved
off-axis response, and the exceptionally flat response above 3 kHz.
Key Features
Exceptionally flat treble response with low distortion
Compact round faceplate design is simple to install
High-strength neodymium motor with heatsink and ferrofluid cooling
Perfect for placement in car A-pillars
1" diameter voice coil for good off-axis dispersion and excellent power
handling
Clean, modern styling and appearance
This tweeter is smooth! 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 aluminum 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.
Choose the ND25FA-4 when you need detail that won't become fatiguing or
shrill at high volumes, for a highly refined presentation. 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.
