Dayton Audio ND25FA-4 1” Soft Dome Neodymium Tweeter 4 Ohm
Quick Overview:
Compact, ultra-smooth soft dome tweeter with excellent detail and high power handling. The small faceplate and tiny 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 3kHz makes crossover design an absolute breeze!
Product Highlights:
- Exceptionally flat treble response with low distortion
- Compact round faceplate design is simple to install
- High-strength neodymium motor with heatsink and ferrofluid cooling
- 1” diameter voice coil for good off-axis dispersion
- Clean, modern styling and appearance
Product Description:
This tweeter is smooth! The Dayton Audio ND25FA-4 is a 1” soft-dome tweeter that 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 that doesn’t become fatiguing or shrill at high volumes, for a highly refined presentation. The compact faceplate allows for close center-to-center spacing of drivers, making these tweeters perfect for line array use or D’Appolito (MTM) configurations with wide dispersion.
