Dayton Audio ND20FB-4 Rear-Mount 3/4" Neodymium Dome Tweeter

The Dayton Audio ND20FB-4 Dome Tweeter is a meticulously engineered soft dome tweeter designed to deliver exceptionally clear and detailed high-frequency reproduction. As part of the renowned ND Series, this component brings audiophile-grade performance to a compact and versatile form factor, making it an ideal choice for discerning audio enthusiasts and professional speaker builders alike.

This tweeter excels in a wide range of applications, from upgrading existing two-way loudspeaker systems to constructing bespoke bookshelf or floor-standing designs. Its high sensitivity and smooth frequency response make it particularly well-suited for use in near-field monitors, home theatre setups, and high-fidelity stereo systems where accurate treble reproduction is paramount. Whether you are designing a crossover network for a passive speaker or integrating it into an active multi-way system, the ND20FB-4 offers reliable and consistent performance.

Technically, the ND20FB-4 features a 19mm soft dome diaphragm that provides a natural, uncoloured sound. With a nominal impedance of 4 ohms and a sensitivity of 93 dB at 2.83V, it pairs efficiently with a wide variety of amplifiers. The tweeter’s low DC resistance (Re) of 3.2 ohms and a resonance frequency (Fs) of 2072 Hz ensure a smooth transition in crossover designs. Its compact 39.1 mm square frame allows for easy flush or surface mounting, while the low voice coil inductance (Le) of 0.03 mH contributes to extended high-frequency response and reduced distortion.

In summary, the Dayton Audio ND20FB-4 is a high-quality, affordable tweeter that combines technical precision with practical versatility, making it an excellent choice for any serious speaker project.
