Dayton Audio TD25F-4 Dome Tweeter

The Dayton Audio TD25F-4 Dome Tweeter is a meticulously engineered soft dome tweeter designed to deliver clear, detailed high-frequency reproduction in a wide range of speaker projects. This 25mm driver is an excellent choice for audiophiles and DIY enthusiasts seeking to enhance their home audio systems, studio monitors, or custom loudspeaker designs with natural, uncoloured treble. Its versatile performance makes it equally suitable for two-way bookshelf speakers, multi-channel home theatre setups, or as a replacement driver in existing enclosures.

Technically, the TD25F-4 features a 4-ohm impedance and a sensitivity of 91 dB at 2.83V/1m, ensuring efficient power handling and easy integration with most amplifiers. The soft dome diaphragm, with a diameter of 25.4 mm, provides smooth frequency extension, while the low resonance frequency of 9 Hz contributes to a seamless crossover transition. Key electrical parameters include a DC resistance of 3.5 ohms, a voice coil inductance of just 0.04 mH, and a total Q factor of 0.94, indicating well-damped behaviour. The tweeter’s cut-out diameter is 69.9 mm, with an overall depth of 31.8 mm and a frame size of 93.5 mm, making it straightforward to mount in standard enclosures. With its combination of precise engineering and reliable performance, this tweeter is a superb choice for achieving articulate, airy highs in any high-fidelity loudspeaker design.
