Dayton Audio CF18N-4 Dome Tweeter

The Dayton Audio CF18N-4 Carbon Fiber Neodymium Dome Tweeter delivers exceptional high-frequency clarity for discerning audio enthusiasts. This 18mm tweeter is ideally suited for custom loudspeaker designs, home audio upgrades, or professional monitoring systems where precise treble reproduction is essential. Its compact form factor also makes it an excellent choice for satellite speakers or multi-channel installations where space is at a premium.

Engineered with a lightweight yet rigid carbon fibre dome, this tweeter offers low distortion and extended frequency response, ensuring detailed and natural-sounding highs. The neodymium magnet motor provides high efficiency, with a sensitivity of 90 dB (1m/2.83V) and a 4-ohm impedance, making it easy to integrate into a wide range of crossover networks. Key technical specifications include a DC resistance (Re) of 3.54 ohms, a resonance frequency (Fs) of 1.1 kHz, and a total Q factor (Qts) of 1.2, which contributes to smooth roll-off characteristics. The voice coil inductance (Le) is a low 0.11 mH, aiding transient response. With a cut-out diameter of 36.9 mm and a mounting depth of 38.3 mm, this tweeter fits neatly into standard enclosures, secured via its four-hole flange.

Whether you are building a high-fidelity system or upgrading existing speakers, the CF18N-4 offers reliable, articulate performance that brings your audio projects to life.
