Scan-Speak Ellipticor D3404/552000 1.5" Dome Tweeter

The Scan-Speak Ellipticor D3404/552000 Dome Tweeter represents a pinnacle of high-frequency engineering, delivering exceptionally clear and detailed sound reproduction for the most discerning audiophile systems. With a remarkable sensitivity of 97 dB, this tweeter is ideally suited for critical listening applications, including high-end home stereo setups, studio monitors, and bespoke loudspeaker designs where transparency and airiness are paramount. Its robust construction ensures it can handle demanding musical passages with ease, making it a superb choice for both two-way and multi-way configurations.

At the heart of this driver lies a 38.1mm coated fabric dome, which combines low moving mass with excellent damping properties to minimise distortion and resonance. The voice coil inductance is an ultra-low 0.01 mH, contributing to extended high-frequency response and exceptional transient speed. Key parameters include a resonance frequency of 475 Hz, a total Q factor of 0.57, and an impedance of 4 ohms, ensuring seamless integration into crossover networks. The mechanical and electrical Q values of 5.25 and 0.63 respectively highlight a carefully balanced design for natural, uncoloured sound. With a maximum power handling of 3 watts and a DC resistance of 3 ohms, this tweeter is engineered for precision and longevity. The Ellipticor series continues Scan-Speak’s legacy of producing reference-grade transducers, and the D3404/552000 stands as a testament to their commitment to sonic excellence.
