Scan-Speak Illuminator R3004/602200 Ring Radiator Tweeter

The Scan-Speak Illuminator R3004/602200 Ring Radiator Tweeter represents a pinnacle of high-frequency driver engineering, offering audiophiles and speaker designers an exceptional component for critical listening applications. This ringdome tweeter is ideally suited for high-end home audio systems, studio monitors, and custom loudspeaker projects where accurate treble reproduction is paramount. Its unique ring radiator design ensures a wide, even dispersion pattern, making it perfect for both near-field and far-field listening environments, and it integrates seamlessly into multi-way speaker configurations.

Technically, this tweeter boasts a remarkably low resonance frequency of 42 Hz, enabling smooth crossover integration with midrange drivers. The voice coil inductance is an ultra-low 0.02 mH, contributing to extended high-frequency response and minimal distortion. With a sensitivity of 89.5 dB (1m/2.83V) and a nominal impedance of 4 ohms, it pairs efficiently with a wide range of amplifiers. The total Q factor of 0.4, combined with mechanical and electrical Q values of 2.3 and 0.48 respectively, ensures controlled damping and accurate transient response. The 26 mm ring radiator diaphragm and 43 mm cut-out diameter allow for straightforward installation, while the 62 mm overall dimensions and three-hole mounting pattern provide flexibility in enclosure design. Rated for a maximum power handling of 13 watts, this tweeter delivers clear, detailed treble with exceptional clarity and precision.
