Scan-Speak Illuminator R3004/662000 1" Ring Radiator

The Scan-Speak Illuminator R3004/662000 Ring Radiator Tweeter represents a pinnacle of high-frequency engineering, delivering exceptionally precise and airy sound reproduction. Designed for discerning audiophiles and professional loudspeaker builders, this tweeter excels in high-end home audio systems, studio monitors, and custom speaker projects where clarity and imaging are paramount. Its advanced ring radiator topology ensures a wide, even dispersion pattern, making it ideal for both two-way designs and multi-way configurations that demand seamless integration with midrange drivers.

At the heart of this transducer lies a 25.4 mm ring dome diaphragm, which combines the benefits of a traditional dome with the controlled breakup behaviour of a radiator. The remarkably low resonance frequency of 52 Hz allows for a lower crossover point, reducing strain on the tweeter and enabling smoother transitions. With a sensitivity of 90.4 dB (1m/2.83V) and a nominal impedance of 4 ohms, it offers excellent efficiency and is straightforward to integrate into most crossover networks. The total Q factor of 0.48, alongside an extremely low voice coil inductance of just 0.03 mH, ensures outstanding transient response and minimal distortion. Rated for 15 watts maximum power handling, this Illuminator Series tweeter delivers refined, fatigue-free listening with stunning detail and depth.
