Scan-Speak Illuminator D3004/606200 Dome Tweeter

The Scan-Speak Illuminator D3004/606200 Dome Tweeter represents a pinnacle of high-frequency driver engineering, delivering exceptionally detailed and natural sound reproduction. Designed for discerning audiophiles and serious loudspeaker builders, this tweeter excels in high-end home audio systems, studio monitors, and custom speaker designs where accuracy and transparency are paramount. Its refined performance makes it particularly suitable for critical listening environments and crossover designs requiring a premium-quality driver.

At the heart of this tweeter lies a 25.4 mm coated fabric dome, carefully engineered to provide smooth, extended frequency response with minimal distortion. The total Q factor of 0.38 ensures controlled damping and excellent transient response, allowing for precise integration into both two-way and multi-way systems. With a sensitivity of 91 dB SPL at 1 metre for 2.83 V, it pairs effectively with moderate-power amplifiers. The 4-ohm impedance and low DC resistance of 3 ohms facilitate straightforward crossover design, while the extremely low voice coil inductance of 0.02 mH contributes to outstanding high-frequency extension. Mechanical and electrical Q values of 2.2 and 0.46 respectively further demonstrate its carefully optimised damping characteristics. The tweeter features a 47.4 mm cut-out diameter and a mounting depth of 45.3 mm, secured via three screws for reliable installation. As part of the acclaimed Illuminator series, this driver sets a benchmark for natural, detailed high-frequency performance.
