Scan-Speak Revelator R2904/700005 1" Ring Radiator

The Revelator R2904/700009 Ring Radiator Tweeter from Scan-Speak represents a pinnacle of high-frequency driver engineering, designed for audiophiles and professional loudspeaker builders who demand uncompromising performance. This tweeter excels in high-end home audio systems, studio monitors, and custom speaker designs where clarity, detail, and efficiency are paramount. Its ring radiator configuration ensures a wide, even dispersion pattern, making it ideal for both near-field listening and larger listening rooms, while its low resonance frequency allows for seamless integration with midrange drivers in two- or three-way systems.

Technically, the Revelator R2904/700009 boasts an impressive sensitivity of 94.5 dB (SPL 1m/2.83V), ensuring effortless high-frequency reproduction even with modest amplification. The extremely low voice coil inductance of 0.01 mH contributes to outstanding transient response and extended high-frequency extension. With a total Q factor (Qts) of 0.33 and a resonance frequency (Fs) of just 52 Hz, this tweeter offers remarkably low distortion and smooth roll-off characteristics. The 4-ohm impedance and 3-ohm DC resistance are optimised for stable amplifier loading. Mechanically, it features a 104.2 mm overall diameter, a 70 mm cut-out, and a 33.5 mm mounting depth, secured via a six-hole flange with 4.2 mm holes. The Revelator series is synonymous with precision, and this tweeter delivers exceptional clarity, airiness, and micro-detail, elevating any loudspeaker design to reference-level performance.
