SB Acoustics Satori TW29BNWG-4 Beryllium Tweeter

The SB Acoustics Satori TW29BNWG-4 Beryllium Tweeter represents a pinnacle of high-frequency driver engineering, designed to deliver exceptionally clear and detailed sound reproduction. This 19 mm dome tweeter is ideal for discerning audiophiles and professional loudspeaker designers seeking to build or upgrade high-end two-way or multi-way systems where transparency and low distortion are paramount. Its remarkable sensitivity makes it particularly well-suited for use in both near-field monitoring and larger listening environments, ensuring every nuance of the recording is faithfully rendered.

At the heart of this driver lies a pure beryllium dome, a material chosen for its outstanding stiffness-to-weight ratio, which enables pistonic behaviour well beyond the audible range and virtually eliminates break-up modes. The technical specifications underscore its performance pedigree: a sensitivity of 97 dB (1m/2.83V) ensures effortless dynamics, while an incredibly low voice coil inductance of just 0.02 mH contributes to extended high-frequency response. The motor system is precisely controlled, with a Qms of 2.1, Qes of 0.6, and a total Qts of 0.46, indicating excellent damping and transient behaviour. A low resonance frequency of 7 Hz and a DC resistance of 3 ohms complete the picture of a highly refined, 4-ohm design.

This tweeter is a testament to SB Acoustics' commitment to sonic purity, offering a level of resolution and airiness that transforms the listening experience.
