SB Acoustics SB29BNC-C000-4 Dome Tweeter

The SB29BNC-C000-4 Beryllium Dome Tweeter from SB Acoustics represents a pinnacle of high-frequency driver engineering, designed to deliver an exceptionally refined and detailed treble response. This tweeter is ideally suited for discerning audiophiles and professional loudspeaker designers seeking to build or upgrade high-end two-way or multi-way systems where transparency and airiness are paramount. Its remarkable sensitivity and low distortion make it an excellent choice for both nearfield monitoring and larger listening environments, ensuring every nuance of the recording is faithfully reproduced.

At the heart of this driver lies a 29mm beryllium dome, renowned for its outstanding stiffness-to-weight ratio, which enables piston-like behaviour well beyond the audible range. With a sensitivity of 95 dB at 1 metre for 2.83V, it pairs effortlessly with moderate-powered amplifiers. The tweeter features a low DC resistance of 3 ohms and a nominal impedance of 4 ohms, complemented by an exceptionally low voice coil inductance of just 0.05 mH, ensuring superb transient response. The total Q factor of 0.69, derived from a mechanical Q of 1.36 and an electrical Q of 1.4, allows for flexible crossover design, with a recommended crossover frequency of 2600 Hz using a 12 dB/octave slope. Capable of handling up to 80 watts, this tweeter offers a resonance frequency of 95 Hz and a mounting cut-out diameter of 72 mm, with a depth of 33.6 mm, making it a versatile and high-performance choice for serious audio projects.
