The HiVi B1S Shielded Aluminum Mid/Tweeter is a precision-engineered dome tweeter designed to deliver exceptionally clear and accurate high-frequency reproduction. As part of the respected BS series, this compact driver brings professional-grade performance to a wide range of audio applications. Whether you are building high-fidelity loudspeakers, upgrading existing multi-way systems, or working on custom audio projects that demand detailed treble response, the B1S offers a reliable and sonically refined solution. Its shielded construction also makes it suitable for use in environments where magnetic interference must be minimised, such as near CRT displays or sensitive recording equipment.

Technically, the B1S features a 25.4 mm aluminium dome diaphragm that provides excellent stiffness-to-weight ratio for low distortion and extended frequency response. With a nominal impedance of 8 ohms and a DC resistance of 6.5 ohms, it integrates easily into standard crossover networks. The tweeter exhibits a total Q factor (Qts) of 0.56, with mechanical (Qms) and electrical (Qes) values of 2.57 and 0.68 respectively, indicating well-damped behaviour. Its sensitivity is rated at 79 dB SPL (1m/2.83V), and it can handle up to 2 watts of power. The compact dimensions—35.8 mm overall diameter with a 29 mm cutout and only 13.2 mm depth—allow for flexible flush or surface mounting. This shielded aluminium dome tweeter is an excellent choice for achieving articulate, airy highs in your next audio build.
