Bang & Olufsen Beovox MS150 (1981) – Uni-Phase High-Fidelity Loudspeakers

 

The Beovox MS150 loudspeakers were designed with Bang & Olufsen’s Uni-Phase technology, ensuring linear phase and amplitude response for exceptionally accurate, distortion-free sound. Built to deliver true high-fidelity performance, the MS150 reproduces every detail of your music exactly as intended. With a 150W RMS power rating and an advanced overload protection circuit, these speakers confidently handle high listening levels. Their performance is the result of B&O’s integrated loudspeaker design approach, combining Fourier analysis, computer-aided simulation, and laser holography to refine cabinet resonance control, crossover precision, and driver integration. The MS150 features a monitor-grade subwoofer, an 8-inch bass driver, and a 64-litre cabinet, producing deep, clean, and powerful low frequencies. A 3-inch dome midrange—aperiodically tuned for optimal accuracy—delivers lifelike vocals, while the dedicated super tweeter ensures outstanding high-frequency clarity. Perfectly balanced across the full audio spectrum, the Beovox MS150 excels with all music genres, from delicate acoustic passages to dynamic, high-energy recordings. These speakers pair beautifully with the Beolab 8000 system and other premium hi-fi setups.
