Bang and Olufsen MS150

Introduced in the early ’80s, the MS150 was the largest domestic loudspeaker B&O ever built, packing a 25 cm subwoofer, 21 cm woofer, dome midrange, and tweeter into a sleek Danish cabinet that somehow makes “30 kg” look elegant. Thanks to B&O’s Uni‑Phase engineering—with laser holography, computer‑aided design, and all the nerdy magic of the era—it delivers flat, accurate, room‑shaking sound down to the 30–40 Hz range. These speakers were designed to be brutally honest, effortlessly powerful, and surprisingly refined. Rare, imposing, and very collectible, the MS150 is a vintage hi‑fi statement piece that sounds every bit as serious as it looks.
