SubSeries 150, PSB has reimagined the subwoofer. Most subwoofers are large cubic forms that don’t often fit very well in your living room. The SubSeries 150 on the other hand, is a compact, slim, rectangular shape, allowing it to slip in easily beside, behind, or underneath living room furniture. This versatile and decor-friendly design with a beautiful curved gloss black cabinet also offers several clever installation options.
