Don't be fooled by its cute looks and tiny proportions — the SubSeries 100 Compact Powered Subwoofer may be small, but it's got plenty of might.

Unlike typical desktop products, SubSeries 100 is thoroughly engineered by PSB Speakers, one of the most highly reviewed brands of high-end speakers in the world and winner of countless awards in its 40-year history. SubSeries100 is solid, powerful, and articulate.
