PMC Audio Active Twenty5.21i Powered Bookshelf Speaker (Pair)

The PMC Audio Active Twenty5.21i powered bookshelf speaker proves that compact dimensions can deliver truly expansive sound. As the smallest model in the Active twenty5i range, it features PMC’s proven Advanced Transmission Line (ATL™) bass loading and a precision active crossover paired with 2 x 100W of built-in amplification, ensuring each driver performs at its absolute best. The result is authoritative, controlled bass, natural midrange clarity, and refined high frequencies that defy its size.  Designed for small to medium listening rooms, the Active Twenty5.21i offers exceptional realism, timing, and musical engagement, whether placed on dedicated stands, shelves, or used as part of an immersive audio system. With amplification integrated directly into the speaker, system complexity is reduced while performance is elevated—simply add a preamplifier or streamer with volume control. Elegant, efficient, and unmistakably PMC, the Active Twenty5.21i delivers studio-grade accuracy and emotional impact in a beautifully compact form.
