The Active twenty5.21i is the smallest in the range, but its impact and portrayal of any piece of music is far from small, thanks to PMC’s ATL bass loading and 2x100W active amplification.

Small but mighty – that’s the Active twenty5.21i: it may be the most compact model in the new Active twenty5i range, but it benefits from the same cutting-edge active amplification as the other models in the line-up, combining an active crossover with 100W of power for each driver. It also benefits from PMC’s Advanced Transmission Line technology, delivering bass impact you’d expect from a much larger design. It is ideal for small-to-medium listening environments where you still want detailed bass, ultra-realistic mids and delicate highs with maximum musicality. It’s equally happy to be mounted on a stand or a bookshelf and is an excellent choice for effects speakers in an immersive sound system.

The Active twenty5i series is an elegantly simple solution for any music lover: add a preamplifier or streamer with a volume control for a complete music system.
