PMC activetwenty5 21i Bookshelf Speakers

The Active twenty5i series - high-end audio made sleek and convenient with uncompromised performance.

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.

Advanced Transmission Line Technology

The source of PMC’s legendary natural, realistic sound is the Advanced Transmission Line (ATL) bass-loading technology, professionally proven all around the world.

ATL uses energy generated by the bass unit in a much more intelligent, efficient way than speaker designs based on ported or sealed boxes.
