The twenty5i range consists of four two-way loudspeakers. Ranging from this compact shelf-mounting twenty5i.21 to the flagship floorstanding twenty5i.26.
Although the twenty5.21i is the most compact model in the new range, there’s nothing small about the sound, which has the impact you’d expect from a much larger cabinet, thanks to PMC’s Advanced Transmission Line technology. The speaker is ideal for use in small-to-medium listening environments where space is at a premium, but where you still want detailed bass, ultra-realistic mids and delicate highs with maximum musicality. Equally happy mounted on a stand or a bookshelf, the twenty5.21i offers maximum flexibility for placement, and also makes an excellent choice for effects speakers in an immersive sound system.

PMC’s core belief is that the same ultra-high resolution loudspeaker, if properly designed, can be used throughout the entire recording chain. That’s why their designs are employed at every stage of music-making, from film soundtrack composers’ music rooms to recording studios through to the home, preserving the essence of the original performance exactly as the artist intended. Because the characteristics and tonality of all PMC speakers, from large to small, are essentially the same, it’s a simple matter to mix and match different models to create your perfect immersive audio system.
Advanced Transmission Line
ATL uses energy generated by the bass unit in a much more intelligent, efficient way than speaker designs based on ported or sealed boxes. In ATL loudspeakers, the highly braced cabinet is lined with a multitude of custom-designed acoustic materials that absorb all but the very lowest frequencies. These exit from a front-panel vent, extending the low-frequency response, and creating the impression of a far larger speaker with an extra, ultra-high-quality bass unit.
ATL improves more than just the bass response: because the low end is clean and clear, it doesn’t mask the rest of the music. Vocals, in particular, are beautifully projected and ultra-vivid. ATL loudspeakers offer another benefit. The ATL bass extension does not change with volume level — so even when listening quietly, the bass sounds balanced and well defined.
