PMC Active Twenty5i 21 Loudspeaker

PMC introduces an elegantly simple solution for any music lover – the Active twenty5i series. With optimised amplification built into every speaker, all you need is a preamplifier or streamer with an output volume control to create a world-class music system.

At PMC, we’re always striving for a closer connection with the music through greater transparency, purity and resolution. For over 30 years, we’ve been applying this thinking in the professional world through active speakers, with precision analogue crossovers feeding dedicated amplification optimised for each drive unit.

With the new Active twenty5i series, we’re bringing this approach to the best-selling twenty5i speaker series, with integrated electronics and amplification enabling superb performance and a fuss-free system without needing a separate power amplifier or integrated amp. Add a preamp or streaming device, and you have a complete high-resolution system without the clutter of multiple hi-fi components.

In the Active twenty5i series, each driver is directly coupled to an ideally matched 100W power amplifier, able to control the driver with a vice-like grip. Ahead of the power amps, a meticulously modelled analogue crossover splits the incoming signal, so each amplifier is only handling the frequencies appropriate to the driver it’s powering, guaranteeing ideal driver integration and a staggeringly pure, natural, and free-breathing sound.

It’s an elegantly simple solution for any music lover, reinventing the twenty5i speakers with even greater resolution and control and bringing you even closer to the music.

ATL, Advanced Transmission Line Technology

DEEPER, CLEARER, CLEANER BASS & MORE

• Greater detail & more natural
• A full, rich sound at any volume level
• Deeper bass from a smaller cabinet

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.

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.
