PMC Active Twenty5.23i Floorstanding Speaker, Oak (Pair)

The PMC Active Twenty5.23i is an active 2-way floorstanding speaker with internal amplification and an active crossover, enabling a complete high-end system without a separate power amp.

The 23 has long been the most popular model in the range – and the Active version builds on that success. Weight and refinement in a still-slender floorstander format: that's the combination so many people love.

Why the Active Twenty5.23i?

Because it takes the virtues of the best-selling passive model and follows them through to the end. Active crossover, 2 × 100 W per cabinet and a long ATL turn the elegant floorstander into a speaker that fills medium-sized rooms with transparent, authentic dynamics – with bass down to 28 Hz that never thickens up. You don't need an amplifier stack, just a source with volume control.

What you hear

An open, honest sound with effortless depth and a cleanly layered stage. Voices sound natural, instruments get room to breathe. The .23i never pushes itself forward – it simply does what's on the recording, patiently at any volume.

Who is the Active Twenty5.23i for – and who isn't it for?

For anyone who wants a full-grown floorstanding speaker with high-end ambitions, without setting up stands or stacking power amps. Plainly: for very large rooms with high level demands, the bigger .24i is the more honest choice. And if all you want is quiet background music, you're paying for reserves you'll never use here.

Our verdict

The all-rounder of the range, and not without reason the favourite of many PMC listeners. Slim, versatile, honest – and wonderfully tidy in the rack thanks to the active technology. Once you've stopped counting boxes, you rarely want to go back.

Frequently asked questions

Do I need an amplifier for the PMC Active Twenty5.23i?

No, a power amp isn't needed. Each cabinet brings 2 × 100 W and an active crossover along. You just connect it to a source that controls the level – a preamp or a streamer with volume control, via XLR or RCA.

What room size suits the Twenty5.23i?

The .23i is ideal for medium-sized rooms. As a slim floorstander, its bass reaches down to 28 Hz thanks to the long ATL, without taking up much floor space. It fills the room with transparent dynamics and effortless depth – an all-rounder for most living rooms.

Floorstanding .23i or bookshelf .22i – which fits better?

The .23i is the slim floorstander with deeper bass (28 Hz) and its own stability – ideal if you don't want to set up stands. The .22i is more compact and needs stands or a sideboard. Same sound family, different form factor. We'll help you match it to your room.
