ACTIVE Twenty5.23i

Already the best-selling PMC model in passive form, the Active Twenty5.23i adds an active crossover and 2 x 100 Watts of amplification in each speaker.

This pairing creates an elegant floor-standing design, even more capable of filling medium-sized rooms with transparent, authentic dynamics and effortlessly extended bass.

With the choice of finishes shared across the Active twenty5i range, this compact floorstander blends unobtrusively into any room. Reviewer Chris Kelly said of the passive 23i: "Pair them with a high-quality amplifier and a good source and you will never regret your purchase." That is just what PMC have done with the Active 23i, building in the amplification for a just-add-source music solution.

With 2 x 100 W of amplification in each speaker, the Active twenty5i series just needs a preamplifier or streamer with volume control for a world-class music system.


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 Professional Monitor Company was founded in 1991 by Peter Thomas of the BBC and Adrian Loader of FWO Bauch.

Their combination of knowledge and a life-long passion for music led to the production of PMC’s first product, which was snapped up by BBC Maida Vale Studios and Metropolis Mastering and has remained the world’s reference ever since. PMC are one of the very few companies who have been awarded an Emmy for their contribution to recording excellence., and the company reigns supreme throughout the leading mastering houses, broadcasters and much of the professional world.

PMC believe a good loudspeaker should be able to relay the purest intentions of the artist without colouration – The ideal solution for both studio & home.
