ACTIVE Twenty5.24i

The largest active model in the series, Active twenty5.24i is a two-way speaker that sounds like a much larger three-way design.

Driven by 200 Watts of optimised internal amplification per speaker, and with an active crossover to ensure each driver is powered optimally, it will fill even large listening rooms with compelling musical performances.

Premium 19 mm soft dome tweeters and 6.5-inch mid / bass drivers are seamlessly integrated and combine with PMC’s classic ATL™ technology to deliver a high-fidelity experience like no other – just add a preamplifier, or a network player with volume control for a complete high-end system taking up minimal space.

The Active twenty5i series delivers high-end audio, made sleek and convenient with uncompromising performance.


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.
