More Information



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.
