Customer Reviews

"I first heard large PMC monitors when mastering an album in 2004, and I never forgot the experience. I walked away thinking "someday I will own those monitors." It took 15 years, and now that I have them, it's like I'm rediscovering music for the first time. I can't stop listening to everything I love - it's like I'm hearing it for the first time, but without blinders on. It's just unlike anything I've ever heard before, and I will be inviting all my clients and peers to come listen in my studio!"
Mr J, Spring Hill
"Wonderful speakers. Such a flat, natural, uncoloured sound. Such definition and clarity. Such perfect stereo imaging. Bravo."
Mr P, Wooburn Green
"The Speakers and the stands are simply amazing. Maurice did a spectacular job setting them up and I'll never go to another brand of speakers. PMC is simply the best. Many many thanks!"
Mr G, Los Angeles
"Already have a pair of the IB1S-Aii in another room, so broadly knew what to expect. Already had various positive comments from people who have never heard the brand or product before."
Mr A, Walsall
"I couldn’t work the way I do without your monitors. I always know I can trust what I’m hearing 100% - and this makes much of the detail work so much easier that it was with other monitors… the level of detail in the mid-range is extraordinary and I use low bass frequencies a lot in my productions, so it’s essential to have a very accurate picture of what’s going on down there. My PMC’s do this effortlessly."
Mr S, East Sussex
