About Monitor Audio

On one level, this is simple to answer: it’s sound that comes as close as possible to what the artist heard in the recording studio. The reality is far more complicated. For starters, anyone who has been in a recording studio will be aware that they don’t always sound fantastic. Sorry to dispel that myth, but it’s just a fact. Monitor Audio loudspeakers sound truthful and natural; they are engineered to reproduce music as the artist intended. A subtle but important difference. At its core, Monitor Audio’s mission is to develop loudspeakers that impose themselves as little as possible. Speakers that let the recording do the talking.
