With its ambition, technology, engineering and sheer bulk (a single monitor weighed 140kg), the KEF KM1 effectively redefined very high‑performance studio monitoring. But was it a success? The answer to that isn’t simple.

This is one of two sets thought to exist in North America, and one of a very small number manufactured by Kef to fulfill a need for a very high-output (pushing 120dB) studio monitor that also met the strict BBC requirements for neutral, un-colored playback, but at output levels impossible to achieve with other BBC monitors like the LS3/5A or ...
