Primarily organ builders, harpsichord makers, music theorists, acousticians, and advanced performers or composers working with the extreme low registers of keyboard instruments.
It is a highly specialized term from a specific technical field (music theory/organology). Most musicians refer simply to 'the lowest octave' or use specific note names (like C2) instead.
