Evidence
Extremely occasionally, stops that sound two octaves below might be found, such as a 32′ contra violone on a manual or a 64′ gravissima or contra trombone on the pedals, as found on the John Wanamaker organ in Philadelphia and the Centennial Hall in Sydney, respectively. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1563
