The Boardwalk Hall Auditorium Organ, 64-foot Diaphone, Dulzian demontration..
The organ possesses a unique stop in the organ world, the 64' Diaphone-Dulzian in the Right Stage chamber (Pedal Right division), one of only two true 64' stops in the world. (The other 64' stop is the Contra-Trombone reed stop in the Sydney Town Hall Grand Organ). The Diaphone-Dulzian's low-C pipe stands 59' (18 m) tall, weighs 3,350 pounds (1,675 kg), and produces a frequency of 8 Hz (the sound of the vibrating pallet is described as "a helicopter hovering over the building"), a tone that is more felt than heard. The pipe stands upright for about 40 feet (12 m), the remainder is mitred (turned) towards the Right Stage chamber's grill. All pipes taller than 32 feet (9.8 m) are designed in this manner. The Diaphone-Dulzian rank spans from C3 to g²; it is sufficiently extended so that the 64', 32', 16', 8' and 4' unison stops, and the 42²/3', 211/3' and 10²/3' mutation stops, may be drawn from the same rank. No other extension rank in the world spans that far. Also, when the 64' and 42²/3' are combined, the resultant tone simulates a 128' stop, equivalent to a 4 Hz tone on low C.
