How Low Can You Go?

Boardwalk Hall Auditorium Organ

The organ at the Boardwalk Hall Auditorium in Atlantic City, New Jersey is an record-setting mechanism. Guinness World Records has three entries dedicated to it:

  • With an estimated 33,116 pipes, it is the largest pipe organ ever constructed. These pipes are located in eight different chambers throughout the Auditorium. The organ’s main console is the biggest in the world. It has 1,235 stop tabs controlling 587 flue stops, 265 reed stops, 35 melodic percussions, 46 non-melodic percussions, 164 couplers, 18 tremolos, 120 swell pedal selectors for the 6 swell pedals controlling 15 swell boxes, and a stop crescendo pedal. The console is also the only one in the world with 7 manuals.


    The world’s largest pipe organ was built between May, 1929, and December, 1932, by the Midmer-Losh Organ Company of Merrick, Long Island, New York. It boasts seven manuals and has 1,439 stop keys, as well as 1,255 speaking stops, 455 ranks, and over 33,000 pipes.

  • It also happens to be the largest musical instrument ever constructed. The 64 foot tall Diaphone Profunda, whose low CCCCC is 64′ 9″ long, 10 inches square at the base, 36 inches square at the top, and 3 inches thick, is made from a single tree. The 12 lowest pipes contain more than 10,000 board feet of lumber, enough to build a house. There are ten 32 foot pedal ranks. The 32 foot Open Diapasorns low CCCC is 38 feet 6 inches long and weighs more than a ton.  The entire organ weighs in at 150 tons. A tour of the entire organ takes 4.5 hours.
  • It is the loudest musical instrument ever made. The 16 foot Ophicleide has six times the volume of the loudest train whistle. The eight blowers that power the notes produce 36,000 cubic feet of wind per minute.

    The 64-foot Diaphone-Dulzian stop is the largest reed/diaphone stop in the world. It weighs 3,350 pounds and produces a frequency of 8 Hz. Human ears typically register nothing lower than 20 Hz, so the lowest notes produced by the organ are felt, more than heard.
