Atlantic City Convention Hall Organ
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 33,112 pipes! The organ weighs in at approximately 150 tons. The most impressive stop on the organ would have to be the 16 foot Ophicleide, which is the world's loudest stop. This stop has six times the volume of the loudest train whistle.

The Guinness Book of World Records credits the organ as the largest musical instrument ever created and the loudest musical instrument ever constructed.

Atlantic City Convention Hall Organ

The Convention Hall Auditorium Organ is the pipe organ in the Main Auditorium of the Boardwalk Hall in Atlantic City, New Jersey, built by the Midmer-Losh Organ Company. The great hall itself is also part of the world's largest pipe organ and was formerly known as the Atlantic City Convention Hall, which can seat 41,000 people in the main auditorium.

The massive organ has 33,112 pipes in 455 ranks, including a full-length 64 foot Diaphone Profunda, ten 32 foot ranks, and manual and pedal reeds that are under 100 inches of wind pressure, while most organs never exceed 10 inches of pressure. In total, there are 4 stops on 100 inches of wind pressure, and there are 10 stops on 50 inches of wind pressure, ear burtsing stuff, but all in order to fill the giant room with sound. The electric blowers that power the organ approach 1,000 horsepower, the kind of power needed to fill a hall larger than 15 million cubic feet. A tour of the entire organ takes 4 1/2 hours.

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.
