 The lengthy pipework of the low registers in a church organ simply doesn't fit into a home, and so devices such as a quint, a Haskell bass, and a stopped pipe are employed to achieve the same sound but with more compact mechanisms.The action is also engineered for compactness.In early designs, the action was very simple and comprised a sprung arrangement where air was compressed in the lower chest of the organ, and depressing a key would open a pallet that would release the air up to the pipe ranks.
