The Ronisch piano has long been a favourite among piano teachers due to its fine, clear tone and highly consistent manufactured quality. Anyone looking to get a Ronisch is advised to look for instruments made before the second World War, as the original factory in Dresden, Germany was destroyed by allied planes in the latter stages of the war.
All of the manufacturing equipment was lost.
The factory was re-established in Leipzig after the war, but has never manufactured pianos of the same tonal beauty as did the original.
Carl Ronisch, was one of the foremost pioneers of piano-building in his time. He was first to use a full cast-iron plate in the piano, employing five struts and completely covering the wrest-plank (pin block), which for the first time, allowed a high-tension scale.
This is considered the beginning of the use of full cast-metal plates and is today, standard in the industry.
Ronisch instruments have won gold medals in the world exhibitions in Sydney, Amsterdam, Melbourne, Chicago and Paris.
