Petrofs are known for their warm, rich, singing tone, full of color. Petrof also offers as an option the Magnetic Balanced Action, which allows the player to quickly and easily change the touchweight in the range of ±4–5 grams simply by turning a knob. The Magnetic Accelerated Action, as it is known, is a special-order option on the grands.

The action is adjusted in the factory for a standard touchweight and is serviced in exactly the same way as a standard action. The new action also furthers the European Union’s stated environmental goal of phasing out the use of lead in pianos. These magnets allow for the removal of the usual lead counterweights in the keys and, according to the company, significantly alter the action’s dynamic properties. Petrof has also invented and patented a version of its new grand action that uses tiny opposing magnets on the wippens and wippen rail.

Most component parts are produced by Petrof or other Czech factories, including the hardware, plates, and cabinetry. Petrof recently introduced a series of six new grand piano models, named (in size order) Bora, Breeze, Storm, Pasat, Monsoon, and Mistral, from 5' 2" to 9' 2" in length. Currently Petrof manufactures 5,000 vertical pianos and 900 grands annually. Since the fall of the Soviet Union and the liberation of Eastern Europe, the various factories that were part of Musicexport have been spun off as private businesses, including Petrof, which is once again owned and controlled by the Petrof family. In 1965 Petrof, along with other piano manufacturers, was forced to join Musicexport, the state-controlled import-export company for musical instruments. In 1947, when all businesses in the Czech Republic were nationalized by the state, the Petrof family was forced out of the business. The Czechs have long been known for their vibrant musical-instrument industry, which also includes makers of brass, woodwind, and stringed instruments. Five generations of the Petrof family owned and managed the business, during which time the company kept pace with technical developments and earned prizes for its pianos at international exhibitions. The Petrof piano factory was founded in 1864 by Antonin Petrof in Hradec Králové, an old, historic town 100 kilometers east of Prague, in the present Czech Republic.
