Petrof ceremonially unveiled the first ANT.PETROF model after seven years of development in 2014 in honour of Antonín Petrof, who founded the firm in 1864. Over the next two years they completed the brand's portfolio - it comprises two grand pianos (AP 275, AP 225) and one upright (AP 136). Only the most experienced of PETROF's specialists are involved in its construction, using the best quality European materials and technology. The result is a timeless design and a unique sound, of particular appeal to the most discerning customers.
Its tremendous sound reaches into every corner of any concert hall in the world. At the same time it remains true to its roots and respects the colourful, romantic and rounded tone of PETROF instruments. It may be a giant, but its elegance and sensitivity are remarkable. An instrument that breathes life into the wildest dreams of the artistic spirit, while opening the hearts of the most demanding listeners
TheANT. PETROF 275was the first instrument of its name, and is the PETROF company flagship. The eyes of the world watched over its five years of development and two years of testing. This instrument brought many innovations to the pianomaking craft, some of which have since been patented, and it has come to symbolise modern technologies while at the same time preserving the traditional techniques of the greatest pianomaking craftsmen. In particular its completely new construction, first class materials and careful processing make it an impressive instrument.
Solid maple bridges efficiently transfer the vibrations of the strings to the soundboard. These newly designed bridges have been profiled to reduce mass resulting in an increase in energy transfer which produces exceptional bass response and treble transmission.
Computerized drilling (CNC) of the cast iron plate creates an accurate and consistent framework for precision scale design. Exact speaking lengths of the strings and duplexes result in optimal vibrations which produce a pure, singing tone. Open areas of the cast iron enable greater resonance coming from the soundboard.
The European solid spruce soundboard delivers not only a wide dynamic range but also delivers PETROF’s characteristic romantic tone. Measuring in at 2,253 m2of surface area, the AP 275 contains sufficient power to fill any concert venue.
The solid beech wood lattice frame ensures the structural support to resist the nearly 20 tons of string tension. This robust design is built with rigidity for longevity.
The key bed is a three-layer cross-grain laminate of solid wood that creates a stable environment for consistent and even action regulation which is sought after by the most discerning pianists.
