Model 225

The Bösendorfer half concert grand has a very wide dynamic sound range considering its size, which results from its unique design and construction. It can produce many different colours of sound, allowing the pianist to play from the softest Pianissimo to the loudest Fortissimo. The Model 225 has four additional sub-bass keys, extending not only the bass range of the piano to bottom F, but also providing a larger soundboard to produce more volume when required to do so. With this conception the Model 225 is ideally suited for chamber music concerts.
