STANDARD SERIES
Acoustic instruments with soul
We have a completely individual approach towards the building of our Standard Series models, which enables us to devote the greatest care to each one. This produces instruments that despite their size arouse in both pianist and listener alike the emotions and atmosphere of a large concert hall. The pianos in this series are produced in three lengths and a colourful variety of finishes. These instruments are distinguished not only by their sound properties, but also by the fact that one can select a piano that perfectly suits the interior or hall for which it is intended.
P 159 BORA
The little big grand piano
Its size is the only thing that makes the Bora a small instrument. As soon as the hammers hit the strings, you will discover its wonderful, rich and surprisingly powerful sound. Once again we have put the very best materials, technology and design features of concert instruments into its construction. Its potential greatly transcends its actual size. Professional players favour it for practice purposes and domestic use.
