The Model O grand piano is the largest of our Steinway baby grands. They differ from the salon and concert grands only in terms of their shorter body housing. This means it offers uncompromising sound while guaranteeing the ultimate in quality and craftsmanship, opening up a world of limitless musical expression. Just like all Steinway instruments, the smaller M-170 and S-155 baby grands follow the company founder’s aim “to build the best piano possible”. The Model O grand piano is also available as a Spirio. This 180 cm grand piano has been a source of joy and inspiration since the very early 1900's. With Spirio its the perfect combination of classical and modern. Its sound is exceptionally warm and rich for a grand piano of this relatively modest size. Dimensions: Width: 146,5 cm Length: 180 cm Weight: 286 kg
