• We at Bösendorfer have made use of our enormous competitive edge as the technology leader in computerised pianos
since 1985 and have significantly expanded that edge with CEUS.
• CEUS is available for all Bösendorfer grand pianos from 170 to 290 cm.
Retroactive installation in all existing Bösendorfer grand pianos (models 170 to 290) is possible.
