Yamaha B20 TransAcoustic™ Piano: Powerful Resonance, Infinite Versatility
The Yamaha B20 TransAcoustic™Â (116cm) takes the innovation of the TC3 system and pairs it with the enhanced acoustic power of the B20 cabinet. This hybrid masterpiece offers a deeper, more resonant soundboard and longer strings, providing a richer “speaker” for the TransAcoustic™ technology.
Whether you are playing as a traditional acoustic, practicing silently with headphones, or using the soundboard to amplify digital voices at a controlled volume, the B20 TransAcoustic™ delivers a premium, immersive experience for the modern pianist.
Core Acoustic Excellence
The B20 TransAcoustic™ is built upon a superior acoustic foundation, providing the physical depth required for truly expressive play:
-
Larger Yezo Spruce Soundboard:Â The 116cm height allows for a bigger soundboard, which acts as a more powerful “speaker” for the TC3 system, resulting in a richer and more commanding tone.
-
Enhanced Structural Stability: Supported by five heavy-duty back posts, ensuring maximum tuning stability and resonance.
-
CFX-Derived Hammers:Â Double wool-felted hammers provide a clear, sustained, and responsive tone when playing in full acoustic mode.
-
New Full-Width Music Stand:Â Ample space for sprawling scores, making it ideal for the progressing student or dedicated hobbyist.
The TransAcoustic™ TC3 Advantage
The TC3 system transforms the B20 into an instrument that adapts perfectly to your environment:
-
Superior Volume Control:Â Enjoy the sensation of an acoustic piano “out loud” but at a volume that suits your surroundings. The soundboard amplifies the digital signal, allowing you to play at a whisper or a roar.
-
Everything a Silent Piano Can Do: Plug in headphones to access the high-definition Yamaha CFXand Bösendorfer Imperial samples for total privacy without disturbing anyone.
-
Hybrid Sound Layering:Â Layer digital voices like strings, choir, or electric piano over the natural acoustic sound of the B20 strings for a breathtaking, multi-dimensional performance.
-
Bluetooth Audio Streaming: Use your piano’s soundboard as a high-fidelity Bluetooth speaker. Stream backing tracks or favorite songs from your device and play along with the natural resonance of real wood.
