PETROF P 159 Bora Acoustic Royal

PETROF P 159 Bora compact grand piano

PETROF P 159 Bora delivers a sound richer and more powerful than expected from its 159 cm body. Its particularly full middle register, controlled bass, and clear treble create a professional grand piano character for smaller spaces.

PETROF's romantic sound philosophy

PETROF continues the European piano-making tradition established in the Czech Republic since 1864. The resonance spruce, model-specific string scale, and individual hammer voicing for each instrument create a soft, rounded, and singing tonal character. The P 159 Bora presents this sound philosophy with bass depth, middle register color, and treble projection suited to its size.

Resonance spruce soundboard

The resonance spruce soundboard, with an active area of 1.019 m², is tapered to suit the model for free transmission of string energy and reinforced with 10 spherical or asymmetric ribs. This structure creates long sustain, natural register transitions, and a wide dynamic range.

Construction and string system

The wet sand-cast iron plate supports high string tension. The multi-layered beech pinblock, beech-maple inner rim, and solid maple bridges work together for resonance transmission and tuning stability. Röslau steel strings, Degen copper windings, copper agraffes for keys 1–59, and a front-rear duplex system refine the harmonic structure.

Action and keyboard

The RENNER–PETROF action provides rapid repetition, precise control in pianissimo, and stable response in powerful dynamics. Premium German hammer heads are individually voiced. Tangentially cut spruce keys are individually balanced, and ebony black keys offer a natural and durable surface. Unacorda, sostenuto, and sustain pedals create full expressive possibilities for the classical grand repertoire.
