PETROF P 194 Storm Acoustic grand

PETROF P 194 Storm acoustic grand piano

PETROF P 194 Storm is the largest 194 cm model of the Standard Series. Its powerful sound potential, warm and sensitive pianissimo, wide dynamic reserve, and brilliant treble make it a versatile professional instrument across genres.

PETROF's romantic sound philosophy

PETROF continues the European piano-making tradition established in the Czech Republic since 1864. The resonant spruce, model-specific string scale, and individual hammer voicing for each instrument create a soft, rounded, and singing tonal character. The P 194 Storm presents this sound philosophy with bass depth, mid-register color, and treble projection suited to its size.

Resonant spruce soundboard

The 1.311 m² active area resonant spruce soundboard is thinned according to the model to freely transmit string energy and reinforced with 12 spherical or asymmetric ribs. This structure creates a long sustain, natural register transitions, and a wide dynamic range.

Construction and string system

The wet-sand-cast iron frame withstands 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 1–50, 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 fortissimo. 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 provide full expressive capabilities for classical grand piano repertoire.
