This piano resembles Steinway's 5'10 grand piano, with engineered details born from the Steinway factory. here are 4 features on a Boston grand that sets them apart from competitors:

1. Steinway-derived duplex scaling → richer harmonic overtones
The GP178 uses duplex scaling, a design pioneered by Steinway & Sons, where the non-speaking sections of the string vibrate sympathetically with the main vibrating length
• Creates the “singing” Steinway-style sustain rather than a short, dry sound.
• Adds color and projection across the dynamic range

2. Wide-tail cabinet → larger soundboard than most 5'10" grands
The Boston GP178 uses a wide-tail case design, another Steinway concept, which increases the soundboard area beyond typical pianos of the same length.
• Soundboard vibrating area: ~1.30 m²
• Similar soundboard area to many 6'2" grands.

3. Solid Sitka spruce tapered soundboard → greater resonance and sustain
The GP178 uses a solid Sitka spruce soundboard, precisely tapered from 8 mm to 6 mm.
• thinner in the bass for more bass vibration
• stiffness in the treble for clarity.

4. Hard Rock Maple structural components → stability and tonal focus
The GP178 uses premium Maple hardwood structural elements, including:
• Hard Rock Maple inner rim (continuous bent rim)
• 11-layer Octagrip maple pinblock for better tuning Stability

Come hear the difference that Steinway makes available in its Boston line and enjoy savings on this floor pristine condition floor model.
