Wilhelm Grotrian WG-23 Upright Piano
特點：
- The imported Kluge keyboard renders better touch, while the imported Renner hammers make even more beautiful sound
- Alaska spruce is used for the back pillars and the bottom material of the upper frame to increase the strength and stability of the resonance
- The use of imported German ROSLAU piano strings provides high strength, good elasticity, smooth and clean surface, and excellent quality
- The soundboard adopts NC numerical control code, rotary hole, shovel slope, nailing, and plucking shaft pin to ensure the accuracy of the soundboard code pressure and string production and the consistent transmission of tone color
- The iron plate is designed with a four-tone frame structure to ensure the stability of the piano
