The GS150 grand piano is a 5’ instrument of exceptional power, elegance, and quality. It remains the only piano of its size and price range to offer vertically-laminated bridges (a Steinway-pioneered feature typically found on grand pianos $30,000 and above). It is one of the few true wide-tail designs. Its scale designs are computer-generated, and its action competes with a Yamaha CX without question.
For homes seeking a full and complex tone, either for casual playing, elegant features, or more advanced student progress, the Johannes Seiler GS150 should be seriously considered by any buying family fortunate enough to have it available in their market.
The Johannes Seiler GS150 uses SMC’s standard action, regulated to a higher level than what is found in some other SMC’s brands. The quality control is rigorous and well documented, resulting in an action that requires very little work from a dealer to render a responsive and satisfying experience for players.
The sound of the GS150 is round, slightly woody mid-range, a present but non-metallic or pushy bass, and a clear treble with typical sustain but far more complex overtones than average. The best musical comparison to this instrument would probably be a darkly voiced Kawai GL20. It dwarfs the GL10 and Yamaha GC1’s tonal output to the point where side-by-side comparisons feel comical. (Of course, the GL10’s action and treble sustain outperform that of the GS150, so with all things, it is a matter of priority).
The GS150 uses German Abel hammers, a rebuilder and manufacturer’s choice, and one of the premium OEM hammer manufacturers in the world. It produces a slightly darker, warmer, and more powerful sound than a typical Japanese hammer.
Johannes Seilers use spruce core soundboards with spruce layering on top – a technique formerly associated with lower cost pianos, but now found on instruments well into the $30,000 range by a number of makers. As Seiler has been able to find improved ways to increase resonance with the stiffer soundboards, their tuning stability and much better strength in varied climates have made them excellent choices for owners seeking lower-maintenance pianos without sacrificing musical performance.
The finishing quality and options available on Johannes Seiler pianos is amongst the most varied in the industry – with multiple plate colours, wood veneers, premium brass, and nickel hardware available to customers for attractive prices.
The piano uses a hardwood support structure and a beech rim.
