Every aspect of it&#039;s core design is focused towards creating the best sound possible. With a massive soundboard featuring Klavins&#039; unique double layer design and bass strings that extend nearly 4000mm in length, the 450i features none of the compromises inherent to all other concert grand pianos. The result is a sound that is uniquely rich and clear across the entire range. The steel frame (carrying twenty tons of force generated by the 246 total strings) provides a simple and graceful shape to the 450i while also providing an ample platform for further customization on form and material to fit the space the piano will enter. The piano is also designed to be able to be integrated directly to the architecture of its intended home, much like a organ in a concert hall. This takes its efficient footprint when compared to typical full-sized concert grand and extends it even further by making the 450i part of the building itself. The designing of the Model 450i was a process in seeking new heights in what is possible in a concert piano. Rather than relying on the 100-year old conventions that have arrested the progression of the piano as an instrument, the 450i, like all Klavins Pianos, was conceived with the conviction that there are truly infinite new possibilities in instrument design.
