Pianos out West proudly presents the extraordinary Wertheim Impedance Controlled Soundboard. Developed through extensive analysis and testing, our WF series pianos feature a meticulously designed Impedance Bar, a wood-shaping device that precisely controls the soundboard’s response to different notes and frequencies.
This ingenious design optimizes the size and shape of the soundboard, resulting in a seamless transition between the bass and tenor sections, eliminating unwanted resonances, and refining the piano’s overall tonal quality. So remarkable is this soundboard that our talented designer, Delwin D Fandrich, was granted a U.S. patent for it.
The exceptional benefit? A musically transparent bass-to-tenor transition that endows our pianos with a smooth and well-balanced timbre across the entire keyboard compass.
