Amazingly Priced IMMACULATE Concert Grand C-3
Today's C Series grands also incorporate all of the quality construction features found in prior C Series models.
I purchased this in 2007 from it's original owner and now am needing more space. It has been recently appraised at $22K. Today's new price is around $36K.
As with the C-series, rims are formed from layers of select woods, laminated into shape in special presses, then seasoned to allow the wood to stabilize. Sturdy back posts are joined in a radial configuration and fitted to the rim using exceptionally strong and stable dovetail joints, enhancing both the pianos durability and the integrity of the acoustic chamber.
Iron plates, the internal frame of the piano, are cast in a vacuum molding process that virtually eliminates flaws and imperfections, then attached with an adjustable mounting system that allows precise control over string downbearing – critical for the best tonal performance. A metal tone collector connects the back posts to the plate, reflecting sound energy back through the case for a fuller, more sustained resonance.
Soundboards are crafted from select clear spruce and cured in a proprietary process that ensures a durable, natural crown. This is further reinforced with full-length spruce ribs, securely mortised and glued into the inner rim. Bridges are formed from fine-grained hardwoods chosen for optimal sound transmission, and precisely notched and pinned to carry the strings.
Produced from special steel and pure copper wire, strings are installed with the aid of special equipment for consistent, even tensioning. Duplex scaling, which tunes non-'speaking' lengths of the strings, enriches primary tones with complementary harmonics.
Pinblocks, where the tuning pins are set, are made from layers of dense hardwoods, bonded in a process that seals against fluctuations in humidity. The pins themselves have lathe-cut, rather than roll-pressed, threads, to ensure the best grip in the pinblock, and are nickel plated to resist corrosion. Together with the integrity of structural components, these features help to give Yamaha pianos an exceptionally high level of tuning stability, assuring better sound between tunings and requiring minimal regular maintenance.
