Net Weight: 603 lbs (274 kg)

Braces

3 solid spruce with a volume of 1,196 cu. in. (19,597 cm³); Spruce provides tensile strength with less weight. Maple dowels fasten braces to rim & crossblock producing a single homogenous foundation upon which is built the tonal component. Note: Treble bell is not required in smaller grands of lesser tensions.

Overstrung; combination agraffe; Front AND rear duplex.
Tension: 33,823 lbs. (15,040 kg)

Ribs

Made from durable, resinous sugar pine to assure strong and constant support of string down-bearing on the soundboard; rib ends are hand-fitted.

Tuning Pins

Premium blued steel; rust-resistant, nickeled heads.

Strings

Treble: eleven whole & one-half sizes from high-tensile Swedish steel.
Bass: Swedish steel core wire wound with pure copper.

Hammers

Premium wool top felt and under felt; treated to resist insects and moisture. Compression-wired to maintain permanent shape. Hornbeam hammer moldings and shanks.

Dampers

Horizontal-cut premium wool for effective dampening with maple heads for endurance.

Keys

European spruce, individually weighed-off. Chip-proof, stain-resistant coverings for naturals; slip-proof, abraded ebonized sharps. Durable Linden wood buttons reinforce keys over balance rail, permitting maximum tonal power with every strike. Longest key: 19" (48.3 cm).

Keybed

Made from planks of quarter-sawn spruce. Horizontal and vertical birch planks present a vented system for humidity escapement. Crowned and reverse-crowned action frame gives a snug fit, intensifies key movement and prevents “slapping” during heavy playing. Large maple dowel ends provide a solid mount for adjustable brass touch-regulating screws. Thickness: 1¾” (4.45 cm).

Pedals

Heavy, solid brass. Soft, sustaining, and full sostenuto.
