Length: 156 cm (5′ 1½”)
Width: 151 cm (59¾”)
Height: 102 cm (40″)
Net Weight: 311 kg (684 lb)
BRACES
Radiating braces solidify the piano’s structure. Their triangular layout provides more support than parallel designs. This rigid system improves tuning stability and soundboard crown retention and lengthens piano life. 2 braces + 1 treble.
SCALE
Overstrung; a combination of agraffe, with front and rear duplex. Rescaled bass and treble for lower tension scale for increased sustain, better tone clarity, and deeper clearer bass. 17,565 kg (38,684 lb) tension.
RIBS
Made from durable spruce to assure strong and constant support of the strings bearing down on the soundboard. Ribs are fully let-in to the inner rim to support the important soundboard crown and prevent the piano from losing its tone. Number of ribs: 10
BRIDGE
Treble: Vertically laminated (alternating maple and mahogany) with a solid maple cap, curved to fit the crown of the soundboard. Bass: Solid maple mounted to cantilevered base.
STRINGS
Treble: Highest grade steel (in half size increments). Number of sizes: 13. Lowest tenor note: 33. Mapes Bass Strings: Steel core wire wound with solid copper. Made by Mapes in Tennessee, U.S.A. Note 1 speaking length: 114.2 cm (45″).
HAMMERS
Premium wool topfelt over premium wool underfelt. Weight of topfelt: 9.5 kg (20.9 lb). Compression-wired to retain permanent shape. Mahogany mouldings. Tapered hornbeam hammershanks. Computer-designed pear-shaped hammers result in a superior tone, increased durability and greater voicing ability.
ACTION
Solid maple and hornbeam(all wood, no plastic) for all moving parts. Steinway profile-shaped flanges, extruded aluminium action rails for increased stability and less frequent regulation. Steinway action geometry provides a superior touch.
KEYS
Genuine spruce, individually balanced and weighted. Synthetic ivory and ebony key covers. New synthetic ebony has ebony-like surface texture and appearance that absorbs perspiration from the fingers. The fine synthetic ivory of the white keys has the same properties of friction, porosity, conductivity, and appearance as ivory.
PLATE
Cast from grey iron, bronze-painted and lacquered. Vacuum cast.
PEDALS
Heavy solid brass castings. Soft, full sostenuto and damper (sustaining).
ARCHITECTURE
Classic case design. Coved toplid and keyslip, square arm shape with matching square fallboard shape, and wall cornice detail are all classic and beautiful.
OTHER
Fallboard: Soft fall fallboard.
Casters: Heavy-duty double-wheel solid brass casters.
Locks: Fallboard.
Prop Sticks: Double top prop sticks.
Bench: artist, adjustable bench (cushion, adjustable height) for all ebony finish pianos.
Black Felts for Plate, under Fallboard, and around Pedals on Lyre.
