Technical Specifications

Rim/Backframe
Mahogany foot-piece soundboard lining and backboard. Specially-designed grand-type mahogany closing rim; unequaled vertical strength and stability and improved acoustics. Backposts have staggered spacing to enhance tone and provide support where needed.

Braces/Posts
Full-length laminated mahogany posts assure that the backframe will remain straight and consistent and tuning will remain stable. Mahogany fill-blocks between posts at the top and bottom of the backframe, capped with a mahogany backboard for positive vertical alignment. Solid filler blocks (no hollow spots). 5 posts. Total cross sectional area: 450 cm2 (69.8 in2). Thickness of post: 9 cm (3½”). Width of post: 10 cm (4″).

Pinblock
Octagrip™ pinblock made of 11 layers of hard rock maple – glued in different grain angles of 60 degrees – affording the tuning pins greater stability under tension and enabling the piano to stay in tune longer.

Soundboard
Close and straight-grain solid (not laminated) Sitka spruce. Minimum 3 annual growth rings per cm (minimum 8 per inch). Tapered from treble to bass, to provide a rich tone in the bass, and a brilliant and crisp tone in the treble, creating a well-balanced and lasting tonal response. Tapered from 9 mm to 7 mm dual tapered. Vibrating area: 1.07 m2 (1,659 in2). Closing rim evens out the soundboard’s response to all frequencies, eliminating “hot” spots. Emulates shape of grand soundboard.

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 liner to support the important soundboard crown and prevent the piano from losing its tone. Number of ribs: 11

Bridges
Treble: Solid maple, curved to fit the crown of the soundboard. Bass: Solid maple mounted to cantilevered base. Doweled, glued, and screwed to soundboard. One continuous base and treble bridge.

Scale
Overstrung: Lower tension scale for longer sustaining tone and longer life of the whole piano. 16,727 kg (36,877 lb) tension.

Plate
Cast from grey iron, bronze-painted and lacquered. Vacuum cast.
Tuning Pins Nickel-plated steel, cut threaded.

Strings
Treble: Highest grade steel (in half size increments). Number of sizes: 12. Lowest tenor note: 28. Bass: Steel core wire wound with solid copper. Number 1 speaking length: 117.3 cm (46.2″)

Hammers
Premium wool topfelt over premium wool underfelt. Weight of topfelt: 9.4 kg (20.8 lb). Compression-wired to retain permanent shape. Mahogany moldings. Hammer-shanks from select resilient maple or horn-beam. Computer-designed pear-shaped hammers with reinforced shoulders result in superior tone, increased durability and greater voicing ability.

Action
Solid maple (all wood, no plastic) for all moving parts. Extruded aluminum action rails for increased stability and less frequent regulation. Dependable direct-blow design.

Keys
Genuine spruce, individually balanced and weighted. Synthetic ivory and ebony key covers. Length of key: 36.8 cm (14.5″).

Keybed
Made from laminated hardwood. Strong, rugged construction provides a solid mount for the keyframe and action allowing for precise and prolonged action regulation. Keybed thickness is 42 mm.

Keyframe
Spruce with hardwood inserts in the balance rail and front rail for added stability.

Pedals
Soft (half-blow), muffler, and sustaining (damper) pedals.

Other
Music desk: Professional music desk. Two-position upper panel for tone escapement and solid music support. Fallboard: Soft fall fallboard. Casters: Solid brass casters. Prop Sticks: Top prop sticks. Bench: Matching wood-top bench.
