STEINWAY & SONS MODEL M 5'7" Spirio Player Piano In Polished Ebony With Matching Bench

STEINWAY & SONS Model M (5'7") grand in classic satin ebony with Spirio

At 5' 7" (170 cm) in length, the Model M SPIRIO features a rich tone and responsive action that is found not only in a great many homes, but in many schools of music and conservatories as well. Called the “Medium” grand, there is nothing medium about the sound from this instrument. Complimentary iPad® included.

A Steinway grand piano takes nearly a year to create. Nothing is hurried. Even the carefully selected woods that make up the rims, top, soundboards, and actions cure for months in our yard, kilns, and conditioning rooms before they stabilize at a rigidly specified moisture content. The rim of the instruments consists of layers of hard rock maple and with our bell-quality, full cast-iron plate, withstands the enormous amount of tension exerted by the strings. The finest acoustic-quality spruce is fashioned into the delicate curve of the Diaphragmatic® soundboard, which tapers gently from the center to the edge, assuring the full, rich Steinway tone.

SPIRIO, a handcrafted STEINWAY like all others, is the next step in STEINWAY'S history of ceaseless improvement in its mission — declared by Henry E. Steinway, "to build the best piano possible" — and brings the unparalleled craftsmanship of the STEINWAY piano to your home coupled with cutting-edge technology and the peerless musicality of STEINWAY ARTISTS.

The STEINWAY & SONS SPIRIO is the world’s finest high resolution player piano. A masterpiece of artistry and engineering in your home, SPIRIO enables you to enjoy performances captured by great pianists — played with such nuance, power and passion that it is utterly indistinguishable from a live performance.

The STEINWAY SPIRIO remains a fully-functioning STEINWAY & SONS piano, with the same level of painstaking craftsmanship that goes into every single instrument STEINWAY produces. STEINWAY craftsmen seamlessly install SPIRIO at the time of the piano's manufacture, ensuring no alteration in the exterior beauty or performance you expect from STEINWAY. 

SPIRIO'S high resolution playback system uses propreitary software to measure hammer velocity (up to 1020 dynamic levels at a rate of up to 800 samples per second) and proportional pedaling - for both the damper pedal and soft pedal (up to 256 pedal positions at a rate of up to 100 samples per second). The Steinway & Sons Spirio player piano reveals the subtlety and passion of an artist’s original performance. Soft trills, delicate pedaling, and thundering fortissimos present no difficulty for Spirio and are reproduced with unparalleled accuracy, smoothly and precisely realising the pianist’s entire range of motion and emotion.

The powerful STEINWAY sound, the ever-expanding content library and high resolution technology are all easily accessible thorugh the STEINWAY SPIRIO app - an intuitive and easy-to-use interface.

STEINWAY & SONS Model M detailed specifications:

Rim
Made entirely from hard rock maple; 10 laminations; continuous bent, both inner & outer form one single rim; unequaled strength and stability.Thickness: 2 1/4" (5.72 cm)

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

Pinblock
Hexagrip patented design; 7 laminations of quartered hardrock maple stock. Grain symmetrically distributed at successive angles of 45°, 90°, employing grain direction uniformly around the circumference of the tuning pin to provide the ultimate in pin grippage. As a result of this exclusive design, the tuning pin has smoother movement under torque, a more uniform retaining action for solid setting, and a piano which will hold its tuning longer.

Soundboard
Created like the soundboard of violins to give a free and even response throughout the entire scale, it is so constructed as to be 8 mm thick in the center and tapered to 5 mm as it approaches the rim and outer case before being DOUBLE CROWNED. This design permits complete freedom of movement, while acting as a homogenous unit to displace a greater amount of air, thereby creating a richer and more lasting tonal response. Close-grained, quarter-sawn Sitka spruce, a wood having unusual stability and vibrance under stress and vibration, is used exclusively for the soundboard.

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 into their mounting surfaces virtually locking in the important soundboard crown.

Bridges
Treble: Hard rock maple vertical laminations capped with solid hard rock maple; planed to prescribed height, graphite coated, drilled, and notched by hand for precise individual string bearing. Design defies splitting. Bass: Solid rock maple mounted to cantilevered and splined base. Maple doweled, glued, and screwed to soundboard.

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

Plate
Sturdy gray iron; filled, CNC-milled, and sealed; bronzed and lacquered.

Tuning Pins
Premium blued steel with 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. Longest, Agraffe/bridge: 49 1/4" (125 cm)

Hammers
Premium wool top felt over premium wool under felt; treated to resist insects and moisture. Compression-wired to retain permanent shape. Hard rock maple hammer moldings and shanks.

Dampers
Horizontal-cut premium wool for effective dampening. Maple heads for endurance.

Action
White, quarter-sawn maple parts are bushed with specially treated wool action cloth for freedom from friction. Parts are anchored in hard maple dowels housed in inflexible seamless brass tubing to assure precise & stable regulation. Exclusive single, combination phosphor bronze repetition & fly spring provides constant, crisp touch response. Specially designed to respond 14% faster fortissimo & 6% faster pianissimo by using an exclusive combination of half-round balance rail bearings and strategically placed key leads.

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

Keybed
Made from planks of stable, quarter-sawn spruce. Horizontal planks are freely mortised together, while their ends are permanently mortised into vertical planks, presenting a vented system for humidity escapement while allowing for necessary expansion and contraction. Front center is crowned contrasting the reverse-crowned action frame for snug fit. This design intensifies key movement and prevents "slapping" during heavy playing. Large maple dowel ends provide a solid mount for adjustable brass touch-regulating screws. Thickness: 1 3/4" (4.45 cm)

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