STEINWAY & SONS Model B (6'10.5") semi-concert grand piano in polished ebony with Spirio
This magnificent model B grand piano is often referred to as "the perfect piano." It’s a wonderfully balanced and versatile piano that does extremely well in intimate settings, teaching studios, and mid-sized venues.
While Steinway adheres to the traditional values of craftsmanship, Steinway & Sons has also consistently led through innovation. The very earliest pianos crafted by Steinway were distinguished by their inventive features — many of which helped define the modern piano. Today, each Steinway piano is a summation of our commitment to innovation. Each incorporates over 125 patented features and processes, including our patented Diaphragmatic® soundboard, Accelerated Action® and Hexagrip® pinblock.
Ultimately, the pieces — massive and delicate — come together through the interweaving of the craft and technology until the instrument is complete. However it is not a Steinway until voicing gives it the special quality that makes it unique. Here, every subtle nuance is drawn out by balancing and adjusting the keys and shaping, hardening or softening each hammer. In the end, the new piano is transformed from more than 12,000 individual parts into an instrument… and from an instrument into a Steinway.
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 B general specifications:
STEINWAY & SONS Model B detailed specifications:
Rim
Made entirely from hard rock maple; 16 laminations; continuous bent, both inner & outer form one single rim; unequaled strength and stability.Thickness: 2 3/4" (6.99 cm)
Braces
4 solid spruce with a volume of 1,995 cu. In. (32,686cm3); Spruce provides tensile strength with less weight. Maple dowels fasten braces to rim producing a single homogenous foundation upon which is built the entire tonal component. A cast iron treble bell, affixed to rim's underside at treble bend, holds plate firmly in position by means of a steel bolt. The S & S iron wedge anchors brace ends securely to crossblock assuring permanent rim posture.
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: Continuous with treble. Maple doweled, glued, and screwed to soundboard.
Scale
Overstrung; combination agraffe; Front AND rear duplex. Tension: 39,047 lbs. (17,571 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: Twelve whole & one-half sizes from high-tensile Swedish steel. Bass: Swedish steel core wire wound with pure copper. Longest, Agraffe/bridge: 59 1/4" (151 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: 21" (53.3 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 made of birch, 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.
