Inheriting a Craftsman Spirit

Along with along period of edification and baptism, Kayserburg piano has become asymbol of excellent lifestyle and high-aulity pursuit.

Kayserburg Piano Voices, Resonating in the World

Kayserburg is the latest professional high-end piano brand launched by Pearl River Piano Group, an the pianos are created by Pearl River Piano Group's elite team joined with the European technical team.German Renner hammers are hand shaped to bring the finest tone from the German Roslau string wire, solid maple caped bridge and European Siberian solid Spruce hand selected soundboard.

To ensure the perfect and outstanding acountic quality and performance, Kayserburg pianos select the most excellent materials; adopt the European international high-end piano processing technology and manufacture standards.

Introducing The Kayserburg |Étoile Collection of Exotic Woods

Named for the French word for ‘star’ (pronounced eiˈtwal), the Kayserburg Étoile Collection brings forward the ultimate expression of turning rare wood’s natural luster, color, and patterns that change from every angle into heavenly beauty.

Of the more than 90,000 species of hardwoods in the world, only about 100 are used in the fancy veneer industry. For the Kayserburg Étoile Collection only the most impactful have been selected; whether it’s East Indian Rosewood, which is considered one of the most beautiful lumbers in the world that is found in many Asian antiques, or Ziricote, an exotic wood native to the Central American that ranges from reddish-brown to dark brown with unusual streaks of pale-yellow sapwood.

Kayserburg pianos generate resonace with music, bring unlimited music enjoyment to performers, and satiffy the pursuit of perfect quality and excellent lifestyle.

Hammers

In creating the finest pianos in the world, Kayserburg developed the PR2.0 hammer design using imported German felt that is formed over select hardwood cores and then fastened to the cores with t-shaped steel wires for the maximum resilience and structural integrity. Improved hammer shanks adopt the grand piano concept for the ultimate balancing while each hammer requires a minimum of five inspections to earn quality control certification. 

Acclimatized For The World

Before and after drying in our state-of-the-art kilns, woods are expertly cured to specific moisture contents, which reduces the natural tendency for wood to swell and contract with humidity fluctuation. In crafting each Kayserburg piano, humidity and temperature levels are strictly controlled by dehumidifier and air-conditioning systems to ensure a consistent environment throughout the production line.

Double Action Rest Rail

To lower the volume and sustain, the hammer rest rail rotates to reduce the hammer strike distance. The Kayserburg vertical pianos action has been doubled from a single rest rail to give the hammer shank more accuracy and to offer more accurate control for both volume and sustain.

Jack - Limited Rail

To complement the Double Action Rest Rail, Kayserburg has added a Limited Rail device for rapid reset of the Jack during the playing of high-speed passages that require continuous movement of the hammers, resulting in an enriched performance.                       

Kayserburg Wet Sand Cast Plates

The plate supports the incredible tension placed on the instrument by its strings. Like the world’s finest pianos, Kayserburg plates are made with the highest-quality pig iron formed in wet sand molds, then CNC machined and fully finished. Unlike vacuum processed plates, wet sand cast plates are stronger and do not produce undesirable harmonic feedback.

Bridges

To accurately transmit the vibration of each string to the soundboard, the bridge must be extremely strong, rigid, and resonant. Kayserburg pianos feature vertically laminated,  Beech and Rosewood bridges, for increased rigidity, with a solid beech cap. The bridge is glued, dowelled and screwed to the soundboard.

Silver Plated Regulating Front Caster

The height of the front caster can be individually adjusted according to the condition of where they are placed, ensuring the piano is always perfectly stable and level.

Asymmetric Back Post Structure

Because of the difference in string tension, Kayserburg vertical pianos have an unequal distance, asymmetric back post structure. Scientifically designed to balance the bearing capacity of each sound section, the structure provides added stability and strength. Kayserburg verticals have an inner rim of solid beech and solid spruce backposts for a sound that’s warm, clean, and distinct.

Ribs

Select quarter-sawn spruce ribs are graduated in width and thickness, and feathered for flexibility and frequency response, are glued and hand doweled to the soundboard and then mortised into the rim.

Keys

The keys on all Kayserburg pianos are made of solid, straight-grained, spruce for a light key with superior strength and accurate transfer of the pianist’s intentions to the hammer. Genuine ebony wood is used for sharps, while white keys are covered in Ivolan®, an eco-friendly ivory substitute with a gentle gripping surface for a more natural feel and easier control. Each key is individually weighted for an overall even touch. Where the balance rail pin supports the key, a solid hardwood key button and insert ensure stability under the most stressful playing. All pins are solid brass for stability and noise-free sound production. To resist warpage or movement, the keybed is constructed with solid European spruce in a butcher block configuration.

Rim & Beam Construction

Kayserburg grand piano outer rims are made from maple and inner rims are made from beech. The beams are crafted from the finest quality solid European Spruce and are individually attached to the rim with mortise and dowels, not screws, for structural integrity that will last decades. Many of the world’s finest grand piano rims are made from maple and beech, dense hardwoods that allow for warmer, richer tone with longer sustain.

Tapered Soundboards

For greater dynamic range and improved sustain, all Kayserburg pianos have tapered soundboards crafted entirely of tight-grained, European quarter-sawn, solid spruce from remote regions as varied as Siberia to the mountains of Central Europe are the hallmark of Kayserburg pianos. Each soundboard is given years of special seasoning, then handcrafted to ensure a precise crown (natural bowing). 

Cut-Thread Tuning Pins

Rather than stamping the pin thread, nickel-plated and cut-thread tuning pins offer more precision and control for longer lasting tuning. The pins are set into a block made of cross-laminated, quarter sawn maple or beech for maximum resistance on the tuning pin thread.

Strings

Kayserburg uses only the best: Röslau strings from Germany, with solid surgical grade steel treble strings and solid copper hand-wound bass strings.
