Alaskan Spruce Soundboards

Imported hardwood spruce soundboards require a long and drawn out production process.

WILH. STEINBERG grand pianos and upright pianos use soundboards that are made from the finest Alaskan spruce, which is best suited for producing pianos. The production process utilises a long, slow drying craft technique that involves 3 or more years of natural storage, followed by two manual drying stages and one to three months of static storage in order to guarantee the durability of the soundboard. The result is a highly transparent, highly textured sound reproduction.

Authorised production. Grand Piano And Upright Piano Series
(Yichang Jinbao Musical Instrument Manufacturing Co. Ltd. manufactured)
German authorised grand piano and upright piano series come with soundboards made with the finest Alaskan hardwood spruce. Soundboards are one of the most critical components of the piano.

All German built pianos use solidwood spruce soundboards made by Strunz and therefore posses a thick and grainy sound quality characteristic to German pianos, making them a highly sought after choice by practitioners and performers.

All WILH. STEINBERG pianos are made with rigorously selected Alaskan spruce soundboards
Features of solid wood soundboards.
  • Only through a mastery of humidity control, material selection, assembly and machining techniques, can the natural sound balance and musical qualities of a piano be maximised. The larger the piano, the more apparent the inconsistencies.
  • Different places of origin present differing raw material characteristics. For example, the German spruce, grown predominantly in Europe, when compared to North American spruce, posses a higher Young’s Modulus and a more traditional German timbre. In recent years, the exceptional sound stability and balance, and well defined tone of Alaskan hardwood spruce, has since made it a popular soundboard choice.
  • Recently, due to environmental considerations, many wood producing countries have seen dramatic limitations placed on their logging activities. As Alaskan hardwood spruce posses a uniquely rich and balanced tonality, a majority of the world’s producers of pianos have been gradually switching to this spruce for their soundboards, making the Alaskan variety one of the most widely used.

German Renner Hammers

Renner’s125 year history has not only resulted in the prominence of its name, but also the development and advancement of German piano making industry as well.
Throughout its history, Renner has been building on its artistic legacy, propelling the Renner name to international acclaim. WILH. STEINBERG pianos only use Renner hammers for the outstanding resonance they produce, providing a superior sound quality and long lasting durability that you can literally feel in your finger tips.

The spruce logs undergo a special and complicated process of drying and storage, before finally transforming into the magnificent components used in various instruments. This requires a careful and keen eye towards selecting the finest wood materials for this job. It has always been the objective of Strunz to create the finest sound quality possible. Each finished soundboard needs to pass through a series of quality checks. Only after successfully passing all the quality checks, will it then be used to fulfil the wishes of customers and adorned with the Strunz quality certification mark.

Features Of Renner Hammers
  • Its particular shape is specifically designed to harness every nuanced detail when making contact with the piano strings, liberating the piano’s natural and rich tones.
  • The meticulously chosen felt fabrics are made specially to order from felt companies like FFW. The felt material is carefully selected against the quality and accuracy of the fibre arrangement and the rate of damaged threads and material length, to ensure the best possible performance.
  • Even the moisture level of the felt is tightly monitored to alleviate deviations in hammer head production.
Renner uses a proprietary technique to produce hammer heads that are softer on the surface and harder at the centre, a critical parameter affecting the stability of the rich tones it can produce. These advantageous characteristics, satisfy the performers’ preferences for the tactile response of each key press as it delivers the fine, nuanced sounds generated. The bright, rich sounds produced become a direct representation of the performer’s every interpretation.

Internationally Renown Renner Action

WILH. STEINBERG Flagship S-Series Pianos

Actions made by Renner contain an average of 8,800 wood, felt and metal components. As Germany’s only piano action producer, each action produced incorporates the highest quality materials and the most exceptional craftsmanship. For over 100 years, Renner has preserved through the industry’s most challenging requirements and has produced only the very finest of piano actions.

The S series pianos enjoy the fruits of WILH. STEINBERG’s 125 year experience of exceptional piano making mastery. To date, it has produced over three million grand pianos and upright pianos that incorporate Renner hammers and actions. Each WILH. STEINBERG piano is guaranteed to offer a beautiful, precise sound quality that will faithfully reproduce each nuanced characteristic of the performer’s unique interpretation.

Unique advantages of the Renner Action
  • Renner actions can be highly customised to the specific needs of individual piano makers. In Europe, because many smaller piano makers were unable to make their own actions, piano action manufacture became a subindustry in itself. As Renner was able to very early on, master the intricacies of the action mechanism, it was able to design and produce actions that address the different needs of different customers, cementing its name as a leader in this field.
  • Over the years, Renner’s long term cooperation with piano makers has allowed it to listen and respond to its customer’s needs to create highly revered hammer actions. An essential component of the piano, the hammer action must finely balance the need for a light and fast attack movement, yet offer the correct amount of resistance. The intricate relationship between component lengths, resistance and torque are closely interrelated.
  • Renner has spent considerable time and energy in the perfection of its mechanism and has especially employed the use of advanced crafting and production techniques to ensure both the precision and accuracy of each action it produces. Wood, felt and leather materials are all precisely selected. Tools and wood processing methods are meticulously managed. This attention to detail has made the Renner name synonymous with exceptional quality and stability.

WILH. STEINBERG Pianos And Röslau Piano Strings

Each of the 230, lightweight, high performance, Röslau blue label piano strings, resonate with a charming and full bodied timbre.

While Röslau strings are considered expensive, their high performance and outstanding sound quality have made them a favourite with internationally renown piano makers. Its biggest feature, is that during tensile strength tests, compared to other strings in the same class, Röslau strings exhibit 10% greater tensile strength, making it less likely for them to deform or change properties due to the stresses of playing. One of the reasons is that the surface of each string is exceptionally smooth and its circumference is almost perfectly round. Therefore, these strings produce excellent sound with significantly less distortion.
