The most advanced piano soundboard made today.
Maximized Resonance, incredible projection and sound Radiation

​My piano soundboards are made to take full advantage of many acoustic properties and thus are not copies, but improved versions of the originals.
My Unique Compression Crowning method takes advantage of internal forces creating a structure with a high stiffness to weight ratio, and allows for complete adjustments of acoustic driving points.

​I have made substantial improvements over the traditional methods. For instance....

The Naturally Bowed Rib.  I use and manufacture what i call the Naturally Bowed Rib.  For Longevity and Maximum strength, rib stock is aged on special designed racks made for warm air flow. Ribs with natural internal stresses will arch into a 60 radius arch. These are the proper rib stock to use which is then hand selected for the following processes. Further, the grain also is a true arch, which is stronger than a cut arched.

Engineering.  Each rib is computer engineered to determine the proper dimension, stiffness, and to create smoothness according to its scale position.
​
Acoustic Driving Points. Energy is transferred from the strings to the soundboard, thus driving points are created. If the driving points of the ribs and panel and bridges are not in proper alignment, then a MISMATCH occurs resulting in  ENERGY LOSS.

​                                EVERY MASS-PRODUCED PIANO I HAVE STUDIED, CONTAIN ACOUSTIC MISMATCHES.
 
After each Naturally Bowed rib is hand selected and properly sized, the driving point of each rib is adjusted so that it is in alignment with the bridge. This is done by adjusting  the scalloping on a specialized machine I invented.
Next the panel is made to the correct thickness, and graded according to the Golden Ratio as a layout pattern. Then the panel driving points are aligned to the rib driving points and the bridge. Again using specialized measuring equipment.


                             THE TONAL RESULTS ARE A DEEP FULL BASS, LONG SUSTAIN, AND CRYSTAL CLEAR TONES.
                                       Eliminating  associated problems of the break, and making voicing much much easier.



 Copying the Original Soundboard is a Mistake all others make.   It's interesting that two similar pieces of wood can have the same physical dimensions, but have different acoustical properties.  Bounce two on a concrete floor and often one will have a different pitch than the other.  
When rebuilders copy the physical dimensions of the old board, they're also copying the old boards mistakes. For instance, I found that many boards are just too heavy, which requires more energy to get it to move.

 An analysis of over 500 soundboards shows, massed produced piano makers didn't take the extra time needed to refine the compression soundboard to maximize its performance. Once they had a design the market accepted (good or bad) they just stayed with it.
There were many bad designs. For example, The diaphragmatic soundboard suffers from a panel that is too thin causing a deadness in the treble. 
Many other makers assumed stiffness is gained via mass, they made the panel too thick and the ribs too large, resulting in boards that are much too heavy. Often by three to five pounds.  This mistake is still being made by piano rebuilders today with their redesigns.   The whole purpose of using Spruce in the first place is because of all of the softwoods, it has the highest stiffness to weight ratio. This is not taken advantage of when adding too much mass to a design.
