The INGREDIENTS
SorbothaneSorbothane® is one of bFly-audio's choice absorption materials. Sorbothane® is a proprietary, visco-elastic polymer. Visco-elastic means that a material exhibits properties of both liquids (viscous solutions) and solids (elastic materials).
Sorbothane® combines shock absorption, good memory, vibration isolation and vibration damping characteristics. In addition, Sorbothane® is a very effective acoustic damper and absorber. While many materials exhibit one of these characteristics, Sorbothane® combines all of them in a stable material with a long fatigue life. Sorbothane® has a low creep rate compared to other polymers (rubber, neoprene, silicone, etc.) Sorbothane® has a superior damping coefficient, over a very wide temperature range, compared to any other polymer. Unlike fluid-based shock absorbers or foam products, Sorbothane® absorbs shock efficiently for millions of cycles. Finally, Sorbothane® eliminates the need for metal springs to return the system to its equilibrium position after absorbing a shock. |
The "SECRET Blend"bFly-audio call it "MLA" - Multi-Layer Adjustment - carefully selected layers of different absorption materials of different thicknesses and orientations. Materials such as Sorbothane®, cork and natural rubber are separated by a non-absorptive aluminium layer.
Each absorption layer provides filtering of different vibration frequency ranges. In addition the orientation is critical - for instance the bamboo used in the PowerBASE is made up of three laminated layers, each counter-rotated by 90° for optimum absorption. The end result is an improved cumulative vibration control, compared to the traditional use of just one or two materials. 
PROfessional foot - cross section
The PowerBase together with the PROfessional feet, represents the pinnacle of the practical expertise gained by bFly-audio over the past decade, consisting of a total of 11 different absorption layers.
