The Stealth Edition is not merely a different color (black) top, but a separate, third constrained aluminum top layer which increases rigidity and damping over the standard Ultra Platform.

 

Technology

 

The Ultra consists of a multi-layered design (right) of varying density materials. But what's different about Symposium constrained-layer construction is that we have arranged the density of these layers in a specific order, from dense (metal top) to less dense, and then back again. The idea here is to gradually change density in steps, in the same direction, so that energy may penetrate more easily through adjacent layers. This unique but essentially simple design achieves optimal energy drainage from both the component side AND the support (bottom) side at the same time. This "dual direction" absorption provides effective isolation without eliminating the advantages of good energy drainage, and does it without introducing any mechanical "reactances" which are caused by materials which store and release energy, such as sorbothane and other rubber products. Instead of behaving like a reactive load, the design is more resistive, which means it is resonance-free, adding no colorations to the component's sonic "character" in attaining its goal of reducing noise and distortions in the components it treats.
