For sale the Symposium Ultra Platform in
optional "Stealth Edition" black top edition (with 3rd laminated
black top laminated aluminum layer) in excellent condition 19x18 with
“Symposium” labels on two sides. Comes
with original box, packaging, manuals, and double box.
Two platforms available for sale
for per platform
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.
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.
