The Symposium Ultra Platform evolved from our first product, the Super Platform, and was created in an attempt to push the performance limits for a solid equipment platform further than had previously been possible. Experiments and listening tests in many different types of systems indicated that those aspects of the Super which could directly benefit lay in the thickness of the foam center section (which serves as a "heat sink" that converts mechanical energy to heat) and in additional constrain layering of the critical top layer. Also, a new, larger coupler was made which would provide more surface area contact between the Ultra's top and the equipment chassis.
The Ultra retains the following features of Symposium energy absorption construction:
Ordered constrained-layer construction
Superior energy dissipation with low reflection back to the component
Solid platform with no "bounce"
No leveling problems.
No leakage problems.
Virtually no weight limit.
Zero interaction problems with tuned suspensions of turntables.
Performance independent of its support structure
Ideal interface for Rollerblocks, cones, and most "footer devices."
Compatible on top of low frequency isolation devices
