The wooden rack hides a Titanium iso-skeleton, i.e. a rack within a rack. The horizontal Titanium tubes extend the full rack width underneath each tier, with a hole at each end through which the vertical titanium members pass with extremely tight tolerance. This inner Titanium skeleton is then coated with a custom adhesive to damp the entire structure after the compound has dried. The tubular Titanium stock is filled with various viscoelastic damping gels intended to tackle resonances at different frequencies. The gel filling beneath the bottom shelf thus is tuned specifically to address more bass frequencies since floorborne vibrations have a tendency to propagate up the iso-skeleton.
The isopods tie across the corners of the Craz rack. These isopods are filled with patented thermally reactive urethane hybrids which remain unaffected by temperature variations and are expected to work for 100 years. They are made to react to all manner of vibrational attacks by instantly auto-adapting their darometer (stiffness) index to generate the necessary counter motion which dissipates vibrational energy into heat. They self-restore to their original state for the next attack. These isopods are customized for the intended components to be supported and SRA will supply different ones when a customer upgrades equipment.
