Plinth Builder's Gallery
Wikipedia. plinth: " A plinth in architecture is the platform or base upon which a column, pedestal, statue, monument, or structure rests."
Webster's Dictionary Definition. Plinth: "A slab-like member beneath a column or pier. "
The term "plinth" is also used to describe the supporting structure for the spinning platter of a record player. That is how the term is intended here.
This gallery offers images of both commercial and amateur (diy) plinths that have been submitted by their authors.
Note: The webmaster welcomes submissions from all parties. There will be discrimination made as to the level of craftsmanship, design and aesthetic qualities prior to acceptance of all submissions.

More definitions of terms:
Methods of acoustic dampening within a structure.
(CLD) Constrained Layer Damping systems are usually used for very stiff structures. A sandwich is formed by laminating the base layer to the damping layer and then adding a third constraining layer. When the system flexes during vibration, shear strains develop in the damping layer. Energy is lost through shear deformation rather than extension of the material.
Free-Layer or extension damping: A material is simply attached with a strong bonding agent or alternately may be troweled on in the case of tar-like damping materials. Resonant energy is dissipated as a result of extension and compression of the damping material under flexural stress of the base material.
Vibration Isolation: This method reduces the transmission of vibrational energy from one system to another. Common isolators are steel springs, rubber pads or bellows.
