A Light Rigid plinth with minimal footprint that maximizes sound quality.
It starts out as an idea, then morphs into a sketch, or many sketches, like below:


Once the 3D cad model has been evaluated for interference of fit and many other considerations, material gets cut as below:

With sn 13943 clamped into it, the listening began.
Another view, the underside:

Can be used with or without mushrooms. I've tested it without.
For more images to evaluate every corner, inside, underneath and out, please see the info link at top of this page.
Design goals:
light/rigid philosophy applied to a Td124
Minimal foot print without sacrificing sound quality.
My impressions; design goals met. Now I'm moving on to another similar design that implements the light/rigid ideas but with a slightly different shape. As I continue to refine my ideas on TD124 plinth design, I will make available for sale my design prototypes, like this one.
I sell this as a demo unit. Thoroughly evaluated with minimal wear and tear.
Thanks for looking.
