Hi Romy and Guy

I've been checking out various plinths for my new DIY project. The project's base is a Technics Sp-10mk3 motor unit.

When you say a materials 'frustration' I guess you mean the choice of alloy and the quality of the casting? Inproper casting could results in higher stresses or varying material 'frustration'.

I was looking into resonances of materials. Some choices such as slate could reinforce the bass frequencies as it resonates at a slightly lower frequency than granite (~100hz). CLD type plinths may have a higher resonance still.

My thoughts were that the choice of materials and quality of casting allowed the design team to more accurately control the resonance frequency of the finished product.

Regards

Richard
