BOM question

Just discovered the soundplane, looking forward to trying the DIY version. I have a question about the BOM. Specifically the dielectric:
12" by 12" by 1/16" thick Super-Resilient Silicone Foam Rubber

For that item at McMaster Carr there seems to be a firmness option of either firm or extra-firm. Which is the intended firmness for the soundplane?

After testing some 20 different elastomers, I am currently using a natural gum rubber foam that is even better. It's "Quick-Recovery Natural Gum Foam" in the McMaster catalog. I would try soft or extra-soft. I would also try 1/8" thick.

I'll see about revising the DIY info when I have time, please stay in touch and let me know about your project!

I'll also add what I tell everyone, I recommend you try a 1x1 or 2x2 version first, to make some mistakes and discover interesting things before wiring up a bigger device.
