Basement Floor Risers for Speakers or Furniture

My subwoofer sits on the floor in my basement, which is dry most of the time but sometimes gets some water during heavy rains. I was tired of having to deal with my subwoofer being wet on the bottom, so I designed these risers to keep it off of the floor a bit.

The black square is a piece of self adhesive rubber anti-slip material. It keeps the riser on the subwoofer but also insulates the riser from vibrations that might cause it to wander.

Here is the material used: https://smile.amazon.com/gp/product/B01K7JFXAA

These risers could be used on other basement furniture as well.
