Any suggestions -speaker stands for audioengine 5+

this system is ipad source through wireless DAC. Outside patio area.
Are they outdoor speakers? I have some and wouldn't use them outside.

I honestly can't remember if they have threaded holes in the bottom for stands, but I don't think so. Maybe a shelf with straps to hold them?
make them from PVC pipes and MDF shelves cheap.
I live in Central Florida and take them in during the humid weather. They are in protected covered patio area. They do have threaded holes.
