Currently in the middle of building some new speaker stands with my friend Zac. They are gonna be hefty to say the least. I have a 1ft sq. 1/4″ thick steel plate base welded to a 1.5″ wide 1/8″ thick 3.25′ tall steel pipe connecting the base to the 1/16″ thick steel top. As an added bonus I’m filling the pipe aprox. 1/4 full with sand. Talk about sturdy =D.
