Welcome dastro
If you click on my signature it will take you to pictures in different places of my threads with wood and aluminum tubing stands I built.
You will also find a thread on building new frames that raised up the panel to a height that you would listen to the center of the panel. Yes, my frames look strangely like Neoliths. I built mine before the Neolith existed but they not doubt had their design before I created mine.
