Time for the latest project. I'm working on a Dolby Atmos system for my living room. I didn't like where I would have to mount my surrounds because of no wall or a window in the way so I decided to make stands using 3" PVC pipe, toilet flanges, 3/4" plywood, and some 3/4” square dowels. The paint job isn't the best due to getting low on paint and had a wind issue. So it is what it is. Also had issues with the dowel measurements but made it work.
I filled each with play sand to weigh them down. Plus put some sliders on them to keep the wood from scratching the floor. Might switch to the rubber grippy ones if the speakers start moving around. To buy anything similar to this it would have cost me probably $150+. The cheaper ones on Amazon looked flimsy. I made it for like $60. I was going to put adjustable feet on them in case the floor is uneven, but didn't like how it looked. I'm pretty happy with how they turned out.
