Time has come to make a pair of speaker stands for my fronts, so as usual I started to look around for every possible solution. Saber saw and a drill - are the all instruments I have. And the very first idea which came to my head is to make these stands from concrete - I have plenty of it from the last basement fixes. Now, correct me if I'm wrong - concrete is very good sonicaly for the stands, the only issue it has is the weight. Here is a solution I'd like to implement to make it not so damn heavy: Materials: 12"x3' and 10"x3' quicktubes, 2'x2' mdf, some anchors and bolts, lightweight concrete, some black material/paint - everything should be well under $50 Cut both tubes in a half, center 10" inside of 12", stick some anchors in the ground. Fill the space between 12" and 10" tubes with the concrete, stick some more anchors and let it dry. So effectively it will be two short concrete pipes (didn't see any for sale) with the bolt mounts. Wrap in the material, mount bottom mdf plate and fill with some sand to push the weight down. Mount the upper plate. Ready to use. 12"-10"x18" pipe is pi(6^2-5^2)*18 = 622 cubic inches ~ 1/3 cubic foot, which should weigh about 25 lb each. I guess some birch can be used for the bottom plates instead of mdf, but the upper one should be done of mdf, right? Can the empty space inside of a concrete pipe somehow resonate? Any other comments?
