Has anybody tried this with good effects? I have some old metal pipes in the shed and they are quite thick but I know its not a simple case of joining bits of metal to wood. What is the best meterial to use for the base and top? I just feel like a bit of DIY and it will be a shame to let this metal to go to waste. My current speaker stands are too small as my listening position is a high up bed I need the stands need to be 100m at least my current ones are only 58cm so its very hard to get a sound stage from as the tweeters are too low down. They are also not very stable.
