Just had a customer at work that I am building a boat tower for approach me about building him some speaker stands out of the same anodized pipe, sort of in the same style we use on boats. Should be fun. It's just kind of funny that it happens now, right about the same time I became reacquainted with audio.
I think a lot of it has to do with when people see that polished pipe, they try to think of a million other things to do with it, kind of like pvc.
