Dakkon, that's very similar to the rack that the previous owners had in that location. The wires are actually intended to be on the other side, where multi room speakers are sourced. I of course relocated the entire house's AV components to a downstairs closet. So I don't have any need for a rack up here.

I'm a DIY type (fished all the wires myself, for instance) but I have no confidence whatsoever in my ability to design or weld something. Stands are cheap enough that I'd buy one.

I was thinking that shelves mounted to the side wall would get the speakers positioned well. But I don't think there's any way to do that without it looking goofy. Like the wall has ears or something.
