I asked a maintenance guy who fixes things around my house and he also knows a lot about receivers/speakers/etc. So, I asked him what mounts would I need to wall mount my speakers and he took a look at them and he told me I would need corner shelves that come out at least a foot away from the wall and he told me I could buy them from Home Depot. And he also said these corner shelves has brackets and he explained the direction the brackets are in but I do not know what he was saying. I also asked him if these comes in pairs. He said they ususally don't.
So, exactly what corner shelves is he talking about?
