I just bought a set of klipsch promedia 4.1's (w/tornado 5.1 decoder) and I need a way to mount the rear satellites. The catch? I'm in a dorm room and I can't take up any floor space by using conventional mounting "stands". So I either will mount the speakers from the ceiling, or use an odd approach I saw once in a display stand for a Bose 5.1 system in a tweeter shop in natick, massachusettes.
It looked like this: (bow down to my mad mspaint skillz lol)

It attaches to the front wall and then extends back behind the listener and the two rear satellites are held at about ear-level. I wanted to keep the satellites at ear level since the tweeter horn in the klipsch satellites tends to project relatively horizontally planar.
I wanted to know if anyone knew where to buy one of these, what it is called, or how to fabricate it. Any help would be greatly appreciated.
