Ethifi - that 10 foot wall is really going to be a limiting factor in that room.
Even if it was a 50 x 10 ft room, you'd still have the 10' wall messing things up.
You will either have the speakers too close together on the 10 foot wall, or if you tried putting them on the 19' foot wall, they would have to be 5' out in the room to soundstage right, and then it would be an extreme nearfield.
So unfortunately in the context of audio, it is a small room. I'd stick with small stand-mounts.
