Hmm I was hoping for some kind of bi directional solution.

How do the pyramids work? How many come in a set? They just reflect the IR signal, right? I've heard of solutions which actually turn it into a radio signal which a receiver translates on the other end... That might be better, because my other problem is the floor plan dictates that the signal needs to travel around a corner... Like this:



There are speakers in both rooms. So it would look like I need a pyramid on the wall of my hallway between the two rooms... That's ugly, two of them for bi-directional would be even worse..

Anyone have any info on the ones that use radio frequencies (non-directional) rather than IR reflection?
