using with ceiling speakers
I have a 7/1 system. I am moving next week and can not get the wires up my outside wall and into the ceiling so my question is, if i put the receiver end up in my attic (in the same room but in the attic) and plug it in up there and then into the speakers, will it work (with there being drywall between the transmitter and reciever)? I am seeing some responses that says it should go up to 100' and only loses about 20' for every wall and the 2 devices would be WELL within 80' of each other, more like 40'. Also, is there any reason for concern with having it plugged in up there?
