are there power cables or batteries? Thanks
I bought the Rocketfish wireless rear speaker kit at BB for $99.99 and I love it. The unit plugs into the back wall behind my couch and you run the wires from it, not the reciever. I'm sure having it wired is the best way, but I have no complaints about my set up. It sounds great.
Some have batteries, most have power cables. None that I have heard sound good. I know it's a pain to wire speakers in but it's worth the time and effort (or cost if you have someone do it for you). Your going to have the speakers and setup for a long time, I presume. Do it right the first time and put the wires in.
