I've always wanted a quadraphonic sound for the music. Two speakers in the front of the room and two in the back. Of course, you can't have wires running all over the place.
I thought, when I first saw the systems appear a few years ago, that there would be a lot on the market and everyone would be using them. What happened?
I Googled and found not much. Is there a reason this type of system hasn't caught on (like wireless mike systems)?
