I am helping my friend rewire his old house with cat5e and rg6. My friend wanted to add surround sound to his game room and speakers throughout the house for music. I told him the only speakers I have installed would be paging speakers, so asking around another friend told him to use cat5 cable. I have used cat5 for paging speakers but I have never heard or cannot imagine using it for wall speakers with high end components. If someone has heard of this please tell me the good and the bad
