Ordinary RG 59/U type video coax does NOT make good speaker cable. Its centre conductor is equivalent to about 22AWG wire, and will have the same loss of signal over distance as el-cheapo speaker wire. Video coax is designed for one thing: If you feed a signal into one end of it from a source with an impedance of 75 ohms, and you terminate the far end of the coax with 75 ohms, the signal can be sent over a considerable distance and arrive at the other end relatively undistorted - no echoes. It probably has higher capacitance per foot than ordinary interconnecting cable, and higher resistance than speaker cable, so it does both jobs more poorly than cable designed for that task.
