Well, let me see; I am running from my receiver approximately 75' to our bedroom. This because I have a reel to reel tape recorder and this permits us to have some extended music. I do not know the model # of the speakers, but I believe they are originally designed for use with a computer. There is left, right, and a Sub woofer. I was of the impression that the tape record jack was an out put jack??? Look, I am 81, and my knowledge of electronics went out with the vacuum tube. I have no problems with the speaker end of the line, it is getting that signal out of the receiver, using what ever adapters are necessary. I wanted to use these speakers because, number one, I already had them, number 2, I can control the volume without running to the receiver. Any of you that are married know that man and women need different volume, and it is better to use the women's preference, more peaceful that way. Earle
