When you buy wired power cords and compare them to speaker wires, you may not see any difference. This is because power cables have a variety of functions, which causes them to share similar features with speaker cables. Electrical wires and speakers are both used to transmit signals (electrical or mechanical signals). Moreover, it is made of metal, uses insulation and connects the input to the output. With all these attributes, there is no real difference between a power cord and a speaker wire.
Speaker wires and power cords may look similar, but they are actually different. Speaker cables are only available in fiber versions, while power cables are available in fiber and solid versions. Speaker cable material is more or less the same as that used in ordinary cables. But, Unlike power cables, speaker cables are not designed to handle high voltages. The copper and aluminum strands may appear strong, but when exposed to high voltages, problems arise.
So Why Shouldn't You Use Power Cord As Speaker Cable?
This is because, the type of cable used can affect the sound quality you get from your speakers. Electrical cables with solid conductors are not only stiff, they can also damage connectors. Cable power cables can indeed be used for speaker cables because they are flexible and have better sound output than solid conductor power cables, but there are still limitations. The only problem is that they are not as good as speaker wires with very low voltage and frequency like speaker wires. The sound quality in your sound system may not be the same when you use a power cable instead of a speaker cable, but maybe not when connecting bulky sound equipment.
