Question: What specifications are available in Speaker Wires?

Answer: These are available in different gauge (18, 16, 14, and 12). These products are high quality and have long product life. Most of the cables have pure copper strands under the flexible PVC coating. Typically sellers have cheaper options but there are made from aluminum coated copper. This is not the best solution as sound waves pass through these they disintegrates and fall off in powder form. It creates a break in the wires internally.
