I am going to order some 12 Gauge speaker wire and have to deterine how much I will need. I read an article that the length of your wire should be all the same for each speaker. The farthest distance to my Back Surrounds will be aprox 35 ft....due to going along a couple of walls at floor level before getting to the speaker etc. My front 3 lets say would only need 7 ft of length. Based on this article I would need 35 ft x 7 for my speaker setup. IS This True ?.... Or can I go say 2 X 35 Ft Rear Surrounds....2 X 25 FT Side Surrounds.......and 3 X 7 Ft for the Front ( L,R & C ). Less speaker wire will save me money especially shipping costs from USA to Canada. The point of the Article was that the Audio Signal would reach all your speakers at the same time if the speaker wire was the same length,and therefor give a better sound overall.
