so first of all I would like to apologize for the length of this post but please bear with me for this is not something that can be explained easily
the misconception:I've heard a lot of people say that if your speaker wire / sub wire are not match closely in length it can cause distortion and or cancellation of the sound waves...this is false to a point here's the truth
the first thing that needs to be known is at what speed does electricity travel the max speed of electricity is the speed of light or 186,000 miles per second. however since most electricity is traveling through wires it gets slow down by the resistance of said wires it can potentially be slow down to 60 percent the speed of light or 111, 000 miles per second.
now as an example I'm going to use a 50 Hertz shine wave for all the purposes of this formula. take that 111600 multiply it by 5280 and you get your electrical speed measured in feet per second (589, 240, 000)
now a 50 her tone means 50 cycles per second so each cycle is .02 of a second apart so for distortion to take place there must be a gap between the time each woofer reaches the peek and Valley of its cycle.so for the speakers to be out of phase completely there has to be a difference of .02
so if we know that our electrical current can flow through the wires at 589,248,000 feet per second that means that there would have to be 11784 more feet of wire on one side than the other. for the average person the length of extra wire going to one subwoofer or the other is just a foot or two so that makes no difference in sound quality or SPL!!!
one more quick example let's say I have 10 feet too much on one side that means my workers are only about 6 100 millions of a second out of fase... again sorry for the link I just wanted to once in for all the spell this myth so that way people are trying to cut every little centimeter of their wires thinking it's going to give a more dBreally all making both sets of wires perfectly even does is make you feel good at the end of the day so everything lines up it has no effect on performance whatsoever thank you for reading :-)
