(Also not that I'm not looking at other things like phase and resistance of the cable and things like that. and what about a difference in length between the wire running to the woofer and the wire running to the tweeter? Oh man. This should clearly be a trigger to note that his logic is wrong: a smaller difference in cable length, can never lead to having to compensate with a larger distance between speakers.Īnd what about the wire used inside the speaker? If there's a difference between two speakers, I cannot compensate. Wow! that's even a larger difference than in the youtube video for a difference of 1 inch. Let's do the same math as in the youtube video but instead of 1 inch we take 1/1000 of an inch. And I was quite successful! I measured the difference between the two cables, and it is only 1/1000 of an inch! Impressive wire cutting, right? Now let's see how much I have to move my speaker to compensate for this 1/1000" difference. I bought the recommended brand of loudspeaker wire and did my best to cut it into two exactly equal halves. Let's say I'm totally convinced by the video. Let's approach it from a yet different point of view (including math ).
(The calculation I did in my previous post for a difference in cable length of 1 inch.) and not larger like the conclusion of the youtube video. This means that if you want to compensate for extra cable length, you would have to move your speaker back a certain distance that is smaller then the difference in cable length.
Because the speed of sound is slower, in this same amount of time the traveled distance by the sound in the air is smaller. Since the speeds of electrons is very high, this will cost only a very small amount of time. The extra length the electrons have to travel in one cable will cost a certain amount of extra time. Electrons travel at very high speed through the cable sound travels at relatively (compared to the speed of light) slow speed through the air. Let me try explaining it differently without doing any calculation with these large numbers. And that's what I'm saying: his reasoning is flawed. You can do all your divisions correctly, but if you should have been multiplying, you will still end up with the wrong answer.
I'm not doubting math at all, I'm just doubting the way the youtuber applies math.
