Joined Jul 5, Messages Likes Hmmm, it seems like nobody read the article and everyone just dismiss the result that clearly shows there are difference between each cables. Nobody says "There are no measurable differences between speaker cabels". Shure there are. But how much influence can this what you measure have on what you hear??? Donno, but this study is what you got. Just saying what's the point of dismissing it like the whole thread did. Measuring a cable at 3ghz to see differences in a cable thats used for max.
Thats why you see coax at your sat-tv and not on your speakers. The higher the freq. But thats not importent for a cable thats used at max. Thats like comparing the behavior of light with short wave. Yes both are EM waves. But they behave different. Couse the frequence of light is much higher. It's like measuring how good a copper cabel transfers light. Would that make sense for you? Jul 5, Did you read the article or did you just read the 1st figures?
I think It's measured at hz, 1k, 4k hz or something by glancing through it. Also 1st figure clearly says it was an experiment done back in , I assume this is a new article done in This is exactly what I am talking about going through the thread. Some weird comments just dismiss the article by not reading it. But maybe it was a 1. April joke and i didnt got. Thats possible?? Maybe you should read it first than come to a conclusion, and not saying others didnt read.
Stereophile article on speaker wire measurements. Thread starter orangejello Start date Jun 22, Prev 1 … Go to page. First Prev 6 of 7 Go to page. Jul 16, DonH56 said:. I don't have an iPhone but my Android does not do that. Not sure if your components need better RFI suppression or you need a different phone. That said, while I did exactly that experiment in the past, I have not tried it with my new processor. For the HT world, there is so much noise inside the box, that suppression pretty much has to be in there or nobody would buy the things Forum Donor.
We only get 3G at home. Cbdb2 Senior Member Jul 17, Doesn't happen to me much anymore since I got a 4G phone, but every 3G phone I ever had did it with pretty much every piece of audio electronics it was within 6 inches of. Jul 17, Cbdb2 said:. We are talking about cables. Does this hapen when your close to the speaker cable or close to the amp?
Ghz interference is fairley new to our world and many of the older electronics were never designed to deal with it. And there are ways. Yes, I know, you're not "hearing" RF, you're hearing rectified interference. Lorenzo74 Senior Member Dec 28, He is Stereophile. It is simply that when the tone bursts stopped, the speaker could not "stop" immediately.
The combination of the speaker driver inertia and stored energy in the capacitors and inductors generated a back EMF. And what were shown in the traces were the voltage drop across the speaker cable due to the back EMF when the back EMF is shunted through the output impedance of the amplifier. So what effects will this have on the sound radiated by the speaker?
The real test is to use either measure the sound pressure with an instrument mic, or use a laser vibrometer to measure the displace of the speaker diaphragm. If you do that, you will find out that the effects of the cables are either not measurable or totally negligible. They will be totally overwhelmed by the mechanical responses of the drivers. This are all elementary stuff. NTK said:.
View attachment View attachment View attachment I only suggested that you did not read the article because the 3ghz experiment had nothing to do with this experiment. So I'm unsure why you mentioned it in the first place, and it's placed in the first sentence of the article. So I think it makes a lot of sense to ask the question if you actually read the article or not.
My conclusion is the article clearly show the cable produce different waves, but like you said is it audible? I don't know. That's why I'm here. Now, instead of scientific discussion I found jokes based on false claim. Except one guy says wall absorption would make greater audible difference, which I agree. That's a lot of false claim for 3 pages of comments. I thought this is a science forum not I choose which data I want to believe forum.
What about cables apply to headphone then, it would take the wall factor out of the equation. Also, even if wall affect the sound greater than cable, it does not discredit this article a bit. It looks like you do not know the answer either, or maybe you do know the answer but without sharing the experiment to back it up. So what's the point to dismiss it? I think the general consensus in this forum is as long as cables are working and you are not running 10meter cable you are good to go.
However, this article clearly disapproves that. Now if you have paper or scientific experiment says it's not audible then please share it. Again, I thought this is a science forum not I choose which data I want to believe forum.
It's funny to call it an April fool joke when one really have nothing to show. Maybe that's the 4th July spirit instead? Get drunk and spit out gibberish lol. Now i never told the 3ghz experiment had to do with the later measurements. You can see i did the extract with the date of But it it is in this articel for what??? This articel is horribly unscientific it just gives you the impression it shows that you can hear speakercable differences and that there is a prove couse you can measure differences.
Shurly you can measure differences. You can easy measure different LCR of cabels but this tells nothing about how much you can hear it. Thats why i told they correlate venus phase with the taste of your cornflakes. And no in germany 4. Last edited: Jul 6, One has to question the writers of these articles.
They put up some theories, but never seem willing or able to make the final and crucial connections to what their practical implications are. Tertiary and quaternary effects were emphasized, but where are the discussions on their relative importance when compared to the primary and secondary effects? I'll go back to the Stereophile cable article and explain it with a little more details. The test setup is shown below.
