OMG If You Coil Your Speaker Cable You're Gonna Lose Fidelity?!?

What happens if you coil excessive speaker cable on the floor? Will it act like an inductor? Will you lose performance or fidelity? In this video I demonstrate through measurements exactly what happens and determine whether or not it should be a concern to any audiophile.

Finally, someone who is putting REAL SCIENCE behind speaker cables! Thankyou Audioholics!

[@timeWaster76]

Wouldn't you know after 2 years, 69K views and only 3K likes . People don't like hearing the truth ... I worked i a physics lab we did similar test but more testing on sound coming off the speaker we used hi end research gear. and NADA .... when we measures at the cables at connectors. how tight the binding posters were made a difference but so far out from audio range and human hearing ... well unless the connections were loose that made a difference anyone could hear.. like cracking.

[@richarddortch6122]

More and more I find myself making the same statement to my audio buddies. Does it make a difference? Yes Can you measure the difference? Yes Can you hear those differences? Most likely not Do you want to spend money chasing that kind of difference? Most Likely Not

[@TofumanFC3S]

I have noticed that room size and shape make so much more of a difference that the coil issue is just silly.

[@adamsonlinearrayspeakersha87]

Hello

[@nihilityjoey]

The same can be said for any audio equipment then. Why spend 10 grand on a set of speakers if you can get a set with the same frequency response, same amount of speakers? Especially if the room is what will give you the most control over the overall sound? Is the change in wave guide the game changer? I mean you can measure the difference the wave guide has on the crossover point can you not? Can the majority of people hear the difference? And is that difference worth another 8 grand? The amp might be more efficient at running your speakers, can you HEAR the difference? I find it interesting how the audiophiles get a lot of flack, yet even at the other scale the differences in the tech you get from each price jump is just as "emotionally driven" when choices are made. Why did gene chose the speakers and amps he did given what else is comparable out there? I mean sure he can maybe measure the differences, but can he hear then? And is the difference worth the extra in price, and if not WHY make the choice. There is a measurable difference when the cable was rolled up, in that respect no one was wrong. Can the difference be heard? Well again, I'll refer you to what I've just written.

[@richarddortch6122]

@@nihilityjoey You pretty much proved my point. Just in a LOT more words. Unless you have money burning a hole in your pocket, just buy what sounds good to you that is reasonably within your budget. Room setup is free, treatment costs a bit. I would argue that the extra 8k might be better spent on room treatment than the speakers. You'd have measurable AND audible improvement if done right.

I was recently wondering about exactly this, not just for speaker cables but for any cable. Thanks for doing the measurements and showing the calculations. Very helpful.

[@bighands69]

Coiling cables only become an issue when there is a larger load, potential temperature increases and when the cable has a very long distance to cover. In building electrical systems it can become an issue when there is something like an electric shower or motor being driven with a cable covering hundreds of feet. So how they overcome issues with electrical cables they use larger cross sectional areas to drive impedance down so in other words they use a thicker cable.

[@08ExigeS240]

How about do some measurements of the effect of having power cables next to audio cables? Balanced and unbalanced. Thanks!

[@Jcan4u]

i have seen the effects of this in car audio and if not properly separeated or installed with supressors that changes the fedlity of your equipment, the engine noise comes through so yes that you would be nice to know

[@08ExigeS240]

To my understanding it’s best practice to keep power cables separated to reduce the chance of noise interference but of course with multi channel processors, multiple amplifiers, and wide variety of devices connected that becomes more of a challenge. Would be nice to know if it is worth the effort to organize all the cables neatly or does balanced cables eliminates any potential problems.

I use a voltage tester on high sensitivity so it gives me that extra couple inches from where it picks up a current other wise electrical interference on standard is not much then a inch or two. Use it to keep speaker cables apart from each other as they have a current it picks up. And thx to my brother i have some conduits made by icore who produce stuff for the military and airlines to avoid 0% electrical and radio signal coming into your cable. i have put about some on my power cables and on high sensitivity the voltage meter picks up 0% of electrical current. Only have it because when icore would make a mistake producing the conduit it would get scrapped lol lucky for me simple thing like couple mm wide or thin made it defect lol. Even have there conduit that has a metal braid outside then the conduit inside it and that goes for £200 a meter + i have 7 meters of that also thanks to my older brother who worked there.

Thank you! I've been wondering about this for a long time... but was too lazy to do the measurements myself.

[@SwirlingDragonMist]

I once put a pair of bookshelves right next to my amplifier, coiled up the excess wire and stuffed it into the port of the speaker, well the tweeters melted from parasitic oscillation in the feedback of the wire picking up the driver's emited EMi. You may want to add a word of caution on where these coils are placed. A little bundle right next to the speaker is in my experience an absolutely catastrophic mistake. I feel EMi is highly underestimated, especially around single ended RCA interconnects, I'm pursuing braided power cables and toroidal power supplies for that very reason. But just interpreting the "inverse square law" with enough sense to not stuff wires inside your speakers is probably enough to avoid a meltdown ;P

[@bighands69]

My god what sort of a load where you driving. Was it a 100,000 volt system with thousands of amps of fault current?

[@SwirlingDragonMist]

@@bighands69 Naw just some rather forgettable entry level Pioneer receiver from the 70's running Philips bookshelf speakers, the ones with the 2" ribbon tweeters and 5" grey concave woofers. in pretty cherry cabinets. Very nice build quality on those with buttery smooth port flaring. Volume was elevated, but was listenable in loudness. Probably less than 80db. The thing that melted the tweeters was the Parasitic Oscillation, it ramps out of control at high frequencies. Sounded fine.

[@Nelthalin]

Good advice! and great info. It have cut most of my cables to size. But now i was looking into moving the speakers to improve the sound and now i dont have the extra length. To be fair before i cut the cables the speakers where already in that position for months. And now we are 5 years further. But with new insights i wanted to see what i could do to improve. I can move them around a little but not really forward away from the wall. I will just buy some extra cable for the fronts to test if i hear a audible difference when moving them forward. Now they are nicely in line with the center. That center i cannot move forward because of the TV But after seeing your data about coiling up having almost no effect i will keep some extra margin in the future and tuck it away.

[@stevethetoolman2435]

Great video. I’m a avid music listener and your expert advice really helps.

[@CobraChamp]

Thanks for measuring that. I’ve always wondered if it made a difference. Now we know!

[@isettech]

Technically the coil for twisted pair has little effect except the cable is too long with the extra length adding more resistance due to more length, more capacitance due to more length, and more inductance due to more length. Resistance, inductance, and capacitance are all per foot or per unit of length properties of any cable. For test equipment, consider adding a TDR to your tool kit as it can be used to measure the nominal impedance of cable as well as length if the dielectric is known or dielectric constant if the length is known. If your speaker cables were two single conductor wires and you coiled them each by themselves, the yes, you make a solenoid cable. However if you coil a braided, or twisted pair cable, you again have an inductor, but in a configuration known as a Bifilar Coil. The inductance reacts to common mode current on the cable, not the differential mode signal to the speaker. See Bifilar Coil for more information.

Thank you, good to know and thanks for sharing, I have just moved house and need to set up my system again.

Many thanks for your very professional investigation and presentation! As an engineer I totally agree with your findings! It is always important to judge the relevance of values and you really showed the facts with your test and calculations. Impressive!

[@MrBravo143]

I disagree. When coiling a cable, electricity needs run round and round and round.. that makes the electricity tired and confused. So when the electricity reached the speaker it will be so weak and the sound produced from the speaker also tired,weak and confused. This cannot be measured and understandable for normal people. Only can experience audiophiles.

[@Richard-bq3ni]

And the electrons in the outer loop of the wire have a longer path compared to the electrons in the inner loop. So the sound gets smeared. And the electrons get dizzy if course, also very bad for your sound. End that is the end of my very scientific contribution on this topic.

FULLY balanced, of course there is a difference with a two-wire active balanced were cold is out of phase of hot, versus the unbalanced with only the hot connector. Also a fully balanced +4dB output has about 6dB bigger headroom - more dynamic range.

[@blackwaters2400]

Gene, I have to hand it to you, your one honest man that can teach a newer generation not to subscribe to the expensive snake oil around speaker cables interconnects and power cords. I have had systems since the early seventies, and in the later eighties, the industry really went downhill; the small audio store could not stay in business. But a great way for them to make a profit was the high-end speaker cable and power cords (more now than ever). It still did not save them, and they are gone sadly. For many years I got to sit in some small shops and listen and learn and spent some time at Technosonic Studios (now torn down for a shopping mall) in the St. Louis suburbs. Yes, I have spent more than one probably should one high-end equipment, Accuphase, McIntosh, B&W, Sony ES, many Marantz (still have three receivers), double Advents, EPOS, BOSE (1970's), early NHT, Klipsch Corners, LasScala's and Heresey's (my home theatre with Marantz Projector, circa 2007) Except for a few pieces, all were bought used, have had my Accuphase Amps for 41 years. I really get irritated with the false claims and even worse by the adjectives used by so many to describe cables and power cords. But, there was a savior, to saving me probably several thousands of dollars over the last 45 years. Gordon Gow, the CEO of McIntosh, and their lead speaker engineer, Roger Russel, demonstrated to me back in the 1980s that regular old pure copper wire is all you need. Wow, why would they do this? They even put on a roadshow, double-blind, and were proved it over and over. Think about that era; at the time, you would have to say McIntosh was about one of the higher-end products made right here in the United States. There was a manufacturer of audio equipment, and their message was, don't waste your money on all these false claims. They backed it with science and engineering, they were well educated, and they, like you, just HONEST. Gordon Gow is long gone; what an icon and the job he did with that company, but I had also had the pleasure of communicating with Roger Russel (a degreed electronic engineer) and lead speaker designer at McIntosh during those years. Still have the memos. What he and Gordon Gow said 30 years ago, I think, needs to be referenced more today. Most cable manufacturers do not have the education or one-hundredth of the audio industry clout these men had. Yes, it was two-channel audio, but the science is the same. It amazes me how so many people praise McIntosh over that period in time, and how good the equipment was, yet at the same time will disagree with the science of their lead speaker designer (degreed electronical engineer) and the CEO of the company and insist that one must spend hundreds and even thousands on wire. Anyway, wish you would throw those old audio guys some light and try to continue as you do to spread the honesty about what I think is the dark side of the industry. I am sure you don't get many ads from any of the suspects, but that takes an honest man teaching many how to enjoy such a great hobby. These men were well into their careers at even that time. Roger still has his site up; few will ever take the time to read and learn; maybe you can get a phone call, skype or zoom with such an icon? Fellow readers, follow Gene's advice!

Capacitance of long speaker cables is much more of a stability issue in amplifier design. We add a inductor of 0.8 to 1.2 uH internal to the Amp. Extra inductance formed by a small length of speaker cables coiled under your couch might actually not be too bad a thing.

[@guilhermedealmeida2299]

Hi, Gene, Very interesting and well done work. As we can see, the increase in inductance, comparing a cable straight and the same cable coiled is minimal: 2.36uH to 2.56uH. It could be also interesting to compare the cable capacitance in the same both conditions (straight cable and coiled cable). Regards.

Thank you for doing this Gene. I always tell people if you can hear it, you can measure it. Don't relay soley on listening tests, espeically if its someone else listening. And I am not saying different things can't sound different because sometimes they do. Just that if someone is claiming some crazy attribute about something and it can't be measured they are probably BSing you. And just because something measures or sounds different doesn't mean its bad. It all boils down to personal taste. I have some headphones that measure very flat or are on the Harmon target curve. I personally don't care for them. Its just not a sound "I" like. It might have to do with my tastes or my hearing. My old abused ears just don't hear flat anymore lol. I like that you did the test and proved it does actually effect it. Then you did the math to show HOW it effects it and where. You are right, most can't hear can't hear that high (if anyone). Heck I can't hear to 10K if that high. And when I do all I hear is hiss or noise anyway. I am actually more sensitive to bass. I can easily hear or feel down to 10 hertz. I remember years and ago a high shop let me take home and demo some high end cables once. When I brought them back he asked me what I thought. I told him I wasn't sure, maybe they were a bit better but it wasn't night and day. Certianly not enough to warrant the price of the cables. Especially on my relatively cheap audio system. I mean if I could afford and had a 10,000 dollar or up system then sure I guess I would do it. However when your entire system cost like 1500 to 2000 bucks expensive cables didn't make much sense to me. I will give them credit though they looked great and were really well made. And I think they were only like 1 or 2 hundred dollar cables not some of these stupid crazy expensive ones.

[@JonathanDFielding]

Agreed. it has very little affect because the load is so strong, or low impedance 8 or 4 ohm. Do the same measurement on a low line level signal between something with 1v line level RCAs, then coil it and connect it to a high impedance input - something with like 10k ohm input, or even better, into a phone pre-amp.

The energy levels may be small, but add them up like the "Ultraviolet Catastrophy" and the energy across such a broad range of frequencies may be of some subtle significance.

Hey Gene, as an electrician who has done well over 500 RJ45 ends (CAT 5/6/7). I watch videos of people saying we need to maintain the twist as much as possible into the RJ45. I think it’s hog wash because what is 1 to 3 mm going to make in the long run of a cable, that could be as much as 100 meters? Especially inside the devices the cable is plugged into. When the traces on the board travel several inches to the microchip for processing. I know this video dealt with speaker cables. But CAT 5/6/7 are also a big part of the HT industry, as you know. With that said, and with the equipment you have. Can you do a test on a CAT5/6/7? Where one cable has the wires straight inside the RJ45 and an other where they are twisted until the very end? Keeping in mind the frequency the cables are used at as well.

[@bighands69]

Most of the audio bro science is nonsense. The figures involved in such systems simply would have no effect on the current being carried by the cables or the voltage. As an electrician you probably already know the sorts of figures that are required for voltage drop to become a problem and speakers systems in the home are nowhere near that level.

[@kristiankeller4335]

I think the twisting in RJ45 has more to do with common-mode rejection than electrical characteristics. Any straight part has the potential to become an antenna for EMI. It's probably just good practice more than anything else. A few cm of straight wire won't do a world of difference in the error statistics, but it's nice to be safe.

[@user-ex9zm7bg3x]

I cryogenically treated mine for freshness but now they won't stop shivering.

[@bighands69]

It is probably oxidation that is causing a lowering of the potential electron affinity. Or I could just say it is horse crap.

[@SunsetWingman]

I don't coil my cables, I do a zig zag wave thing. That way when people ask me why I do it I can spout off some crap they have never heard of and look smart... True audiophile lol

[@danielsh1015]

It sounds counterintuitive just to think there’s a difference in sound between a coiled cable vs a straight one. Who comes up with this, Fremer?

[@ASSOpid]

I guess you've never heard of cable elevators or lifters. Yes they are real and yes people really do believe they can hear a difference.

[@jondon9963]

Just saw an add for a cable lifter in latest issue of stereophile, “fog lifter as per audioquest” and could not believe that there is a company peddling this nonsense.

[@danielsh1015]

@@jondon9963 Unbelievable. I just saw the ad myself. Yea, really, do we need to run multiple tests with highly technically sophisticated instruments to find out if the fog lifter really work?

I checked out Audioholics take on the other current topic of interest. Power cables. "Do audiophile power cables make a difference?" Uploaded June 2020.

[@harpalchauhan428]

Would there be any chance of a video ,about what are the effects of having power cable in coil, compared to figure 8.

[@mechtheist]

Did you go with a right-hand coil or a left-hand coil?

[@kilgoretrout5456]

You can buy a perfectly functional and accurate LCR meter for like $100. The DER EE LCR METER DE-5000 is an excellent choice for a very cost effective, but accurate meter. Just remember to calibrate it relatively frequently, and you’re gtg. It only take me 60 seconds.

Gene my friend! You're the new "Cable Guy" but obviously not, Jim Carrey. Lol 😆. Anyways cool video. Knock! Knock! Knock! Its the Cable Guy! 😂 Crazy film that Gene. If you haven't seen it, watch it. Its funny!

[@Quietprofessional1]

That's good news I would presume that the amount of shielding you have matters too.

[@fubartotale3389]

I am literally doing this now on cables in my secondary system, I haven't had the time (too lazy) to shorten them. But I have literally never given this a thought till right now. .

[@stefanfrankel8157]

Shortening changes the resistance as opposed to the inductance. Might I suggest folding the cables back and forth like a ribbon rather that coiling them?

[@bighands69]

Making cables shorter is going to have effect on the signal voltage or current.

[@jasons7070]

Look...I read the description of the video and listened for the first 30 seconds or so. As a former certified professional in the audio visual industry. I'll leave it at this...if your so concerned about the coiled cable becoming an inductor don't coil it (over under if you do ;-) make it into a figure 8 pattern. Done. still won't make any difference in low current applications

Would be good to see the inductance looking into the speaker *(rather than the presumed 8 ohm resistance). I bet the cable inductance would be rendered insignificant (less than one tenth) in comparison.

[@kelvinlee7423]

Can try to measure CAT7 LAN cable compared with normal speaker whether any significant difference

Hey Gene would it be possible to make a video about good quality affordable component racks?

[@josephreynolds6844]

I’m constantly getting into heated debates concerning speaker wires and the differences they make. Comments like “I heard a huge difference after I purchased brand XYZ speaker cables for $80/ft.” I’ve measured lots of cables at high frequencies, (>1MHz) they make a difference. Audio frequencies are not high frequencies.

[@stefanfrankel8157]

The only reason I coil speaker cable is when my speakers are at different distances from my amp. I like to keep the lengths of the cables the same, so I end up with one cable stretched out and the other one either wound up or folded back and forth. I would love to see what happens to the measurements when you have different length cables going to the speakers.

[@rabarebra]

You'd see nothing.

[@joeythedime1838]

What would this mean if you need to coil a few loops with interconnects? I have ~3 loops in my balanced XLR interconnects.
