I discovered decades ago that high quality speaker cables dramatically improved the KEF speakers I had at that time: more spacious etc. As an engineer, this seemed likely because of the relatively high current involved after the power amplifier but I remained a sceptic about interconnects at signal level, ie from CD player or network player to the amp. No longer! I became convinced to lash out £50 on an RCA interconnect by PS Audio and boy, did it make a difference. I was completely gobsmacked that changing the cable carrying such a tiny current could make a difference but it did! Now you’ve convinced me to at least try bi-wiring which I’ve also been sceptical of. I love experimenting.

[@markcarrington8565]

Hi Kelvin, nice video and I've just subscribed to your channel too, so thanks. I agree, I bi-wire my main system using Mogami W3104 quad cable, which is fantastic stuff. It doesn't take any components out of the circuit, but it does separate the signals in the wires, reducing crosstalk between high and low frequencies. This is the part that some people don't actually believe, of course, because they think that it's all the same at the amp end. I agree with you on interconnects too. I thought I'd have a go at making my own and I love them so much I sold all my Chord Company cables, even though I'd been using them for years.

[@Anybloke]

I've tried biwiring my Mission 760iSE and I honestly can't tell any difference. It only really works in systems which use active crossovers and bi-amping; one amp each for HF and LF. I'm not convinced by cables either. They are basically just copper conductors carrying a small voltage. The only things that really matter are; 1. Never use that thin crappy "bell wire" stuff, 2. Keep your cable runs as short as possible without over tensioning them. 3. Make sure your banana plugs (or whatever) are properly connected to the cable ends; preferably soldered.

[@grantwilson4696]

Hello Kelvin. We've all heard a lot of the arguments around the effectiveness of cables. Like you, I enjoy swapping gear out to listen to the same track of music to see what the differences may be. I hadn't put a lot of belief in cables making a noticeable difference... after this episode I'll be checking it out. Also.... thanks for explaining about bi-wiring... I'll be giving that a go as well. Cheers from Canada!

[@ar_xiv]

if you really want to hear a difference with cables, use some thin crappy wire on one speaker and some nicer 12 gauge on the other. you'll notice right away the issue. whether this is just a loss in "a few db" as a recording engineer might say, or something deeper in the sound, I haven't investigated enough to know, but you know what people who care will say.

[@finscreenname]

If you bi-wire to separate channels on your amp and if your amp has gain controls you can tweak your high and low outputs and change the sound. Throw that in with an EQ and you can use lamp cord (which back in the day was 12ga solid copper) and it won't matter.

[@kevinlawton9661]

Once again, I have to agree with you. Sensible choice of cables when bi-wiring is usually a worthwhile improvement. The next step, bi-amping, I have found makes an even better improvement. The ulimate, going 'active' using active crossovers instead of the passive ones inside the speaker cabinet, can make a massive difference.

[@raymcnamara7843]

Head to the shed and nick the cables from your old Arc Welder, and hook them up to your system. It worked very well for me for 25 years, until I invested in some quality Japaneses Speaker Cables of a similar gauge (thickness), 15 years ago. Thicker Cables do take wrestling to get them were you want. Also depending on the Banana Sockets Mounts, you may need to suspend very heavy Cables to remove pressure of the Banana Sockets. SCIENCE: Signals move along the skin of a wire, so the more wires, the greater the surface area the signal can use. Also the lower the Resistance, less energy is lost (heat). The more pure the copper used the easier for the electrons to travel, the more efficient the cable, and lower resistance.

[@bartvanransbeeck1341]

Bi-Wiring is just OK, you should consider Bi-Amping, a whole different level in sound! Just make sure you remove the metal bridges(Jumpers) between the 2 speaker terminals or you will fry your amps!

bi amping can actually sound worse due to phasing issues, im a musician and can vouch for this. there is always a delay of sound between amps unless they are identical and serviced.

[@manzanaresantonio]

@@Synthematix I use an active crossover, it eliminates that issue and I can equalize my speakers to my liking. I use a tube power amp for the midrange and high frequencies and a solid state power amp for my low frequencies with great results!

[@zedcarr6128]

As an electronics engineer by trade and as a guitarist by hobby I will say this. A speaker / audio transducer is an electric motor. It converts electrical energy into mechanical energy. As long as the cables can carry the voltage and current then it doesn't matter if there is one or two cables.

[@ankithmistry]

[@johnsweda2999]

depends on the interconnect resistance you need to go for coaxial cable 75 ohms for interconnect if it's digital source, analogue source go for 50 Ohm's into a preamp or Poweramp 50 ohms give you about 2 of 3 DB drop in output what is preferred for solid-state don't do this from valve stick with 75 ohms. Belden cable is probably the best cheapest. Always use 60 50 or 30 ohms possibly from turntable to preamp don't go with 75 ohms this will give you less output as I said but makes a cartridge more sensitive

[@ajv802]

In my experience it does improve sound quality and the noise floor lowers but ONLY when bi wiring is done and healing crystals are placed in a deltoid pattern at the base of the speakers and amplifiers. Works even better with crystals placed around the source aswell as on the listeners pants pockets.

Aaahhh No!! Biwiring does not REMOVE circuitry! How could it? What have you removed? You have ADDED twice the cable... You've quite literally INcreased circuitry. Think of cables as resistors (and they are). What you are doing is changing WHERE the cable resistance is placed in the crossover schematic. Yes..... Biwiring can change the sound. But not for the better, in my experiences. It's just different, and it's probably not how the crossover was voiced by the designer. Adding resistance between the High and Low halves of the crossover will change the sound, and it's likely that the crossover was designed with the 2 halves connected together (ie... both halves being driven by the same EXACT signal). If you separate that connection at the crossover input, suddenly both halves are not seeing the same exact voltage signal. I've found that driver integration suffers with biwiring. Your mileage may vary.

[@whitecrowuk575]

If you like the tweaking you can do with cables, you can use for example Belden cable. High capacitance leads to the suppression of the higher frequencies somewhat.

[@Detailverliebt]

Hey Mate, sorry to say that but you are talking a little rubbish here. Your description about the sound difference is almost right and what you said about mixing different cables is correct too, but your technical explanation sucks ;-) 1st - Your tweeter cable does NOT connect to the tweeter directly, not even with a x-over of the 1st order (just a capacitor in line). And not one cable (pole) either. Yes physically you are connecting it directly to one side of the coil of the chassis but this is not how an electric circuit works. Remove one pole and there is no circuit anymore. 2nd - It does not sound better because you have double the cable. Different frequencies travel differently over the cable. Lower frequencies need more power so they benefit from cables with larger cross-sections When you do bi-wiring you have effectively doubled the cross-section, but only one pair is connected to the woofer, so the effective cross-section stays the same. Higher frequencies benefit from larger surfaces or surfaces with a lower impedance, that's why silver-coated cables are more brilliant on the high frequencies. But the same that goes for the woofer is true for the tweeter, yes you doubled the surface but you are only connecting one pair of cables, so the surface area that connects to the tweeter stays the same. So the question is why can you still hear a difference? Is it psycho-acoustics? No it is not. The difference is that you extended the length of the connection between your woofer and your tweeter and therefore you obviously increased the resistance. You had like 2cm before bi-wiring, now you have 6m cable between them. When the woofer starts to resonate it creates a higher frequency signal by itself, and this signal feeds right into the tweeter. With bi-wiring you are suppressing this feedback by the resistance of the cable, that's it. So what you hear is a more precise soundstage and details. Your impression that maybe even your midrange sounds better in kind of true and false, yes it sounds better because the harmonics are better recreated by the tweeter. Now be brave and do one about bi-amping so that I can really start laughing ;-) I am just making fun of you, good channel anyway coz at the end all that matters is how it sounds like, trust your ears, they work well!

[@stereoreviewx]

When I looked inside one of the Twitter terminal just go straight to the tweeter

[@LeeTanczos]

Omg I thought you were going to debunk right here but I’m not sure if you did. The biwiring makes the low and high frequencies travel in separate cables. This is like man and wife travelling in same car trying to achieve favourite shopping destinations. Neither is 100% happy with their shopping productivity. With biwiring, it’s like the two shoppers can go in their own separate cars. They are no longer affected by each other’s journey at all. So for each one, the trip is more efficient. Heavy currents of bass notes can affect the phasing / timing of higher frequencies travelling in the same cable - THIS IS THE REASON biwiring works. If you ever find your system sounds better when you make sure no mains wires pass near any interconnects... same thing.

[@Detailverliebt]

@@LeeTanczos Sorry but this is not true since you are still splitting the signal in low/high frequencies in the x-over located in the speaker, not at the amp. Both cables carry the same signal to the speaker.

2:15 The second benefit is "This wiring will go direct to the tweeter without going through the crossover". I am surprised by such a lack of understanding. I've been designing high performance speakers for over 30 years and have never provided a bi-wire option. If anything, having the option to bi-wire on a loudspeaker can often mean the crossover is less optimally designed than it could be. Manufacturers don't believe it makes a difference, but are compelled to include them for fear of losing a sale to a competitor. I guess one cannot argue with the claim, "but I can hear a difference" because those making the claim refuse to be subject to any form of controlled test, but at least it allows the rest of us to judge the credibility of their opinions about other aspects of audio. Sorry Kelvin, I have the greatest respect for you and I always enjoy your videos, but was disappointed by this one. I would have thought someone like you would be dispelling these myths not reinforcing them.

[@spudpud-T67]

Some people seem to think the lows keep obediently to one cable and the highs to another. It's the same signal in both wires arriving at the speaker terminals. Bi wiring is an example of the placebo effect.

[@rogerwebb7501]

​@@spudpud-T67Wrong! Why cannot people look into this from an electronics point of view? Because of the load provided by the tweeter and high pass network, and the woofer and low pass network, which are completely separate in the biwire configuration (the jumper links removed) the demand of the load in both cases is different, ensuring that the high frequency current travels down the tweeter wire and the low frequency current down the woofer wire.

Cables, they certainly contribute to the sound but it is nothing significant. But Bi-Wiring certainly do contribute quite significantly to the overall sound quality. I would say even more than 4%. In my case I would say that the sound betterred by even 10%. It was audible at first listen immediately.

[@spudpud-T67]

Do you have a cross over in your amp before the output terminals? Otherwise the signal is the same in the two wires to the speaker but then filtered after the speaker crossover. Hearing bi wiring differences is the perfect example of placebo effect.

[@rogerwebb7501]

​@@spudpud-T67As I've pointed out before, the two elements of the crossover are separated by taking out jumpers between the upper and lower terminals. You now have two completely different 'branches', the point at which the highs and lows branch being now at the amplifier end rather than the speaker end. The high pass filter will 'demand' that the high frequency current flows along the tweeter wire, and the low pass filter will 'demand' that the low frequency current flows along the woofer wire. That split point at the amplifier end is, in a single wire (normal) configuration, inside the speaker cabinet - usually part of the printed circuit board for speakers with one pair of terminals.

@@spudpud-T67 It's not a theory, it's a scientific fact! It IS how a crossover and its associated wiring works!

I think the trouble is you don't understand WHERE that split occurs. Ina biwire setup the split is dragged back to the amplifier end....rather than being inside the speaker cabinet.

Coupla things. BW is all about commning the input to the speakers back at the amp terminals, not so much that one of the input wires runs direct to the terminal of the tweeter.

[@djwindhoek]

As I understand it, bi-wiring is simply a case of supplying power to a speaker via 2 positive and 2 negative connections, with the bridging plate removed, of course, but from one amp output only whereby the 2 positive connections are joined together to make 1 connection, and the same goes for the 2 negative connections; you actually described this process at one point during the video. What you're doing is bi-amping: you're effectively supplying power to the speaker from 2 amps, using 2 positive connections and 2 negative connections at both ends, again, with the bridging plate removed. In a way, bi-wiring simply moves the bridging connection from the back of the speaker to the terminals on the back of the amp. The main change is due to the extra 'cable thickness' by using two runs of cable.

His speaker was ‘bi-amp’ at the start of this clip. Using speaker A and speaker B for tweeter and woofer separately is bi-amp, using only speaker A and connecting 2 wires to tweeter and woofer without the bridge is bi-wiring, otherwise known as ‘I don’t have 1 thick cable so I will use 2 lengths of thin cable’.

[@stereoreviewx]

Well it’s an interesting picture you paint if I can’t hear well but I think I can hear differences in cables which I certainly do. I mean my whole channel is full of me talking about small differences. So I must be either deluded on a monster scale or I know what I’m talking about. You can decide. I certainly want to do some blind tests by the way they’re just a bit more tricky to film. K

@@stereoreviewx Placebo is much more likely why you think you hear a difference.

[@zedcarr6128]

If your tweeter is a piezo transducer then virtually NO current will be flowing through the cable feeding it because they are voltage controlled devices NOT current controlled devices like a moving coil speaker. I suggest that people who are into HiFi, educate themselves in electronics. It will save you a lot of money. Or just ask a qualified electronics engineer on the Interwebs.

[@colincts]

Great watch again ... Quick Q are your BC1's modified for biwiring ?

[@stephen579]

Bi-wiring is only possible if you have A+B outputs on your amp, otherwise, you are just connecting both wires to the same output.

[@MrRawMonkey]

“You know”

[@MC-bu6ez]

So forgive me for saying so, but your explanation of HOW to bi-wire is poor and uninformative. Why do people make informative videos, which don't inform? Pointless. I want to know how to actually do it step by step, not if it sounds better, I wouldn't be doing it if it didn't!!.

[@artsmodelstation9396]

Tried it with my Cambridge axr100 and Klipsch rp5000f speakers. I did notice sound improvement and seems now have to apply less powers to speakers.

[@snuffpappy]

Could you sometime show the inside of a speaker that has two sets of speaker connections. Im still not clear on why biwiring helps. Id be curious to see the signal path. Thanks!

[@nickwilliams1065]

Long winded and miss leading, Bi wire = both red cables at the amp end into red socket and at the speaker end the 2 red wires connect to the red sockets, same idea with the black cables. Bi amp which is what your showing, requires 2 red and 2 black at both ends connect as you would for left channel and then connect the other speaker the same using the right channel outputs.

[@germusic2022]

Thanks mate ,good info,can you tell me what you think of subwoofers connected to Hi-Fi systems for bass,...any more songs reviews for Hi-Fi,cheers

[@stereoreviewx]

Well I can’t say I’m a big fan of subwoofers some of them the base is very soft Also I know bass is not very directional but it is a little bit I prefer it coming out of my two speakers . If possible. Truly it’s not something I’ve messed around with much mostly heard in other peoples places was never that impressed doesn’t mean it can’t be good Cheers K

Speaker cables haha, good old twin multicore copper is all you need with a marker stripe

Twisted pure silver or silver plated in cotton or PTFE insulation sounds a liitle better, but I agree, the expense is injustified, if the system is not up to scratch.

[@MrRichymil]

@@paulb4661 hi I had a friend with thousands and thousands of pounds worth of Linn equipment, he swore by using solid core copper wiring the sort that electrician's use for your plug sockets.

Hi! Do you have any schedule on when you'll hold live chats?

[@drs-Rigo-Reus]

direct to the tweeter? hope not, there will be a resistor and/or condensator. A cable lights or lower energy slightly, enhancing or lowering the frequency range. Tweaking money should go to a better source.

[@Noah-gq7pq]

what your talking about is crossover ,,no how many wires you use you need a cross over ,,this is new to me ,,,,

Bi-wiring only makes sense if using different type cables

[@bartvanransbeeck1341]

I notice with respect your honoust observations....but i was also impressed by a blind listening test one can see on utube between a highend expensif sysyem and wires and a very cheap , with cheap wires ,both with the same small ATC 2way speakers....the cheap used behringer poweramp with sony cheap player...the other used YBA pre and poweramp ,top expensif cables , yop teac vrds cd etc....most coulnd't tell difference and about the same amount of listeners prefered the cheap or the expensif system...all trained hifi enthusiasts and equipment hidden , only speakers apparent....notice the amps are both 2x100 watts with generous trafo....because clipping from underpowering is easily exposed

[@stereoreviewx]

That sounds interesting I was going to try something like that but to be honest it seem too complicated but it’s a good idea

[@Ribanski]

Totally BS. Open up your amp and you would see that your connectors are interconnected to each other. So it doesn’t really matter if you leave your Amp with one cable and then connect to the four speaker connectors or run two sepperate cables from your amp to your speakers. Also your High. Mid and lows are separated on the Crossover. So there is absolutely no need for Bi-wire ring.

[@26Jorgeb]

Hi Kelvin, I want to try this but my speakers, Dahlquist M905's only have 2 terminals.What should I do?Thanks.

Nothing you can’t do it K

[@26Jorgeb]

Thanks a lot

[@andrevanstiphout]

Do what the speaker manufacturer wanted you to do!

[@lexluger3490]

It makes absolutely no difference. Logically and electronically to think otherwise is insane. Using modern speaker cable you will get no difference. The A and B terminals on the amp receive the same power, when using both they are bridged, just like the bridge plates on the speaker's terminals. So you've effectively removed the bridge plates from the speaker end and attached them on the amp end... how is that making any difference?

[@spudpud-T67]

No difference to reality but big difference to the placebo effect.

[@zindahoon]

Hi Kelvin , can you please show us your Arcam CD player and also tell us how it is different to modern Arcam or other CD players ..

[@ronniechowdhury3082]

Why is it getting better? If you do a REW sweep with single wiring and biwiring/biamping what you'll see is that the signal arrives at the tweeter and woofer arrives faster because it bypass some of the circuitry. The best sound is when both tweeter and woofer are flat SPL across frequencies and most importantly phase aligned too. The first is handled by having 2 amps distribute power (2x more power needed for each octave lower). The second is what smears the sound. Both can be corrected by a DSP scientifically. This is what you are hearing perceptually. Of course better components, better build quality helps these metrics but they are all quantifiable measurable metrics

[@J0hnny8ravo]

I don’t really believe in bi-wiring. The crossover in the loudspeaker separates the frequencies sending the highs to the tweeter and the lows to the woofer if you single wire. Now, in bi-wiring, we bypass the crossover and by doing this we feed both the tweeter and the woofer with the full range of frequencies. It’s not a secret that tweeters in general don’t cope well with low frequency and some woofer get “distracted” by high frequencies.

[@ProffAndy]

Bi-wiring does not bypass the crossover. Bi-wiring results in low range frequency current being carried to the bass driver with one cable. A separate cable carries high range frequency current to the tweeter. Despite being connected together at the amplifier, the two cables are carrying differing currents to the speaker drivers. The crossover in the speaker is still in place and doing it's job.

[@spudpud-T67]

@@ProffAndy How do the cables carry highs in one and lows in the other? Magic? Unless you have a crossover in your amp the wires are all carrying the same signal. It's measurable using a spectro. The speaker crossover does all the filtering. Bi wiring is the perfect example of enjoying a placebo effect.

[@ProffAndy]

@@spudpud-T67 No magic required, just fairly simply physics. I get that the concept of bi-wring can be confusing, and it can seem that there's no way that high and low audio frequency currents can be carried separately by two cables connected together at the amplifier, but that is exactly what is happening in a bi-wire configuration. I`ve tried to explain this a fair few times, and usually my explanation gets ignored, or simply dismissed as nonsense. I have never claimed that bi-wiring produces any audible improvement (or even change), just like I'm sceptical about claims that different types of speaker cable can make very noticeable changes in audio. However, there is no doubt that different speaker cables will have slightly different electrical characteristics, which in theory will alter the current flow through the speaker (usually by a miniscule amount ). Switching from single wiring to bi-wiring will in most cases alter the current flow through the speaker drivers to a slightly larger degree than simply switching to "better" cables. Is that change in current flow enough to be detected by human ears ? I'm not sure, but bi-wring does "split" high and low frequency currents which are carried to the speaker in separate cables.

[@spudpud-T67]

@@ProffAndy Unless you have a crossover in your amp you get the same signal passing along both wires. Only in the speaker crossover does the signal get filtered. What I'm poking fun at is people thinking the treble and bass signals obediently take different cables. Check the cables with a spectro to show same signal at the end of all cables coming from single amp. However contrary to you statement above "bi wiring doesn't make improvements" it does improve sound but only as a placebo effect.

[@ProffAndy]

@@spudpud-T67 Ask yourself "what causes a speaker driver to move, and how does it reach each driver".

[@sergiolams]

I only believe in Bi Wiring if you plug tweeters on A and Bass on B that is using A+B together.that is two channels on your amplifier.4 outs on the amp.if not is all shite.

[@bowiekent492]

Hi there I liked your video. I'm I the process of making a little stupid for my garage. I have an arcam xeta one a/v amplifier. Is it possible to get some sound from it? With two celestial k12t-100 with tweeters all running off of one cable it seams. I can't see in the housing to see what the tweeters are. And input is large jack. Any help would be appreciated. Also there are many ports on the back of the amp do I just head for the loudspeaker outputs. Although there is front, surround and centre.

[@THEHULK209]

Forgive my ignorance but wouldn’t it be the same exact thing if I just got a thicker cable??? I don’t the bi-wire.

[@user-el2zj3pw5r]

Whit bi wire connections we need to remove shorting bridges yes, but why?

[@paulb4661]

Because if you don't, current corresponding to the frequency dependent load presented by the tweeter for the HF branch and Low midrange driver for the LMF branch will flow in both conductors defeating the whole objective of separating them.

[@brucebruce3841]

You only need to remove the bridge when you bi-amp, as you are using 2 seperate amplifiers (speaker A and speaker B). Just like at the start of this clip. If you are only using speaker A, you can use as many pairs of cable that you can physically fit, or just use 1 thick cable and leave bridge plate in. there is only one source from the amp, so all frequencies go to both tweeter and woofer.

[@Synthematix]

Remove those bridges and throw them away, they can completely ruin the sound quality because theyre directly causing mixing the tweet and mid signals.

[@Synthematix]

@@brucebruce3841 Nothing to do with having one source, AC current can flow in many different ways at the same time, only DC wouldnt see any benefit from biwiring, but as audio is AC you are wrong. twin wiring 1. allows twice the current equalling in less stress and resistance is halved, 2, allows your tweets to be fed with proper silver cable not copper, 3, the bridge plate does more harm than good.

[@brucebruce3841]

@@Synthematix ok, I’m not an electrical engineer, just someone who thought they knew a little bit about home audio. so I quickly looked up how electricity flows through copper in AC. It talked about skin effect and higher frequencies travelling on the outside of the copper. Does that also mean for bi-wiring to have better benefits, the second wire should have thicker strands of copper? and would more seperate strands - say using 10 cables not 2 give different results as well?

[@speedy1979]

Thanks a lot for the video. Question: If I did example b (bi wiring out of one set of terminals in the amp), and wanted to hear my tweeters alone -by some strange reason- by unplugging the woofer...would that fry my tweeters?

No that should be alright I did that just listen to the tweeter and then the woofer
