Now; 200W is ridiculously loud

Continuous yes, for transients, no.

Re. that REL subwoofer, he's playing at it. I remember many years ago a for sale advert in Gramophone magazine (yes Grandad) for a house!! It had concrete folded horn bass bins built into the basement.

@somafunk

How did you find the sweet spot for the sub? I've got a similar setup, albeit with much older gear 🙂 I know sub bass is unidirectional (if that's a real word) so it doesn't have to be right in the middle. But mine is at the moment just cos it looks good and sounds ok. Just wondering how to double-check it's actually in the best position. Also do you know anything about phase when it comes to a sub. Mine has a 'phase' button on it which I've just let my ears decide what setting it should be. I suppose if it sounds right it is right.

I used to be obsessed with this stuff. I even tried to turn my hobby into a job by working in a Hi-Fi shop for a while.

I learned 2 things: A significant portion of people visiting hi-fi shops are weirdos AND there is a lot of utter bollocks spouted when your get to the "high end".

Cheap things that definitely worked for me back in the day:

Proper speaker placement: Its amazing how many people don't really bother and just whack their speakers in the corner of the room, where invariably they sound terrible.
Speaker stands: "Bookshelf" speakers always sound better on stands but you don't need to spend money on really expensive ones.
Mass loading: I had Mission 733 floorstanders with a cavity for mass-loading at the bottom, you poured in a bucket of special acoustic metal (swarf) and the increased weight made the speakers sound a bit tighter - it definitely worked but only a few speakers were designed this way. There was also a non-trivial chance you might have to explain to a Policeman why you left a bucket of shrapnel in the middle of the concourse of Glasgow Central Station.
Modest room treatment: If you have wooden floors consider a rug.

Speaker cable? I'd say that half decent cables with good quality terminations make you life a lot easier when installing hi-fi gear. By half decent I mean ~£5 a metre. As I said above a lot of places will do end of a reel off cuts really cheap.

I’ve got a similar setup, albeit with much older gear 🙂 I know sub bass is unidirectional (if that’s a real word) so it doesn’t have to be right in the middle. But mine is at the moment just cos it looks good and sounds ok. Just wondering how to double-check it’s actually in the best position. Also do you know anything about phase when it comes to a sub.

If the sub was out of phase it would sound really wooly and loose. Unless the setup is really weird or the sub is really far away from the main speakers, it should be left in the default position, i.e. in phase with the + and - of the main speakers.

Setting up subs with stereo speakers is a balancing act, you obvioulsy want it to add to the punch and depth, but it's very easy to overcook it and have a very boomy/bass heavy overall sound.

Rule of thumb I use it that you shouldn't be able to tell there's a sub plugged in, it should just provide enough low end oomph to compliment the main speakers and enhance the overall sound.

jambourgie :How did you find the sweet spot for the sub?

matteyfez has phase covered - its either right, or its wrong - quite a noticeable difference, as for the sub placement its a matter of moving the sub around the room till you are happy, for example corner placement can increase the bass response - not always favourable as it can bloat/muddy the definition, and different materials in back/front/side walls can affect the sound - I have two plasterboard stud walls (front and right with a door opening) and two dot & dab plasterboard over block walls with a ruddy big window (left & back), Ideally/aesthetically id have liked to move my sub to the back left wall firing across the room to the plasterboard wall to free up space under my desk but it sounded loose and bloated in that position due to reflections and a problematic room mode. In your situation id leave the sub where it is and play a bass heavy track, move around the room and in certain places which are more likely to be corners of the room where there is freq build up you will hear a noticeable difference in bass response (or "whomp"-technical term), try moving the sub close to/but not in the corner where you feel the deepest bass and then sit back in listening position. Placement away from a wall (my sub is 45cm from front wall but even 10cm can make a difference) can help with a balanced sound and adjusting the crossover (start with it set at 80hz) is essential as is the volume you have it set at. Once you have a suitable position then ensure the sub is decoupled from the floor. What you want is to hear and feel the bass response but not to be aware its coming from the sub itself.

What speakers are you using?, what is their freq response as this will determine the sub crossover?

Theres loads of info on YouTube regarding sub placement that will explain it far better than I can.

I’d be surprised if anyone on this thread hears much above 15/16khz tbh.

i can *just* hear 17..

Think it might be, I heard some weirdness on the 20khz one.

Try this, just youtube, but the sweep is good for identifying where dips are etc. I can't hear above 13, but interestingly there's weirdness that happens from 2-8khz for me, not deafness, but noticeable dips and crests around there Showing that I've not got accurate hearing there anyhow.

Volume makes a difference too. be careful with that, cause it can go right through you, start low! 😆

obviously, speaker/headphones, will affect this, but it'll give ye a fair indication and starting point if you want to investigate further.

age is a massive actor, if you are hearing high, I'm gonny say you're on the yonnger side of life! 😆

ps I'm fine with my 13k limit. there ain't much music happen above that anyhow! 😆

pps, should I will be able to hear above that, as music isn't pure sine waves

While being sat comfortably is crucially important, monitoring using a chair with a big headrest type design is going to really affect what you are hearing.

nice tidy setup BTW 🙂

and there is plenty happening in music above 13khz

Some, but the vast majority of it is below that. 😆

pick a song, any song, and I'll stick a 10k filter on it, and we'll see how much music there is happening above there. 😆

@mattyfez

Thanks for the phase explanation. I think I've overthought this and didn't realise it was as simple as that.

@somafunk

Cheers for the tips. I might've got lucky and it's already in a decent position. Certainly not experiencing any specific issues. But always eager to improve things if possible which I'm sure you understand. Yes, there is a really heavy bass area, on the other side of the room near an open door. Never thought to move the sub over there... As it is, it is decoupled from the floor, placed on a paving slab which in turn is placed on four halves of tennis balls. But it is pushed back against the wall, well, a radiator, prob ten mm gap so I can reach the cutoff/volume controls on the back. Think I've got it set somewhere in the region of 70-90hz. Hard to tell from the front, just adjusting by ear. The room doesn't seem too bad as it's carpeted with a big old sofa etc. Monitors are Yamaha NS10M Studio. Proper ramshackle old setup.

Will watch that sub setup video now, cheers!

The youtube sweep thing is amazing. I start hearing super high tinnitis whistle as soon as it gets to about 200Hz (that doesn't go away when I pause the vid!), then about 600Hz I start hearing another higher but constant 1200Hz ish tone as the main tone catches up to it. Then all sorts of strange high pitched noises up to about 11kHz where it goes quiet. With noise cancelling off, a different set of effects.

You won't hear much with the low pass filter, but it would be interesting to see what happens to the music if you set a high pass filter and switch it on and off, if you can tell.

Yeah that would be a fairer way to do it., I know for me it doesn't make a great deal of difference, but peoples mileage will vary, we've all got differnence hearing. The good tones are all in the 20-10khz range for me!

Well, I just downloaded a frequency generator app, that lets you play up to three frequencies. My top end is about 12kHz on this. I tested it on my nine year old daughter, she can hear up to about 16.5kHz so the equipment (the Mac, the bluetooth connection and the headphones) are capable of delivering sounds I can't hear.

Then I put one of the knobs on a lower frequency and I turned the second one on. I could hear both, until the second tone went up to 11kHz, but then after that I started to hear all sorts of other effects on the main tone caused by adjusting the high pitched one, all the way up to 15.5kHz.

Now this is highly likely to be related to beats and interference, possibly artefacts of the way the sounds are generated and the fact it's digital, but beats would still be an issue in a fully analogue setup. So this quick experiment suggests that it may be possible for inaudible frequencies to affect the audible ones. And even if it's a digital artefact, most music is mastered digitally now isn't it?

I got the 3.5mm cable out though and the effect disappears with sine waves, but with square waves all SORTS of weird noises are happening. Even with one tone.

Also - the sine waves seemed the same between 3.5mm and bluetooth, but when I play actual music, there is masses more bass with 3.5mm. The song doesn't have any deeper tones in it - when the bassist plays a note the root note, the mode of oscillation is the same frequency and definitely within the audio range - but there's unquestionably far 'more' bass.

Sounds about right, the NS10M does not have much of a response below 100hz so you are probably in the right ballpark for crossover frequency. If you can be arsed then have a play with sub placement in your room - may offer a benefit or may not - let your ears decide rather than advice from a gob on a forum😉

molgrips,

what's the app you are using? to I have a gander, not really sure with out looking.

as for headphones, I use sony xm4s and I notice no difference with them wired or bluetooth. There's a difference between noise cancelling, off/on and ambient sound, but that's to be expected. But no difference wired or not, could just be quirk of your earphones.

If you are trying to get an accurate monitoring system using NS10's you are going to have a bad time.

They are common in studios because everybody knows what to expect from them and its not because they are accurate, quite the opposite.

Most audio apps will have a tone generator plugin, a 20-20khz sweep will probably surprise you in how certain frequencises will seem to vanish and others boom out when in your sweet spot.

Also interesting to set a few spot frequencies and rotate your head around or lean forwards/back. Then take a walk around the room as well.

Not shure of what kind of compression will be on the audio over web type tools, but using a test tone that has been through any type of data compression is probably worse than useless.

Don't assume it's accurate or the device your using it on is physically capable of generating very high or very low frequencies.

Or if you can actually hear them, anything below 20hz or over 25000hz requires a good sound system and good ears. I.e not an app on an iphone.

Yeah, weird.

I can hear: 8; 10; 12 (with the volume wellied right up);

I cannot hear: 14; 15;

I can hear: 16; 17 (just); 18 (again, just)

I cannot hear anything higher.

Presumably then it's more complex than "above X..."?

Volume makes a difference too. be careful with that, cause it can go right through you, start low! 😆

There's a thought. Can too-loud a noise do damage to your ears if it's at a frequency you can't hear?

pick a song, any song, and I’ll stick a 10k filter on it

Having just gone through those tests, I think I'd want it filtering out.

@cougar

You have a two-lane motorway. It’s congested, so you expand it to a three-lane motorway and then you see traffic is flowing freely.

Where’s the discrete point here then? Shall we build a four-lane motorway? Why? A 9-lane? A 47-lane? A thousand?

There is no “discrete point” because that’s not how analogue works. But you don’t need a pipe seven inches wide to supply a bath tap, the water ain’t gonna come out any faster.

You're using 2 different analogies there and not saying how they relate to the situation. Water and traffic are different you say hit it seems to me the 3 lane motorway will let 50% more traffic flow (speed and distance between cars remaining the same). It's not like one is gridlock and the other is free flowing, that's not credible.

So it's about resistance? The mains cable is sufficiently conductive but the bell wires isn't?

You concede there's no discrete point but your previous claim is that the mains cable is past the point at which there is no improvement. Doesn't make sense to me.

Frequency Sound Generator on Mac App store - it was 99p though!

Or if you can actually hear them, anything below 20hz or over 25000hz requires a good sound system and good ears. I.e not an app on an iphone.

I verified the setup could produce sounds higher than I could hear by testing it on my daughter. She could easily go up to 15kHz, and vaguely up a bit higher.

Just realised that I didn't turn the volume up at higher frequencies so we could maybe both have eked a bit more out. 15kHz is low for a 9 year old kid.

Presumably then it’s more complex than “above X…”?

My guess is that it's artefacts of the reproduction of the sound that you're hearing that end up in the audible range.

Assuming that there is, in fact, 50% more traffic that needs to flow.

So it’s about resistance? The mains cable is sufficiently conductive but the bell wires isn’t?

'Impedance,' but yeah, pretty much. If bigger is better would you hook up speakers with the cables they string pylons together with? Surely that'd sound surfmat-levels of awesome!!

Doesn’t make sense to me.

Then I'm not sure as I've got anything else.

Basically, it's diminishing returns. There comes a point where you're either not adding anything or are adding so little that it's a fool's errand. It's the latter bit which muddies the waters, means there's no single discrete cut-off and empowers AV companies to flog £1k power cables. Analogue by definition is shades of grey.

Yeah, volume, sound pressure, plays a big part, I need to increase a good bit to even hear the 13k sine. I can push it to 15k at very high volumes and just about hear something, but tbh, I'm a bit reluctant to do that for very long, no idea if it causes damage!

I downloaded and had a wee play around, seems, ok on the sine wav that, but there's an awful lot of distortion and extra noise on the square and saw tooth though, so I wouldn't really be trusting anything there.

I tried what you said, made a 2 note chord with 2 of the oscillators on sine and put the 3rd up beyond my hearing range, tbh I never really heard it making any difference to the dyad. could hear a bit of notchiness for turning the dial, but that was all, until the audible sound came back in to make it a triad.

It really isn't, unless you're arguing semantics over 'point' to mean a quantifiable absolute rather than "at some point."

Say I'm building a house and I've got free reign over a new front door. I'm 5'10". How high do I make the door? Your discrete "point" here is 5'10", but is that an ideal choice, do I want to be just skimming my way in every day? Does that account for occasional peak visitors who might be 6'5"? Or, I could get away with a door a metre high, it'd be functional but it'd be an uncomfortable compromise every time I have to slowly stoop / crawl through it. Maybe I should cover any eventuality and make it three metres high? Well, it'd look good at least, some public buildings such as churches do that sort of thing. Why not half a mile then?

Analogue is not discrete. Shit solutions are shit. But once you broadly approach, reach or exceed "good enough," anything further is just showboating. You're no longer paying for functionality, you're paying for ostentatious pissing rights.

Again the door analogy doesn't work for me as relevant. The item is question is copper wire, not a door, water or traffic. I understand your analogies, I just don't see how they are relevant because you haven't linked them to a copper wire carrying audio AC electricity. The only link is one of some sort of capacity, ie resistance (you said impedance, sure, but inductance and capacitance aren't affecting audio frequencies in the cable as much).

Unless I have misunderstood, the bell wire doesn't sound good enough for you? You originally said bell wire wasn't up to the job but mains cable is as good as anyone needs and nothing else is any better.

Bell wire seems to be 0.5mm², copper has a resistance of 0.0171 mm²/m. So a 3m run of bell wire is 0.2052 ohms there and back, against nominal 8 ohms of drive unit impedance. Mains cable is 2.5mm², so 0.08208 ohms. Voltage drops of 2.5 and 1% respectively to an 8 ohm load (which varies from say 6 ohms to much higher over the spectrum). Around 0.1dB.

Can you explain using physics why mains cable vs bell wire makes the difference you say it does?...and why nothing over 2.5mm² will.have any benefit?

I had Mission 733 floorstanders with a cavity for mass-loading at the bottom, you poured in a bucket of special acoustic metal (swarf) and the increased weight made the speakers sound a bit tighter

I had a set of those. Still regret selling them - they really did sound great for the money

Cheap builders sand does just as good 🙂

you need it properly dry. Childrens play sand went in mine.

Interesting. I can't hear much above 12 (a little bit further if I turn it up). Our cat, who is pretty much deaf now, woke up downstairs and started shouting though so seems she may have lost all the lower frequencies but not the very high....

If I've not got anywhere by this point then no, I can't.

And honestly, it's a reasonable question to ask, but it's beyond my knowledge to field I'm afraid.

anecdote time. I ran my half decent system on bell wire then mains - the difference in sound was obvious. I then put proper but basic speaker wire on. I am sure I could hear a difference but very hard to be sure

I thought that, but then I realised that the outer knobs move the frequency by smaller amounts, and you can clearly hear the sounds coming in and out of phase i.e. beats. So I think the funny noises you hear are the beats of the square wave interference creating waves in the audible spectrum. Given that the kit seems to be able to reproduce sounds at high frequencies it does rather suggest that you can make audible frequencies out of multiple inaudible frequencies. Ok so in this case it's not a pleasant sound, but it demonstrates the principle.

https://en.wikipedia.org/wiki/Skin_effect

Carriage of AC frequencies is geometry (but not really material) dependent. Copper or silver wires will have the same effect. Thickness matters up to a point. Length less so. Skin depth for 10 KHz is 652 uM, so a decent cable thicker than a couple of mm diameter will certainly perform better than a very thin one over the audible range.

Thanks Cougar, I understand what you are saying, and your explanation, but it’s the scientific answer that matters to me.

@cynical-al

From the context of power transmission (but it's the exact same principle)

High transmission voltages allow the use of a thinner wire for a given power (since the current and associated resistive losses are lower) therefore for a set voltage more power requires a bigger cable (since there is a corresponding increase in current). The power transmitted in a cable is equal to V × I but the transmission loss is proportional to the square of the current (3.I^2.R). Now you can decrease the resistance of the cable by decreasing the current, shortening it or (for our argument) making it bigger. Obviously that works but after a certain point you hot the law of diminishing returns since the power loss would be so marginal.

So why are "audio" cables a load of crap? Well, look at this and tell me it's not twin core? https://www.richersounds.com/hi-fi/hi-fi-accessories/speaker-cables/audioquest-terminated-5m-pair-of-speaker-cables.html
Copper is copper, the resistance may vary slightly but a signal doesn't give the slightest shit so long as it gets to its destination without outside interference. This isn't the bounds of known science, this is solid known science and to be honest I'm pretty disappointed that even needs to be said.

Copper isn't just copper, it can have lots of impurities in it, and it's also (like all metals) crystalline which means it has crystal boundaries in it. These things affect electron paths through the solid.

Of course it does, but not in any meaningful way as far as we are concerned.

[url=file:///C:/Users/hu03042/Downloads/bs6004-624y-twin-and-earth-pvc-cable.pdf]Here[/url] is an example of some twin and earth. Note the conformance to EN 60228.

Now what does that mean? [url= https://www.elandcables.com/company/news-and-events/why-copper-purity-matters ]Here[/url] you go.

So yes, it can have "lots of impurities" in it. But if it does it's shite, which we have all agreed isn't worth using.

To add, that document lists the resistance value of 1.5mm^2 cable as 12.1 ohms/km. That's 0.0121 ohms per metre, less than a six hundredth of the resistance inside your speaker. If you're really concerned you could go with Cougars 2.5mm^2 cable for a 0.00741 ohm per metre drop.

Good job we have international standards for these things. Like I said, this isn't cutting edge fringe science.

Cheers @Squirrelking I understand voltage/power etc (see my prev post, I calculated a power loss of 0.1dB between the cables) and I don't feel you have answered my Q. Cheers TiRed - I'll look into that, I knew all this stuff a couple of decades ago!

What this tells me is that no one knows the answer to this, some on both sides believe passionately (moreso the naysaysers is seems) but no one can prove either way.

As mentioned by a pp, I think it’s quite telling that by and large, audio professionals don’t buy into all this. Of course they’re not using complete crap but they’re not generally using stuff that costs hundreds or thousands a metre. And these are people who often have systems that cost house type money.

There was a long discussion on this on GS and the conclusion (apart from snake oil) was that different cables can make a tiny difference, but that difference wasn’t actually better or worse. Just different.

Personally I think about 2% of system budget is about right. Op looks like he’s spending about a grand so about £20 is appropriate. Any higher than that you will be better off spending on the source components, as you stand a far better chance of being able to actually perceive any improvement.

Well I don't know how else to answer it. Those are the facts so either you don't really understand or you're not asking the right question.

What this tells me is that no one knows the answer to this, some on both sides believe passionately (moreso the naysaysers is seems) but no one can prove either way.

And that's just crap. I'm not an electrical engineer, far from it but we're talking about fairly elementary stuff for those who are. This is their bread and butter, how else do you think cables get specced for specific purposes?

I can't believe it has taken 214 posts to say NO.

I am really glad that fools fall for this bunkem as it makes the world go round and creates jobs. If everyone could critically think then most markets would collapse.

@squirrelking, I should have/meant to say

no one here can prove either way.

And 5plusn8 it's been said from the first page. You are making me giggle with your last sentences tho - you think the same doesn't apply to the bike market?

I know that, I'm not claiming to be the first. My point is: it is on 214 comments and the answer is still no.
I don't think the bike market is any different, that's the point of my last sentence, I wonder if your comprehension skills need a tune up? Maybe that's why you think fancy cables make a difference. As I said, most markets would collapse if we were not so stupid, why would that not include the bike market?

Of course it does, but not in any meaningful way as far as we are concerned.

Well, I'm no audiophile (I do own a hifi with separates but it cost a few hundred quid and is 20 years old), but I think I should correct that sentence - not in any meaninful way as far as YOU are concerned.

You are providing us with calculations, which is fine, but you are not demonstrating that you are calculating the things that actually affect perception of music in certain people's minds. Of course you'll scoff and say something about placebo here, which isn't necessary as we're all aware of this effect, but despite your contributions I am still not seeing enough science here when it comes to hifi audio. It's a complex area and I'm not sure it has been fully explored even by the scientific community.

Correct and that sums up the main point about audio/hi-fi. It is highly subjective. Hence why some prefer vinyl over digital or valves over solid state. If you prefer the sound of something that's the one you think is right, even if it's highly inaccurate (which it often is).

I'd still love to see a proof, @5plusn8 where did I say I liked fancy cables? Maybe brush up on your own comprehension, or reading skills? @squirrelking I get that you are frustrated but I really don't see what you have proved.

Does speaker cable actually make a difference?

Yes, it does.

My point and I'm sure it's pretty clear, is that this is what happens to any sport/pastime/hobby when middle aged men with disposable income happen upon it.

They spoil it.

See also golf, mountain biking, road biking, cookery and so on...

so, if you like Pina Colada, getting caught in the rain...

True, but no-one can be bothered, it's expensive, and it's not in certain parties' interests, is it? 🙂

I'm not saying that £100/m cable is better than £50/m cable. I'm highly sceptical of that. But I noticed a difference with £5/m cable. But the people who make the £5/m cable also make much more expensive cable, so they're not going to debunk that myth are they? Even if it's true that £5/m cable is better than £1/m cable or mains wire.

Why does the presence of rich middle aged people spoil MTBing? I think they fund development for everyone else. On Saturday I saw loads of MTBers out, from middle aged men to young lads, all filthy so clearly having ridden the local gnar. The kids were on decent looking bikes, probably budget models trickled down from the expensive stuff. All were having fun. All keeping the cheeky trails open with wheel traffic too.

Fair enough I haven't actually read any of your posts, I only skimmed the thread, but I did read your replies to me and obvs made the wrong assumption...

Not allowed; Mrs Crikey needs guidance while making her latest sewing creation!

But they spoil it because it changes the emphasis from the activity to the kit required. It happened in the running world when I was 15; all of a sudden you were judged on your trainers instead of your performance. Same goes for mountain biking; what's the 'entry price' to it now?

Then we end up here with people arguing about the kit instead of the music.

This is what makes playing around with a home setup so interesting. Its about enjoying the music.

Accurate monitoring setups are tools for the audio industry, they don't sound bad, but they can be a bit boring to listen to.

In their minds, maybe. However MTBing has always been strongly kit related, because it's an aspect of cycling that demands particular kit - fat tyres etc.

And hi-fi has always been ONLY about kit. It's not really anything to do with music, which (in case we've forgotten) is about artistry and creativity.

Re the Soundguys article, they seem to take a lot of nice accurate measurements, see differences, and then hand-wave them away with stuff like this:

Only at 10kHz does the deviation cross the threshold of audibility, and even then: that’s a very narrow range of sound that will absolutely get lost in music. You will not be able to tell unless you’re a child prodigy and have been trained to know what to look for.

Can they prove that these deviations 'will get lost in music' ? What music? Whose ears? How many latent child prodigies are out there? How many have trained themselves to listen out?

Lots of questions. It is entirely possible that we're not yet aware of how the complex signals in music interact with our brains.

I've no idea why I can't bear to listen to MP3 music on headphones for long periods, but I can listen to HD audio (on Amazon) all day.

this whole thread just reminded me of a chap I know who recently bought some very high end speakers to go with his high end amp - and for a source he uses youtube which IIRC is a compressed / fiddled with source!
