You are right, mine should have been 8mm not cm, you should hear a level difference long before you reach half wave.
Perhaps that's why I hate the sound of most CD's. 😀
To me detail are things like ambience, the sound of the box of an acoustic guitar, stage focus....
Tony... voice coil has not too much length, and hold power because it is inside a
magnetic field..if you remove the coil and apply 10 watts it may melt...this does not happens within the range of a magnetic field... inside the magnetic core, the same coil that can melt dissipating 10 watts may hold 100 watts... because inside the magnetic field and because moving, and this cools down because air is surrounding the coil wires.... that thickness may hold more than 10 amperes without melt exposed to the air and subjected to environment temperature if is inside a magnetic field..outside, the varnish will melt and you gonna have a short between coil turns...not more coil after short..resistance is zero.. a short circuit and the coil is not more a coil.
Speaker cables may run for several meters...and several meters means resistance..people want to avoid, as 1 ohms is 1/4 of a 4 ohms speaker...enormous loss you gonna have.... also speaker cables, or wires, if running in paralel will represent capacitance..each copper wire will be a capacitor plate with the plastic core separating them... several meters means several picofarads and even some nanofarads.
Speaker cables are inductors... even beeing streched producing a straigth line.... straigh line is an ilusion..even line is an ilusion, it is a sequence of dots... in our space, under gravity, nothing is really straigth... a straight line painted over the planet earth will be a curve (bent) as planet is curved (corner).
Straight (theorical straight) lines have inductance alike an eliptic coils..so, speaker cable have resistances in series, capacitance in paralel with the speaker and inductance in series with the speaker coil... this seems may disturb a little some amplifiers.

Tony... voice coil has not too much length, and hold power because it is inside a
magnetic field..if you remove the coil and apply 20 to 30 watts of power it may melt...this does not happens within the range of a magnetic field.... 10 times more power is possible because of the cooling movement and because is working inside a magnetic field

Yes the tone will be completely gone at 8mm.
Agreed. But its mostly the producers pushing the loudness war thing (which I guess creates more mastering engineers who are good at crushing things and than mix engeneers start to think there mixes arent punchy enough, and off we go). Which IMO is the biggest problem these days. I would love to hear some mixes before they squash them to death.
thats a wide swath
To me it means hearing the low level sounds under the loud ones, resolution. the higher harmonics of a vocalist, the ambience, the foot pedals on a piano, the ring off of an acoustic guitar under a vocal

it is about the atheists, but since hearing is involved, it has some application to the current debate - I think.

Hi,
Just commenting on the second quote: what's the difference between Andre's answer and yours?
In case you're wondering, there is a difference....
You know, one of the big mistakes when taking a scientific approach to audio is the assumption that every component used to build real gear is actually just what it's supposed to be.
On the other side of the fence a similar mistake is often made just the same in that quite often things are compared that aren't really comparable.
O.K., you can shout again.
Pulled the earplugs and ready to listen to yet another ex cathedra lecture.
Cheers, 😉

Hi,
He has a very good point in answering a question by another poster, Andre.😎

Sorry, not really my intent but some of these 'tests' are relevant for random (average) listeners and then used to 'prove' everybody wrong, since I'm interested in high quality audio, I could care less what is average perception, it's like asking a learner driver to evaluate a racing car.
Also it seems like if you have a basic knowledge of electricity and a website to write about your wisdom, your credibility are at an instant high. Just look for the flaws, you will find them.
I completely agree Andre. It is how the systems handles the subtleties that separates a good system from a great system. The ambience of the recording venue, the sound staging, or lack there of in a recording. The feel of a plucked string, its attack and its decay.
Its very human to have disbelief in experts who say the opposite of what you wanted to hear
Anyway, I just recently had a fellow enthusiast on visit
We listened to some special David Gilmour concerts I have recorded on harddisc, on a cheap digital television receiver
DA converter is probably nothing special
It was quite fun to see his jaw hanging, and I couldnt count how many times he said, OK, OK, OK
Funny thing I personally doesnt notice the sound as being that much special
Well, I do know it is special, but I probably just have got used to this sound, as being natural, its just there when I need it
I just enjoy music, nothing else
Unfortunately, now its working Im getting bored with no need fore improvements
Speakers are sold to a good old friend
On to new projects, cheaper ones, fun ones
And totally naively I expect them to be better
But probably they will just be different
But I hope it will be fun
Im done taking this so seriously
My cables ?
Some are special
Others are of the very cheapest kind
I dont worry much about it any more
As long as it sounds good Im happy

That is what's most important tinitus. It is fun to listen to when you want to listen 🙂
ok, so do we agree that whatever current flows thru the speaker cable flows thru the speaker voice coils?
so how do you optimise the size of the speaker cable, do you have rules of thumb? or do you have mathematical formula to arrive at a certein size of cable?
i ask this because, as Lord Kelvin would put it, if one can not put in numbers, the things that one say, then his knowledge of it is of a meager kind.
@senor carlos,
i understand what you are saying, but current developed accros the voice coils are ultimately dissipated as heat is it not? motor action causes movement of the voice coil assembly connected to the cones thus producing cound.

Well, presumably, you'd want to have your amps located as tight to the speaker as you can- the only thing better than a short cable is no cable at all.
