Speaker Cable Thickness: Comparing 2.5mm vs 0.33mm for L, R, C & Rear - Impact on Loudness

Question

Is it true that if you have different thicknesses of speaker cables, some speakers can play louder than others. I use 2.5mm for L, R, C and 0.33mm for the rear, or replace the rear with 2.5mm?

mariuszp19 · Answer

This is due to Ohm's law. But if you hear the difference, I don't know. There are those who supposedly hear on the recording what the artist ate before recording

BlackDeath3 · Answer

That's true. The thinner the wire, the greater the resistance. The length of the cable also matters. However, it is unlikely that the thickness of the wire will affect the volume very noticeably. Unless it is very long. Besides, if it is a stereo sound system, you can set it up somewhere so that one speaker sounds a little louder than the other. The cable will reduce its volume a little, and as a result, they will be just as loud.

this is a 5.1 set. I use 6m cables for the rear part, I do not know if the exchange will do anything? Come on I will say that at the beginning I also used the original 0.33mm and after replacing it with 2.5mm there is a completely different sound in the Cinema (dynamics, space, detail). Is it worth exchanging for the back?
I would like to add that the fronts are from the listening session, after measuring 3.4m, and the backs are not evenly spaced from the listener to the seats, right 0.55m, left 0.88m

What is the power of the satellites? in normal 5.1 already 0.75mm2 is enough.

mariuszp19 · Answer

The principle is simple - the thicker the cable, the better. Of course, you have to use common sense here.

Rzuuf · Answer

The human ear reacts to loudness in a logarithmic ratio, and as sound 2 times stronger we hear one that has 10 times more power . The threshold for distinguishing the strength of the sound is the difference in power of -50% / + 100%, which means that only a sound with a power of 2 times greater or 2 times less can be perceived as "different".
If we assume that in the cable going to the loudspeaker we can "imperceptibly" lose 10% of the power, then the cable should have a resistance 10 times lower than the loudspeaker.
For 4? loudspeakers, the cable resistance should be

Yuri68 · Answer

the speakers are 8 ohm. I don't know, so by ear I did tests on films and the fronts play much louder on the same volume and stand further from the listeners than the back, it is probably not the fault of the special effects for the backs because I tested a few films where the backs turned on, how were the effects for them ?
For the test, I even turned all the channels in the receiver loud and turned on a few films and at the same volume the fronts sounded louder than the backs, and I will add that the fronts were 3.4m from me and the rear 0.55m and 0.88m. But for the fronts I use 3, 5m of cables and 6m in the back, only with a different cross-section

Rzuuf · Answer

The same setting of the potentiometer knob does not mean that the output of the receiver is the same voltage (and power). Only the measurement is decisive! For the measurement, the same loudspeaker (or loudspeaker) should be used, and the amplifier should be driven with the same signal (sinusoidal tone or noise).

speakers from the specification and construction (speakers, transducers and power) are the same 4 speakers) front and back. How do I test the noise to check if the loudspeakers are playing, the volume is the same from each loudspeaker, the same as with the pink and white test, because it has such tests on the receiver. And during the screening, it seems to me that the backs sound quieter than the fronts.

Sorry, I wrote from another account, this is my second one because I was unlocked for spelling only now is the wait long

Rzuuf · Answer

Or maybe you can hear sounds coming from the front better than from behind? You can also check the concurrency of the channels: if the amplifiers are in an unbalanced (not bridge) configuration, then turn on the MONO mode and give the noise signal to the input, and by turning the potentiometers you observe what signal appears on the loudspeaker plugged in between the hot outputs of the amplifiers. Ideally, there should be silence, and in reality - it can be different.

Yuri68 · Answer

I can hear well because as I wrote when I sit in the chair and perform a sound test on the speakers, it is just as loud in my ear at all, so I don't think it's the cable's fault. I was wondering if sometimes the surround path (effects) to the rear on DVD movies, BR is sometimes more muted in recordings than the front, or is it so? I have found out that some of them use dipoles or more effective speakers for a better effect on the rear, than on the front.

Did a colleague calibrate the channels in KD? This is where you need to start to set the levels of all connected speakers. More expensive receivers come with a microphone and the appropriate calibration mode that does it for us.

KOCUREK1970 · Answer

Of course it's true - with listening equipment for PLN 200,000. If you have equipment for PLN 2,000 - each cable will be fine: a loss, the profit from it will be such that you will not hear it anywhere - you will gain nothing and you will not lose anything. An ordinary good loudspeaker cable for 2/3 PLN / m will do the trick. Well, unless you are ..... filem - I can't do anything about it here: and the amount of PLN 5,000 per meter of cable may be too low, because the upper parts of the vocal may be less clear ... if you spend only PLN 2,000 per meter of cable - but also the basic condition: listening equipment for heavy money.

Rzuuf · Answer

The rule is: the better the installation component, the less visible it is!
So you will "hear" a poor amplifier (distortions, noise, bandwidth limitation), and no good one!
You will hear a lousy loudspeaker, a good one - no!
You will notice a (very bad) cable, - no good!
In the same way, you will "feel" uncomfortable shoes, and you will not even notice comfortable shoes!

Have you done any audiometric tests? In the chain: amplifier - speaker - ear, the most technically perfect is the amplifier, not the ear!

Hello Minimum 1.5mm2, the thicker the better. Regards

Hello, will the 0.75mm2 x2.5m cable for the 6? 80W (music) / 40W (DIN) column - [this is the manual] appropriate or too thin?

Zbigniew 400 · Answer

After all, you have the correction of individual channels.
Just as the speakers sound quieter and too much cable resistance, too
further positioning of the speakers is also quieter.
The rear speakers and the so-called effective, they usually sound quieter.
