Soundbar satelite speakers wire diffrence

[Kamranbites]

Recently I purchased a 5.1 soundbar setup, and while everything is set up well, I've encountered a situation where one of the satellite speakers needs more cable length. Currently the satellite speakers are directly connected to the soundbar using an AV cable. To address this, I'm considering extending the cable length using an AV cable extension, with a length of around 5 meters.

 

I am  wondering if this extension might introduce any issues like sound delay or imbalance. The satellite speakers have an RMS power of 80W each. If anyone has a better solution or suggestion, I'm open to hearing it. Thank you!

 

And also the quality of extension wire matters much or can I use any normal quality one.

Unless you are running it hundreds of feet further away, the additional latency will be imperceptible.

Ohhh then good, i was thinking to buy one more 5meter cable to balance it, but as you said there is not much difference then I think it is ok.

And what about the cable quality does it matter should I go with High quality one or normal.

electric fields move at roughly the speed of light. The speed of sound is around 1 million times slower vs the speed of electricity. 1 cm of speaker movement matters more than 1 km of wire distance (for signal delay; signal degradation would be an issue without absurd equipment). 

In computer networking the rule of thumb is that 1 foot means 1 nanosecond of delay (1 meter is around 3ns). If you add an extra 100 meters that's 300ns. 

100 meters = 0.0003 milliseconds delay. 
Generally it's hard to tell if there's a 0.1ms time difference. You moving your head a few cm would matter a lot more. 

Also, in theory your receiver and measurement microphone would adjust time offsets for each speaker.

As an FYI a lot of the questions you've asked are addressed by info in an intro level physics course.

You'd want to look at things related to electricity, waves and sound. This includes currents, resistors, series vs parallel, etc.  Mostly 17-19, 25-37 and maybe 39.

Cables that are totally crap might introduce some problems like interference due to bad shielding or when they only contain trace amounts of copper or other conductive materials due to the bad ground connection. Also the mechanical quality of the connector matters because of its reliability. But in your application all of this matters only if you have a really bad and cheap cable. Everything that is not really bad is really good enough.
