Does wire length matters

Your original question does seem an exaggeration.. so, often it doesn't matter but it can, it depends. Very different runs on each side can slightly affect response balance.

There should be no need to obsess over ordinary small variations.

You could use a thicker conductor on the left channel that's 50 feet.
CU resistance pr square millimeter is 0,0175-8 ohm per meter.

Basically size up your left side conductor so at least the resistance is fairly identical.

There is also the point of capacitance and inductance, but that is hard to have any opinion about without more info / measurements.

It is not very hard to balance if you want to.

If it's 'normal bookshelf speakers Sony' & they are positioned 'in two corners of my hall' then I'd infer that outright sound quality isn't likely to be a major issue / object, & the differences in resistance will almost certainly be swamped by other factors. In those cases, I'd just get the cheaper wire, or some from a local electronics supplier if available & affordable.

The main issue is not with the length but the difference between two channels

One channel runs with just 1 meter 16 awg wire were as the other channel 50ft 14 awg


Points to note
16 awg 1 meter
14 awg 50ft

Thing's possible
Can change 16 awg 1 meter wire to 14 awg 1 metre wire
So atleast the gauge stays same

What do you guys suggest
Or it should be left as is
Thanks

You haven't mentioned exactly what these speakers are, or the exact details of how they are set up. All you've said is that they're Sony branded bookshelf speakers in corners of your hall. That comes with a lot of questions; since we don't know, we have to guess. I may be completely wrong with the following, so apologies if I am. But for what it's worth:
  • Sony have produced some decent speakers in the past, but based on your previous threads, I'm guessing these are probably bookshelf speakers from some kind of mini-system (or similar). If that's the case, outright quality was probably not the design object.
  • They're in corners, and unless the speakers were designed to be used in corners, that's usually a fairly poor location, acoustically
  • We don't know if you use your hallway as a 'living space' as such, where you sit down to listen, or if the speakers are just for providing background music / voice / similar. In the UK, most halls tend to be used more as entrance spaces or corridors than as a lounge or similar, although there are exceptions. Based purely on my own experience though, I'd guess they're meant for background.
Based on the above -'quality' is a bit irrelevant, and worrying about some differences in resistance between the wires to each channel is fairly pointless. You're right in that in some critical cases the differences may be audible, but if those guesses are correct -they either won't be (because they'll be swamped out by, say, poor speaker / amplifier quality, poor positioning etc.) or you simply won't notice or care because on top of that, they're not going to be listened to with extreme care on high-resolution material anyway.

I may be completely wrong in some or all of that. But if you want useful opinions, you need to provide us with more information so we've got a reasonably full idea of the circumstances & details of the system & its setup to go on. That basically means: the exact model of speaker, what the system feeding it is, the size & shape of the hall, the exact positions of the speakers in it, and what you actually use this system for. With that -we can give you a better idea about whether it would be worth making changes to the wire or not.

Yes it matters, especially on that long of a run. The impedance of that long one will probably come close to halving the power delivered. The real resistance can be dealt with by increasing the gauge of the wire but the inductive reactance will be the issue. For that long of a run I would also suggest going with some form of wireless speaker or amplifier. Or, easiest, just use matching lengths of the same cable - you will still have the losses but at least they will be balanced.

Wiki has a simple article that should give you a feel for what the issues are:

Ok this Sony speaker are three way speakers one woofer,tweeter,pizzo tweeter

I use them with tv or sometimes to play songs from phone it's a theatre like sitting tv is in the middle and chairs at middle the hall length is around 50ft

And breath is around 10ft

Bookshelf speakers are on stand 5ft above the ground
As mentioned before they are 100w speaker 3 ohms bass reflex type

But mostly everyone says you might not notice much difference in both channels
So you suggesting me to atleast get same lengths on both sides ?

Thin cable is good!

Resistance minimizes distortion.

See simple resistor method by Esa Merilainen on current drive info website.

Will sound better, just tame bass because of corner placement with smartfone eq app.

Turn 150 by 7 and 250hz by 3db down.

If you were running 8 ohm speakers it would be different, but with the 3 ohm ones it will make a appreciable difference. Of course the easiest thing if you already have the wire is just hook them up temporarily and listen. If it is acceptable just go with what you already have - if not, look into other options. In the end, it is what you are satisfied with that matters.
