Which surround sound speaker cable ?

Hi,

Just renovating and need to run speaker cable to two ceiling speakers and two rear speakers, total length of the cabling is 45m.

It is being run in ceilings, dot and dab and studs, wanted a low smoke, zero halogen cable and was recommended Chord Company LeylineX but when looked at £5 per metre pretty damn expensive, I stumbled across QED QX16/2 LSZH at 88p per metre - mmmm !

I am splashing out on some decent monitor audio rear & ceiling speakers and just wandering how much difference there is in quality between the two cables, will be running them from a Denon AVC-X3700H or possibly the 4700.

Any thoughts greatly appreciated as £225 versus £39.60 is quite the jump and wander if would ever notice the difference,

Many thanks,

Lawrence

2x2.5mm cable is usually fine for most Residential projects - some folk will go with 2x1.5mm for surrounds to keep the budget under control, though you have to be careful with how long your longest cable runs can be if you have power hungry surround speakers and long cable runs (10m+).

Many 'HiFi' loudspeaker cables use a 'shotgun' 0-0 layout with the conductors side by side and a central divider, that can be tricky to work with if you are making lots of turns.

Twin axial loudspeaker cable '0' with the conductors twisted around each other in a singe outer is easier to work with for installations.

Decent and consistent copper purity, and the correct cross sectional area of copper is about as much metallurgy and you need to worry about :)

Thanks for detailed reply guess given they both have same 16/2 naming then assuming they are same thickness (I am new to all of this) and down to the quality of the copper - the chord product says 'tin-plated Oxygen Free Copper for low corrosion and low loss over long lengths' where the QED one says 'Using a large cross-section of high purity copper' - guess the chord one is better based on the 5x price difference, just not sure can justify that. The rear speakers are on a 9m run - do you think would notice any difference if went with the cheaper QED cable ?

Many thanks,

'guess the chord one is better based on the 5x price difference' - someone in marketing def hoped so :)

For a 9m run unless you are planning to use big amplification and inefficient surround speakers any 2x1.5mm cable will suffice and don't get bogged down in spurious claims about all manner of nonsense about copper cables.
