Explanation of cable spec (newbie question)


Standard Member
I am looking at buying some long runs of speaker cable, and I'm not sure that I can afford good quality cable.

What I'm after is an explanation of the technical spec of cable

Conductors 2 x 1.5mm2
Inner conductors 189 x 0.10mm(27 / 7 / 0.10mm)

Does this mean that it consists of 189 individual strands twisted into 27 bundles of 7 strands that are then twisted together?? (educated guess)

And would these specs be suitable for rear speakers with 8m lengths?

The conductor size in mm2 is the cross sectional area of the cable, 1.5mm2 is the same cross section as used on a house wiring lighting ring.

189 x 0.10 is 189 strands of 0.1mm diameter.

27/7/0.1 as you suggest is the bundling, although I think it is the other way around, 7 bundles of 27 strands etc.

What output power are you delivering to your rear speakers? It would be fine for most systems.

Thanks for that :)

I am getting a yamaha htr-5640 which give 110w per channel.
The speakers will be mission M71i but they won't be pushed too hard!

I have been trying to read the stacks of material available on speaker cable (theres plenty of it!), and figure that for now (with a limited budget) that this sort of cable will suffice, and with more knowledge, experience and money! I will look at upgrading in the future.
