Hi,
How do i connect speakers?
In my setup core and mm's are centralised. Distance from most distand speaker to the closet is 25 meters.
I have read speaker cable runs that exeed 15 m degrades sound quality.
What are my options?

I have cable runs of 30m with 4sqmm cables, and do not hear a problem. And no, I do not have a centralized setup, but it is a long way from ground floor, through the basement to the attic above the ground floor to make sure I do not see nor hear the MD.

The reason sound quality degrades in speaker cable in this fashion is due to increased resistance. Resistance can increase due to smaller diameters, and/or longer lengths. There are other factors, but those are the main ones.

So yes there may well be a limit of 15 m, but only for a certain diameter of cable. A larger diameter of cable such as possy is using will combat the problem.

Cheers,
Matt.

Good article about speaker wire.
Conclusion: allthough not ideal, cable runs that are 25m for 4 ohm speaker requires  an AWG of 10.
