Cable For Sonos Play1
Posted 20 April 2016 - 09:10 PM
I was planning to run 0.75mm2 two core flex to each of my Sonos Play 1 from my plant room, which is about 24m run in the worst case. I know the current rating is fine for the cable but I'm worried about the volts drop on such long runs. I have spoken to the Sparks signing off the electrics about it and they said 'it's fine, well within the limits' but they never think about volt drops, they just work on rule of thumbs.
Is 0.75mm2 a little light over that distance?

@Jeremy, these are amplified speakers

Thanks Nick, I'd not realised this. The ceiling speakers I've fitted had a separate bluetooth amplifier box, with leads to the speakers, and the wall speakers all have cables in the walls run back to a media wiring panel.

Fwiw, I would always run a minimum of 1.5mm2 OFC but I typically wouldn't run less than 2.5mm, especially over more than a couple of metres.
Using too big a cable can steal high end frequency so unless it's between an amplifier and a subwoofer don't go higher than 2.5mm2.
