Looking at installing ceiling Atmos speakers and I wondered if anyone had managed to have speaker wires on the ceiling yet not stand out like a sore thumb and be wife/partner friendly? Speakers would be a metre from the walls edge.
You'll struggle to be honest. It all depends on the type of ceiling you have.
Is it plasterboard, wood or concrete?
You can get flat speaker cable although the weight of the cable, however small, will cause it to naturally sag which will require you to use more clips which will, of course, make it more visible.
That's if you intend to clip it direct to the surface.
The other alternative is mini trunking but this option will make it even more visible.
Even the D Line spec trunking which is semi-circular will stand out like a sore thumb if not done right.
Surface mounting as opposed to recessed is always a compromise.
