The conductors in copper fixed-wiring cable can be bent to an internal radius of 1×D without any trouble, the limiting plasticity is PVC insulation and in the case of Y type multi core cables the jacket. If you want to go super tight in the corners, maybe elastomeric insulation.
At some point I'm going to move my speakers and make shorter cables, for which purpose I have purchased copper armature wire from the art supplies store and appropriately sized silicone rubber sleeving from the silicone rubber sleeving emporium
