Can I get extra pair of speakers with required wireings

Solution
It seems that the speaker connectors on the Samsung accept standard bare wire speaker cable so you can use any speakers and purchase enough 2 conductor speaker wire for the lengths you need. If the wire is too thick for the holes when you push the button in it's fine to thin the last bit of wire so it fits.
