Hi

Does anyone know where I can get the speaker cable plugs that go into the bottom of the Beolab 14 subwoofer for the satellite speakers.  Its kind of a rectangular black plug that two speaker wires screw into then it plugs into slots on the woofer.  Lost one of them.  Assume B&O will charge me lost for one but wondering if its proprietary or something you can buy elsewhere?

 

Thanks
