I just found a picture with the edge connector showing - you would need a 2 pin DIN plug at each end of the speaker cable.  If you'd prefer to use the centre rear connection, just use 2-pin DIN to bare wire speaker cables.  Steve at Sounds Heavenly sells suitable cables but his site is down at the moment. 

Super. Thank's for the help.

I just looked at this Beomaster 5500 today at a seller and saw the DIN connections in the Beomaster and for nervous that the RL speakers could not be connected.

I do believe that you can connect the RL speakers to almost any brand amplifier and the RL speakers have ordinary cable out-puts. 

The RL60's (I assume the 60.2 are the same but not sure) have push-to-open sprung loaded bare wire connectors in the recess where they connect to the floor stands, as well as the din connector at the periphery. Connecting to the din connectors looks nice when you have the original red pinstripe curly cable but if using normal figure-of-eight stuff id use the rear connections.
