Hi - thanks for the quick response and welcome.
I think they do look like this, yes. I'm at work at the moment, so will check a bit more thoroughly when I get home, but I think they are the 2 pin din. If it is any help I have attached a couple of photos of the back of the speakers that were sent to me.
Thanks for putting my mind at rest that there are solutions out there! Had quite a panic when I opened up the box!
Mike
