OK, if one was to say use google.co.uk and search in the UK for "Harmon Kardon 695" then one might be rewarded...
which is where I got mine...
They are DELL supplied, but are the same spec as the more expensive ones I am sure you might have seen in a high steet. (Although those have solid metal bases.. but are the same speaker... same outpout, same cones, but don;t have the silver meshes the DELL ones do)
They are quite kewl... the right hand speaker ahs two soft buttons on top, for volume up and down... and LED's...
