There is a pair of these on EBay.
Has anyone on this Forum ever come across them in the past?
They utilise a Wharfedale Super 8 RS/DD driver and a sealed back ELAC tweeter. The crossovers appears to consist of a single capacitor and potentiometer to adjust the balance between the drive units.

I am intrigued ( and slightly tempted ) by them, as I collect old/vintage loudspeakers. I'm currently refurbishing a pair of Radford Bookshelf speakers.
