Compact Field Core Driver Speaker

Does anyone know of a floorstanding compact field core driver speaker approx size 1.00 x 0.30 x 0.25?
What unit of measure are you referring to? Meters?

Not sure what a "field core driver" is. Is that the British equivalent of what would be called a "field coil driver" in the US?

Sorry should read field coil.
Units are meters.
