Study these as they form a major part of the description (Generally in good used condition I did notice that the cloth at the back of one has small tare hardly visible see pictures). Fully tested and working they sound great.

The Celeste IV were distinctive for their industrial design, the all-round black grille allowing them to stand out from the conventional square wooden boxes of the time. The mark IV versions were different from the mark IIIs by virtue of the moulded plinth and top caps and a wide selection of coloured grille cloths. The B200 bass drivers for the Celeste IV featured a new three-sided chassis specifically designed to be mechanically isolated from the cabinet - the first example of driver decoupling in the KEF range.

They were also the first KEF bass drivers to use a paper diaphragm - by this time paper diaphragms were being manufactured with good consistency and the lower moving mass contributed to the high sensitivity target for these systems.
