I stumbled across a pair of Lowther speakers, apparently they are these Bicor 200. The drivers are in a bad state. One is dead, with probably a burnt-out coil and deteriorated surround. The other works, but the surround has been replaced by some fabric. The baskets are quite raw aluminium and are unfinished. Boxes are well-built, but can do with a re-finishing. Is it worth the effort and expense trying to restore these? Refurbing the box is no problem, but it looks like the drivers will be costly.
