This is a super cool set of KEF speakers from the late 80s. The immediate successor to the famous Coda III, probably the most successful loudspeaker of its generation, the ‘flat’ balance of the Coda was retained, so this ‘large bookshelf’ speaker was best suited to open stand mounting. However, the polypropylene coned 200mm bass/midrange unit had greater midrange sensitivity and improved bass damping, so shelf mounting was still a perfectly feasible option. C30 provided much of the performance of its more expensive stablemates in a simpler package.
These beauties have seen some love and use but still look and sound great.
