200 Series

203 (1981-85)
The 203 (also known as the Caprice II - the logical successor to the Corelli) offered very good performance at the critical mid-price level. It used the same drivers as the Reference Model 103.2 but with a more basic cabinet and crossover. It continued in the line of high performance but affordable bookshelf loudspeakers offering impressive realism from a compact two-way enclosure. The system could be easily located to give good tonal balance and sharp stereo images in generous sized rooms.
 
The new 8” bass driver used the proven bextrene cone for low colouration and also utilised the new technique of driver decoupling – whereby the chassis is screwed into the cabinet via soft rubber mountings to reduce the transmission of chassis vibrations into the cabinet structure. In common with the majority of KEF’s closed box designs at the time the bass response was tuned to a third-order characteristic by the inclusion of extra components into the crossover network.
 
204 (1981-85)
The 204 (also known as the Carlton II - the top model in the C-Series) was a high quality floor standing loudspeaker intended for use in living rooms of average size with associated electronics giving up to 100 watts output per channel into 8 ohms. It followed on from the Calinda and Reference 104aB in being a two way system of generous internal volume with the bass response extended by the use of a passive radiator.
 
In common with the higher models in the C-Series the bass driver used the proven bextrene cone, which when critically damped and terminated offered a low colouration sound with good consistency in production. The 3kHz crossover to the new T33 fabric domed tweeter followed a computer optimised fourth order acoustic characteristic.
