These Kef 107 are in excellent shape, the clothe grill covers have been recovered, and the Kube has been fully service by Columbus Radio in winnipeg canada.
This innovative model provided quite outstanding performance with an unusually high degree of user convenience. This was achieved by combining many of the tried and tested Reference Series features with a new concept in active low-level equalisation, KUBE (KEF Universal Bass Equaliser). The result was a unique combination bass extension down to a genuine 20Hz, and good sensitivity, from a surprisingly compact system which is sonically flexible enough to be tailored to its specific surroundings.
Model 107 combined the separate mid/treble enclosure from the 105/2 with the coupled cavity bass loading technique developed for the 104/2 and established itself as one of the world’s finest loudspeakers. The midrange driver was a new polypropylene-coned B110 allowing higher sensitivity with improved strength and durability. As with the 102 and 103/3 the KUBE was an integral part of this system and essential in obtaining its specified performance.
