The Calinda
three-way loudspeakers are among the first KEF model to benefit from the
technological innovations introduced by the Company during the early and mid
1970s - in particular the application of computer-based test methods in both
design and quantity production and the use of the "Target Function
Concept" in the synthesis of crossover networks. These advances have made
it possible to produce loudspeakers in the domestic size and price range with a
standard of performance hithero associated with professional equipment. Like
most other loudspeaker, Calinda have been designed to meet aesthetic
requirements imposed on them as articles of furniture, and as a result, the
outward appearance shows no sign of their special technical features.
Howev,
with the grille covers removed, as shown above, certain differences in the type
and positioning of the drive units, and it will also be noticed that in Calinda
and largest KEF Cantata, the conventional placing of the mid-range and
high-frequency units is reversed.
These
features, the reason for which may not be immediately clear, are in fact part
of an overall system-engineering approach, in which the various components of
each model - drive units, enclosures and filter networks - are developed
together and optimised to fulfil a particular need; both designs are based on
practical considerations of performance and cost-effectiveness, avoiding the
kind of over-specification that may look impressive on paper but is irrelevant
to the listeners requirements.
Calinda was
an 8 inch two-way system with an auxiliary (passive) radiator augmenting the
low frequency response. This format was used previously in the Cadenza and
Reference 104. In the Calinda system the driver layout was adjusted to allow an
elegantly slim floor standing cabinet.
