The
K 140 (1991-1993)
was a direct descendent of the Coda II, III, IV which
was a hugely successful loudspeaker both in the UK and abroad. A two-way system
for use on a bookshelf or on stands, the K140 used a 200mm (8-inch) bass driver
to provide good bass performance and high output capability but was compact
enough to fit neatly into a wide range of listening rooms.
KEF have an
enviable track record when it comes to designing classic 200 mm (8-inch)
two-way systems. The K 140 is no exception. Easily accommodated, and with no
special installation problems, the K 140 has a prodigious that is, for such a
compact speaker.
An 18 mm
(0,75-inch) thickenclosure ensures low levels of cabinet colouration, and fast,
detailed bass performance, with good weight and extension, when correctly
positioned. This may be on a stand around 450 mm (18-inch) high, free-standing,
or with some wall reinforcement. The 89 dB/2,83V/1m sensitivity ensures high
output from moderately-powered amplifiers. The use of kapton for the bass
unit's voice-coil former gives high efficiency with low distortion, thanks to
its freedom from magnetic effectc and eddy current losses. Being thermally
inert, it is well able to withstand the high temperatures generated during
high-level replay. Careful equalisation using computer optimisation together
with attracyive appearance, make the K 140 the system of choice for a
thoroughly musical and outstanding all-round performance.
