KEF K140 stand speakers - dark grey :
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 soundscape, that is, for such a compact speaker
An 18 mm (0.75-inch) thick enclosure 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 equalization using computer optimization together with attracyive appearance, make the K 140 the system of choice for a thoroughly musical and outstanding all-round performance
