What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

KEF K 120

The very first KEF compact speaker, in 1961 was the K1, a three-way baffle available in several formats. Since than, an honourable tradition of music related "C" series names has held sway. In this thirtieth anniversary year, the initial "K" returns to identify three models, each of which embodies the principles, experience, and tradition learned and earned during the past three decades.
Careful attention to both visual and acoustic design means that the "K" Series models are as easy and attractive to integrate into a home environment as they are capable of reproducing today's sometimes complex and demanding recordings in a lifelike and convincing manner.

The new K-Series models featured an attractive ‘louvred’ baffle, a quality 25mm ferro-fluid cooled tweeter, paper coned bass-midrange drive units for high sensitivity and substantial cabinets. They were carefully designed to offer an easy load to the budget amplifiers they were likely to be partnered with.

K120 (1991-93)
In the design of small loudspeakers every parameter becomes more critical. Only a'complete system' approach, as employed by KEF, is likely to bring success. Careful study of drive units, crossover and enclosure, separately and together, with their interactions, is the means to produce a musically integrated sound. KEF system design techniques have , in the K 120, produced a supremely musical small box, designed to produce its specified response when operated on a shelf, or stand mounted close to a wall.

The K 120 is a compact two-way speaker which sounds much larger than it looks. The lightweight 160 mm (6,5") bass/midrange unit provides uncoloured, fast bass response, whilst the 25 mm 91") fluid-cooled tweeter offers accurate, uncompressed high-frequency performance of exceptional clarity. A deeper-than-average cabinet gives an internal volume, and therefore a bass performance that belies its compact frontal aspect. Ideal for a first or second system, an audio-visual installation, or as satellites for a subwoofer, the K 120 is a truly outstanding miniature.
