KEF C10 Bookshelf speakers review
Bookshelf speakers KEF C10

The C10, the smallest of the series, and the C20, the next up, are both intended to be used against a wall or on a shelf; they have a deliberate step in their frequency response to equalize the results when so placed in what KEF have termed the 'boundary' condition. The free support at low frequencies...
KEF C15 Bookshelf speakers review
Bookshelf speakers KEF C15

The pint-sized C15 is a straightforward two-way system with tweeter, main driver and polyester damping material crammed into a closed box of only 3.5 litres internal volume. None the less the components and construction are of good quality and the claimed performance is a real improvement over run-of-the-mill...
KEF C20 Bookshelf speakers review
Bookshelf speakers KEF C20

The C20 can accommodate a larger B200 (185mm cone) drive unit in its larger cabinet. The free-air resonance now drops to 35Hz, taking the low frequency response down about half an octave below the C10. The crossover, still at around 2.8kHz, uses two additional components to form a flattish, series-resonant...
KEF C25 Bookshelf speakers review
Bookshelf speakers KEF C25

Moving up from C15 to the C25, we find an internal volume increase from 3.5 to 6.8 litres and marginal specification increases under all headings: sensitivity up to 87dB, power handling up to 70 Watts and maximum SPL 106dB. Apart from the larger enclosure, all the beefing up of performance can be attributed...
KEF C3 Bookshelf speakers review
Bookshelf speakers KEF C3

For its sizes KEF C3 monitors are quite massive. They are designed by two-way scheme with slotted bass-reflex on the front.

KEF C30 Bookshelf speakers review
Bookshelf speakers KEF C30

The C30 is meant to be used out in the room on a 25cm stand. The cabinet is larger and KEF have chosen to place this B200 unit's free air resonance at 45Hz. The crossover remains similar but the series capacitor is omitted. As KEF perhaps intended, this loudspeaker sounds much like the C20 but does not...
KEF C4 Subwoofer review
Subwoofer KEF C4

The appearance of KEF C4 sbuwoofer is moderately conservative, only frontal slotted bass-reflex outlooks on the body with classical sizes. Low-frequency driver here is of 8 inches (200 mm), the amplifier is also not the most powerful, but 200 W for usual living room will be enough. The body is assembled...
KEF C40 Bookshelf speakers review
Bookshelf speakers KEF C40

On then to the C40, a logical successor to the Carina, with a second B200 unit operating at low frequencies only. These two 3-ohm B200s have a free-air resonance of 40Hz. The two together, connected in series to give 6 ohms and shunted by capacitors of 10μ and 100μF respectively, produce a resonant...
