KEF KIT580w, Brochure & Specs

Uni-Q
KEF's patented driver array, using aerospace materials to allow the tweeter to be mounted at the
acoustic centre of the midrange cone to create a single point source. This is what gives KEF loudspeakers
exceptionally wide dispersion characteristics, with everyone in the room experiencing the same clear,
accurate sound image.
sealed suspension technology
A patented KEF technology that effectively
seals the gap between a moving mid-range cone and tweeter, which has the effect of dramatically improving sound
quality, particularly at higher volumes.
nxt
A flat panel speaker configuration that reproduces sound with a wide directivity pattern without
restricting listeners to a particular 'sweet spot'. This diffuse radiation of sound waves is ideal for reproducing
ambient sound effects.
ace technology
KEF's way of dramatically increasing the effective volume (and therefore
output) of bass driver enclosures by adding granules of activated carbon, whose adsorption characteristics
reduce resistance to each backward movement of the cone. ACE-enabled loudspeakers perform like units up to
three times their size, subjectively as well as objectively.

wireless
Wireless transmission dispenses with running cables across the room to the rear speakers by
using radio waves from a discreet sender unit to transmit the audio signal to a receiver built in to the speaker.
KEF’s high performance wireless system ensures exceptional signal integrity under even the most
demanding conditions.
selecta-mount TM
True to the ease of use that underpins the whole kit concept, SelectaMount
is KEF's ingenious system of concealed brackets designed to simplify wall mounting.

Another KEF innovation, the Bass Extender is a hollow reflex-ported floor stand
whose additional volume helps to enhance bass extension.
