K3 is a floor-standing three-way passive loudspeaker in the ProAc K Series range.

For customers who desire music ranging from full orchestral to loud rock, the K3 is an excellent choice with which to deliver the required results – with ease!




Cone material is something that ProAc have been developing over the last fifteen years, with an emphasis on Carbon fibre and Kevlar.

A new Kevlar cone was developed which would work far better into the midrange, which also has the added benefit of a phase plug giving better detail and dispersion.

The new Kevlar drive unit was developed for the K3 loudspeaker, and has excellent weight to the bass as well as good extension with a detailed and uncoloured midrange. Two kevlar drive units are used in the K3, along with a ProAc ribbon tweeter placed centrally.

A high-quality crossover was also specially designed for the K3, seamlessly mating with the ribbon tweeter, using components split for bi-amping and bi-wiring and connected directly to the terminals.

Regarding sound quality, K3 has a wonderfully electrostatic type of midrange, very clear and detailed with a dynamic bass response.

K series

All K series loudspeakers provide beautiful cabinets with beautiful sounds, using cutting-edge technology.

The ProAc K series range of speakers are so-called because Kevlar is used in the construction of their drive units.

So far ProAc have only used Kevlar and Carbon Fibre for the reproduction of bass and lower midrange in large enclosures. K series cones have a light, stiff quality, and the Kevlar has more warmth, thus making excellent bass transients and extension.

Few companies have consistently produced high-quality products which have earned international acclaim, and ProAc is one such company. They do not make cheap loudspeakers and certainly do not produce cheap sounds, and many thousands of audiophiles worldwide happily agree with their philosophy.

Every ProAc loudspeaker is hand-crafted, their technicians individually responsible for the building and testing of each unit. Only the finest components are used, with each new model reflecting the very leading edge of audio technology. ProAc loudspeakers are only available through a network of enlightened dealers - of which Unilet Sound & Vision are one - and we are pleased to demonstrate the products and provide informed advice on partnering equipment.
