K1 is a stand-mounted two-way passive loudspeaker in the ProAc K Series range, an award winner in the HiFi+ 2021 Stand-Mount Speaker Of The Year category.

Considering it’s size, the ProAc K1 gives an impressive soundstage for a stand-mounted loudspeaker, with an almost electrostatic open midrange and extremely accurate bass.

The premium ProAc K series has now been in production for over a decade. The K3, K6, K8 and most recently the K6 Signature models have proven to have been very popular choices for people looking for the ultimate in sound reproduction. With this success ProAc were asked for a stand-mounted K series loudspeaker – and here it is, the K1.

K1 is a special stand-mounted version using a Kevlar cone (as in the other K-range models) plus the well-proven ribbon tweeter unit. Certain modifications have been made to the cabinet, bass driver and tweeter to make the design adaptable and suitable for a the smaller stature of stand mounted loudspeakers.

The result is a surprisingly extended and accurate bass response, coupled with the usual beautiful midrange from the K-series bass driver. The unique design sees a cabinet which is bottom ported, and a specially-designed dedicated stand to complement and bring out the best in the K1 – available separately, as many people already own stands.

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.
