Due to the success of the 'K Series’ floor-standing speakers, we were asked to produce a stand-mounted speaker for the range.

And, after years of research and development, we designed the K1.

The K1 stand-mounted speaker uses our specialist Kevlar cone and proven ribbon tweeter, which is used throughout the K Series range. We have however, made certain modifications to the cabinet, bass driver and tweeter to make it adaptable and suitable for a stand-mounted loudspeaker.

Although the K1 is a stand-mounted speaker, it has a surprisingly extended and accurate bass response with the familiar, beautiful midrange from the K Series bass drivers.

The unique K design cabinet, with its vent porting, has been incorporated into the K1 alongside a specially designed dedicated stand to complement and bring out the best in the speaker. The K1 stand is also available separately.

Considering its size, the K1 gives an impressive sound stage for a stand-mounted speaker with an almost electrostatic open midrange and very accurate bass, a characteristic of the K Series range.

We are sure that the K1 will not disappoint.

Overall Score 89/100

Nicely Roasted

The K1 standmounters are distinguished by a captivating midrange that renders voices with organic detail and emotional weight. Combining punchy bass, lively dynamics and precise imaging, they deliver a coherent, fatigue-free musical presentation. Reviewers from What Hi‑Fi? and Audiophilepure praise the speaker’s musicality and clean low-end.

What Hi-Fi?

"ProAc’s K1 offer a deeply satisfying listen with an emotive midrange and musical cohesion that rivals can’t match"

Audiophilepure

"Every time I sat for a listening session with this ProAc, I was struck by its clean-edged directness and the neat, compact shape of the music."

Audiophilepure

"While no one will see the plinth’s bottom surface once the speakers are on stands, it’s a shame that ProAc didn’t cover the base with veneer or give it some other treatment to make it look smarter."

Pros

Exceptionally natural, expressive midrange that gives vocals organic texture and emotional presence.
Surprisingly deep, well-controlled bass for a standmounter with punchy, taut impact on percussion.
Lively dynamics and coherent presentation that reveal musical detail without fatigue.

Cons

Dedicated stands are expensive and the supplied stands can be resonant, often needing mass-loading or upgrades.
Minor cosmetic niggles (unfinished plinth underside and fiddly fixings) that feel out of step at this price.

Bass

90/100

A single 6.5" Kevlar driver and the stated 28Hz response underpin unusually deep, punchy bass for its size. Multiple reviews praise the K1's weight, punch and taut pistonic drive (Billy Cobham notes), and no reviewer says it 'needs a sub' for typical listening; tonal richness is also cited. For its size this is clearly an exceptional low-frequency performance, though rivals may out-muscle it in absolute terms.

Mid

94/100

Reviewers consistently call the midrange the K1's crowning achievement — warm, organic and highly expressive. What Hi‑Fi calls the mid 'class-leading' with voices convincingly textured, and Audiophilepure notes clean-edged directness and musical cohesion, supporting a very high score for timbral accuracy and presence.

Treble

88/100

Tweeter ribbon and rear-chamber damping yield a smooth, airy top end reported as unfussy and non-fatiguing. Reviewers describe the top-end as 'smooth' and balanced with no repeated complaints of sibilance; the result is refined detail without forward brightness.

Soundstage Imaging

88/100

When positioned carefully the K1 images precisely with good width and focus; What Hi‑Fi notes precise imaging though the KEF Reference 1 is more consistent off-axis. Multiple reviewers stress placement sensitivity, so excellent imaging at sweet spot but somewhat dependent on room and toe‑in.

Dynamics

90/100

Speakers deliver impactful macro dynamics and tight microdynamics — reviewers highlight dramatic weight and clean punch on percussion and bass lines. The K1's 90dB sensitivity and quoted amplifier range support lively, expressive performance with good headroom for a stand-mount.

Build Quality

86/100

Overall build is solid and well assembled; What Hi‑Fi calls the build 'as good as the price demands.' Minor cosmetic niggles and exposed/unfinished plinth underside and somewhat resonant supplied stands are noted by Audiophilepure, keeping the score below reference levels.

Features Connectivity

82/100

Passive stand-mount baseline applied (80) with +2 for dedicated split terminals allowing bi-wiring/bi-amping per ProAc spec. No DSP/streaming expected or penalized; dedicated stands sold separately but not counted as included features.

Value for Money

80/100

Reviewers praise musical balance and a spellbinding midrange but note some cosmetic cost-cutting and that rivals may offer more outright muscularity; without an explicit price in the provided data the K1 reads as strong but not a clear 'best in class' bargain.
