The story has a villain: the room. The K6 is a story of physics. They need to breathe. I pulled them 4 feet into the room, toed in just two degrees. In my 6x8 meter room, they disappeared. The soundstage wasn't between the speakers; it was a dome from the floor to the ceiling, wrapping around the listening chair.
The Setup It was a damp Tuesday in Cheshire. The usual suspects were in the listening room: a Naim ND555 streamer, two gargantuan Statement amplifiers, and cables that cost more than a used car. The speakers they were replacing were no slouches—venerable Wilson Watt/Puppies. But curiosity about ProAc’s flagship K6 had been gnawing at me for months. proac k6 review
This is the K6’s trick. It doesn’t fabricate bass; it uncovers it. The twin 6.5-inch drivers are not for volume; they are for velocity . The bass line didn't thud against the walls; it flowed under the floorboards, deep and textured. I realized the Wilsons had been lying to me about the shape of that note. The ProAcs told the truth: it was round, not square. The story has a villain: the room
You could hear the echo of the Ryman Auditorium’s wooden pews. You could hear the sweat on his fretboard. The K6 has a "family sound" of alacrity and rhythmic snap, but the K6 adds a layer of density to the midrange that the smaller ProAcs (like the D2R) lack. It is brutally fast, but never thin.

My first reaction was confusion. Where was the bass? The Wilsons had punched me in the chest. The K6, initially, felt polite. I almost dismissed them. But then, 90 seconds into the track, the descending synth bass note hit. It didn’t punch—it materialized .
