We’ve all become used to sacrificing sound quality in favour of mobility, accessibility and whatever else makes listening to the music we love easier. But every now and then you just want to really listen to it. Enter the ProAc K6 Signature Series.
To give an overview, the K6 Signature is a tower speaker with a slim design making it suitable for use in the home or studio, housed in an attractive wood veneer cabinet. It features two 6.5” studio professional bass drive units, a 3” ProAc soft dome midrange driver and the ProAc ribbon tweeter for high frequencies.
What makes it the optimal loudspeaker for true audio lovers is the fact that each isolated element works together in total harmony. So, let’s break down each individual part of the K6 Signature in detail, starting with those bass drivers.


First and foremost, they feature Kevlar cones, which is actually what gives the K6 its name. Each cone is moulded by hand in ProAc’s UK facility, meaning the quality and attention to detail is as high as possible. Kevlar is both light and rigid, meaning that it has a quick, reliable response to input. For the K6 Signature the bass drivers are located at the top and bottom of the cabinet, providing a clean sound with extended bass.
Then we come to the midrange. In some regards the midrange has one of the toughest jobs in a speaker, helping to bridge the gap between low-mid frequencies. It serves to create a natural sound that feels authentic as opposed to one that feels fragmented. It’s constructed with a billet aluminium wave guide and special vented chamber to the rear.
Getting the high frequencies right in a loudspeaker is vitally important. Nothing will ruin a listening experience faster than a tinny high end or one that’s too piercing. The ProAc ribbon tweeter is a trusted mainstay of the K series with a diaphragm lighter than a human hair and an inbuilt dampening chamber.


Even the cabinet itself plays a role in the audio quality of the K6 Signature. It’s constructed from materials with different thicknesses to help shape the sound. Although largely the idea is to have the casing interfere as little as possible with the sound, and so it’s heavily dampened with bitumen to reduce the amount it can vibrate. Sound, of course, being created by vibrations.
Because looks are also important – and to make sure it aesthetically blends into its environment – the cabinet is available in a number of wood veneer finishes. There’s black ash, mahogany, cherry, walnut, oak and silk white as standard or optional extras in the form of rosewood, ebony and tomo ash. The model pictured here is rosewood.
As the ultra-high end of audio performance, prices start at around £19,000 for a pair. Whether for your home cinema set up, purpose built listening room or studio, ProAc deliver on audiophile dreams.
