proac is formed
In 1979 Stewart discovered a better quality range of drive units that were used only by professionals and so he formed a new company called ProAc (an abbreviation of Professional Acoustics). Here is the early production of the ProAc range at Borehamwood

The Response Range is released
An important milestone in compact loudspeaker design pushing the performance boundaries of what a small stand mount speaker could deliver.
A new factory was purchased in Brackley to move production from both Borehamwood and Milton Keynes.
Production is well underway at the new factory in Brackley.

Progressing the Tablette Range

The demand for a home cinema experience is met with the new home cinema set up from ProAc.
Celef/ProAc expands into the next door unit at Brackley, giving more space for research and development and increasing demand for products.

Marketing - ProAc's First Product Guide
All our products in one brochure showcasing the three ranges: the Tablette, Studio and Response Range. The latest models include the Response Tri Tower, D80 and D100.
Use of Carbon Fibre
ProAc continues to experiment with different cone materials and in the new Carbon Pro 8 speaker a unique cone using carbon fibre was introduced (which was quite advanced at the time). The Carbon Series went on to include the smaller Carbon Pro 6 model.
Introducing the K Series
The K6 is released, named due to the cone of the woofer being made from Kevlar. Kevlar is an excellent material for producing exceptional bass response.
K Series expands
The new K8 is introduced. Here it is in silk white along with the Carbon Pro's at the factory in Brackley.
The Response Range Grows

Celebrating 40 Years
2019 is a landmark year for ProAc as it celebrates its 40th Anniversary.
Following the discontinuation of the K8, the new awesome K10 is launched at the Bristol Sound and Vision Show. Alongside it, is the award-winning K1, the first stand-mounted K series speaker with a dedicated stand.
The whole ProAc family is devastated by the sudden loss of founder Stewart Tyler. Frances, Zoe, John, Tristan and the whole ProAc team who have all worked with Stewart and the ProAc brand over the last 30 years, vow to take the brand forward and honour Stewart’s legacy…
The UK Audio Show
The ProAc journey continues as we take part in the UK Audio Show's Hall of Fame programme. We hold a special retrospective exhibition of early speaker models, old photos, hi-fi show posters and brochures. Zoe also gives a presentation, telling the story of how ProAc started, from a small unassuming hi-fi shop to a busy manufacturing factory with global distribution.
"The thought of achieving a loudspeaker that can fool you into believing you are listening to the real thing is the first thing in a designer's mind."
