About us


Our journey

Allegro Acoustics was founded by David Cawley in 2010 as a specialist acoustic design consultancy. We immediately got stuck in at the deep end taking on the €50m Student Centre in UCD! With a team of just two by the end of 2012, Allegro Acoustics was developing a strong profile for acoustic design in acoustically critical and complex projects in construction and power generation in particular.

Rapid Growth

By 2016, the Allegro Acoustics team was growing rapidly and we had expanded our services into industry with new clients in the pharma, biomed, power generation and manufacturing sectors. With this development came a major step in the digitisation of our services and technology development whereby we upgraded much of the systems we use to automate our processes. Easier said than done!


Following developmental work Allegro Acoustics had carried out in the audio technology space, we launched our first spin off in 2019! ONESONIC Audio Technologies was born – Irelands first and only audio tech brand! ONESONIC is fast becoming a European leader in the audio hardware space with sound quality being a hallmark of the brand – thanks to the audio R&D strengths developed at Allegro Acoustics over the years!

Fitout & AV

With a team of 13 and an extensive list of large and complicated capital projects under its belt, Allegro Acoustics launched the Fitout & AV division in 2022. This division brings together all of our experience in acoustic design, material science and technology to deliver bespoke acoustically designed interior spaces in the commercial and hospitality sectors.
