Mellow Acoustics was founded in 2011 by Tim Mellow who felt that hi-fi design had become too complicated and focused on technical specifications, whilst losing sight of what really mattered – the integrity of the sound. Tim Mellow is an electronics and acoustics engineer with 35 years of experience working at several companies including 12 years at Nokia. His OTL tube amplifier design published in the 2010 issue of AudioXpress has proved a popular DIY project. Tim is also the co-author of an updated version of Leo Beranek’s classic 1954 book ‘Acoustics’ and has published 11 papers in the Journal of the Acoustical Society of America, which can be accessed using this link. Tim presented a paper on his Oscillating Sphere Concept, to the 144th Convention of the Audio Engineering Society in Milan 2018, which he developed while designing FrontRo.
