My main mentors later on include Malcolm Jones from KEF and latterly Falcon Acoustics before he retired a number of years ago.
Malcolm really helped me when
I started building my own self designed loudspeakers from about aged 13, a bit later when aged
about 15-16 he taught me a great deal more about crossover design and bass
alignments, this when we used to meet together at Astronomical society meetings
near Norwich.
He became a good friend as a result of our two common interests and I then helped him with telescopes!! Which I designed and built more then than now..
Then from the mid-80s when at college, I can add Martin Colloms, and Chris Bryant when I started getting real serious with designing more of my own loudspeakers, writing and research.
