Started building speakers in high school for personal use and even sold a few. Developed interest in planar magnetic types and started making my own designs. Published two articles in Speaker Builder 1995/1996 (magazine no longer published). Planar driver is of my own design and manufacture which consists of magnet structure and suspended mylar diaphragm with laminated conductors. Driver can be crossed over as low as 300Hz and has wide horizontal but narrow vertical dispersion.
