I am a retired mining engineer that worked underground for almost 40 years. I built my first speakers when I was 16. I think it is fair to say that speaker design and passive crossover development is where my passion lies. I have had some nice speakers. Klipschorns, Heresys, Altec Model 19, JBL 100s, AR3, Bozak 302 and about 50 pairs that I built. Most people that know me will complain that I only talk about speakers and fishing. I have spent a lot of time at the Parts Express forum and Diy Audio. I came here to meet some new people and hear some new opinions. I hope that I can add something to the mix. Howard Stever
