Dave helped me tremendously over the past year with crossover design, unibox lessons, and just lots of e-mails to assist me as I built a pair of 3-ways. I haven't received any e-mail responses from him in the past month as I finally finished the project and sent him pics. That isn't like Dave not to respond. Does anyone know what has happened to him? I'm worried about him as he has always been interested and responsive to e-mails regarding the speakers as they moved from a dream to being complete. Anyone able to provide any info about him?
