這位似乎就是鼎鼎大名的Linkwitz-Riley filter發明人之一...
一開始就有這麼一段
Most of my involvement with audio has been about designing and building loudspeakers for my own use, for my own home. I have tried to push the state of the art, because I was never quite satisfied with commercial products, or could not afford what I liked at the time. I also discovered that even the best professional loudspeaker designers had unanswered questions and that I was not alone in that.哈哈，同感，因為不滿意或是買不起只好自己搞囉～
他這隻喇叭的設計非常有意思...
