I decided there and then that this guy Jon Dahlquist must know more about speakers than anyone else.вЂќД¬arl was soon deeply involved in Dahlquist full-range speaker design and was ultimately responsible for DQ10 modifications and all the Dahlquist speakers that followed that model, including the DQ8, the DQ12, the DQ20 and DQ20i, and the firmвЂ™s box speakers series. The sound was so live I couldnвЂ™t believe my ears. They were playing a speaker shaped like the Quad 57, but it was a dynamic speaker, and there was a big sign saying, вЂThis Is Not An Electrostatic Loudspeaker.вЂ™ They were playing a tape of a live recording of a marching band through a Tandberg 64X. Carl did the electronics while Saul handled graphics.Д¬arl had attended many of the New York City hi-fi shows, and he recalls a memorable event from the early 1970s: вЂњI walked into a room at the New York Hi-Fi Show and saw Saul Marantz with another, much younger man - I was told his name was Jon Dahlquist. That resulted in a product known as the LP1 variable low pass filter. In 1976, Carl Marchisotto joined Saul and Jon as chief engineer, and his first assignment was to develop an electronic crossover for a Dahlquist subwoofer. In 1972 the Dahlquist speaker corporation was born, although it wasn't until 1973 that they introduced their defining product, the DQ-10. His name was Jon Dahlquist and after hearing the prototype DQ-10's, Marantz sensed his greatness and immediately bought 49% of Dahlquist. The man by trade was an engineer in the aerospace-industry and had played a key role in the development of the lunar landing module. About 3 years after Saul Marantz sold his company to Superscope Inc, he discovered another great talent who was obsessed with designing the perfect speaker.
