The Dahlquist DQ10 was the first loudspeaker manufactured by the Dahlquist company, then based in Hauppauge New York. Among the company’s founders were some famous names in audio, such as Jon Dahlquist and Saul Marantz, Irving M. Fried and Werner Eymann. The DQ10's design was first exhibited at a New York audio show in 1972. It was revolutionary, because it parted with the traditional boxy shape of conventional speakers. Dahlquist had instead constructed a cabinet that suspended its drivers freely in an open array and in correct phase alignment. From the DQ10 onwards, the term 'Phased Array' became the Dahlquist trademark.
