Overview
These are the legendary Dahlquist DQ-10 speakers, a landmark achievement in high-end audio design that revolutionized how we listen to recorded music. Instantly recognizable by their open-back, multi-driver configuration and striking resemblance to the famous Quad electrostatic panels, they were designed to eliminate cabinet resonance and time-delay distortion.
Story
Introduced at the 1973 Chicago Consumer Electronics Show, these speakers shocked the audio world by proving that dynamic drivers could sound as open and seamless as exotic electrostatic panels. Co-designed by Jon Dahlquist and legendary audio pioneer Saul Marantz, they became an instant cult classic.
Maker / Origin
Dahlquist was founded by Jon Dahlquist, a brilliant engineer who partnered with Saul Marantz—the legendary founder of Marantz electronics—after Marantz had sold his original company. Together in Freeport, New York, they sought to push the boundaries of acoustic engineering, with the DQ-10 serving as their triumphant flagship product that defined the company's legacy.
Condition & Value
The photos show a fair amount of accumulated dust, some minor scuffs on the wooden side panels, and typical wear on the black grille cloth. Crucially, the foam surrounds on the internal woofers are highly prone to rotting over time and likely need to be re-foamed if they haven't been serviced recently.
