MB Quart Discus 6.5" Coaxial Speaker System

MB Quart is a historic brand in the high-fidelity audio industry, originally established in Germany. Known for its engineering excellence in the 1960s and 70s under the company MB Quart Akustik, it became a pioneer in car audio and laboratory-standard headphones.

In the modern era, the brand has transitioned from its German manufacturing roots to become part of the American car audio landscape. Today, the brand is owned by Maxxsonics USA, based in Libertyville, Illinois. While the engineering and design concepts often retain the legacy of the original brand, the physical manufacturing of current product lines, including the Discus and Powersports series, is primarily carried out in China to balance performance with cost-effectiveness for the mass market.
