As an American expert brand of custom cinema, American OSD Audio is different from traditional speaker brands. For decades, it has been focusing on the design, development and manufacturing of custom-installed cinema products. From the excellent sound quality performance of the speakers to the product design bias, product detail design, and installation convenience in custom theaters, decades of custom installation experience have been devoted.
