Based in Southern, California, OSD Audio (Optimal Speaker Design) designs, engineers, and distributes exceptional audio products for residential and commercial use. Beginning almost 20 years ago with a line of outdoor speakers,  OSD Audio quickly gained attention for building rugged and realistic-looking rock speakers that sounded better than pricier brands. Since then, we've grown into a one-stop-shop for everything home audio, from simple and affordable in-ceiling/in-wall speakers to robust whole-house audio systems, home theater subwoofers, and amplifiers. OSD Audio places value on styling, sound quality, build quality, and affordability because we believe everyone should be able to enjoy great sound. To gratify the most discerning homeowners and A/V integrators, we launched OSD BLACK, a bold line of speakers, amplifiers, and fit-and-finish accessories that combine the most advanced technologies and components for a sound experience that is richly detailed and emotional. OSD BLACK in-wall, in-ceiling, and stand-alone speakers deliver a musical and cinematic experience comparable to some of the industry’s highest-end models. OSD BLACK products are sold only through custom audio/video integrators experienced with the installation intricacies required to ensure that all BLACK products perform at an optimal level.Whether you purchase OSD Audio or OSD BLACK, we back up every product with top-level customer service and technical support.
