THE SOUND OF INNOVATION Parent company of six major manufacturing brands, MSE Audio utilizes the latest audio technology to produce the best sounding speakers in the world. With multiple design and manufacturing centers across the residential and commercial spheres, our products rely on synergistic, cross-platform engineering to deliver exceptional durability, industry-leading quality control, and refined aesthetics. MSE Audio’s Jacksonville, FL location (home of Phase Technology) occupies a special niche in today’s audio industry as it is one of the few fully vertically-integrated speaker manufacturers in America producing drivers, crossovers, cabinets and systems. Unlike most brands, which rely on offshore manufacturers to design their speakers, every speaker and speaker system in the MSE Audio catalog is designed, prototyped, and performance proven in Jacksonville before being produced in one of its factories.
