Eminence was founded during the days when American Muscle ruled the road. There was no replacement for displacement, and for those of us in the professional audio industry, that statement still holds true. Professional Audio is experiencing staggering growth. In anticipation of that growth, Eminence charged our engineering team to design the best professional audio loudspeakers in the world. We insisted that they beat the performance and durability of every competitor. The Eminence family of TOUR GRADE loudspeakers, designed and assembled in the USA, represents Maximum Power Handling, Maximum Displacement, Maximum SPL, and unequaled reliability. Advanced measurement systems and FEA optimization tools were implemented on this next generation of subwoofers. *Warranty policy may vary outside of the continental United States and Canada.
