Tour Grade Subwoofer with 6 Ohm
21-inch Tour Grade – American Muscle Arguably the best 21-inch subwoofer on the market. Advanced measurement systems and FEA optimization tools were implemented on this next generation of tour grade worthy subwoofers by Eminence. The result is absurd, unrivaled displacement and exceptionally high power handling with top of the line performance in small to large vented enclosures.
