Eminence NSW6021-6

The Eminence NSW6021-6 is a 21" bass speaker with a 6" copper voice coil and a neodymium magnet system. Advanced measurement systems and FEA optimization tools have been implemented in this next generation of Eminence touring-grade subwoofers. The result is an enormous, unrivalled displacement and exceptional power handling with maximum performance in small to large bass reflex enclosures.
