Overview

Eminence NSW6021-6 21" Professional Neodymium Tour Grade Subwoofer Driver

If you need more bass, a lot more, then Eminence's NSW6021-6 is the driver for you. This massive 21" professional subwoofer is the ultimate of combination of efficiency and displacement making it one of the highest output subwoofer driver ever made. With an Xmax of 21 mm and sensitivity of 97 dB, this subwoofer is something special. Using a 6" voice coil with extensive venting, the NSW6021-6 can safely handle up to 2,500 watts RMS (5,000 watts peak) for the most extreme situations, while keeping power compression to a minimum. To keep weight reasonable the motor uses a huge neodymium magnet to drive the voice coil. The revolutionary wet pressed X5 pulp cone and dust cap provides the superior strength and rigidity required to support the excessive amount of force the motor and voice coil can produce. If you need unmatched output, low frequency capability, and long term durability, then the Eminence NSW6021-6 is the driver you have been looking for.

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 thier 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.
