The Tour Grade line-up represents Eminence's top-of-the-line subwoofers.  The NSW6021-124 is the highest excursion 21" that we carry (and it may be the highest excursion 21" pro-audio driver period).  It is capable of extreme amounts of low end output, even exceeding the venerable LaVoce SAN214.50 by approximately 2dB.   

The NSW6021-124 works well in all our 21" cabs from the MBM-21 to the Devastator. 

In order to realize its full potential, we recommend a high power amplifier, such as the SpeakerPower SP1-4000-HT/SP1-6000-HT plate amps or the SP2-8000-HT/SP2-12000-HT rack amps.
