Eminence NSW6021-6

Recommended Posts

You may have heard...You may not. Eminence is upping their game and coming out with pro woofers that compete directly with the competition. I was able to get some early samples of their 21. So far what I've seen from this woofer is very encouraging. Specs, notes and impedance curve from one of the sample units are posted. Much more info will be coming.

It goes back to everything being a compromise. Mms is similar between the 2 which is what matters ultimately and the coil size is nearly the same as well. Copper wire of course weighs more for the same volume of material. The min impedance is 5x higher on this driver so some different choices in the wire gauge and number of turns are required to result in the higher impedance. The inductance on this driver looks good too even with the big coil. This driver doesn't have quite the same normalized motor force but its still over 300. The 2ohm version of the Ipal has a lower motor force too probably due to changes in the coil material and winding length needed.

I like the 1.9mm WW,  its about time pro drivers got more, that was the intent with the Pro 5100 we designed back in 2009, took 10 years before that got more mainstream, but its good its happening. SPL still high, but these drivers won't crap out at 20Hz like Eminence of years past. The 6" should have a nice edge in power handling. I still like radial neo more (personal choice), but these puck magnets with wide coils are serious contenders.  @radulescu_paul_mircea I'm not so sure the neo quality anything to question, its 3 lbs of neo! Not a small amount by most standards.

It seems Eminence went for a different chassis. The old one probably was too similar to those from B&C 

Yes they had to tool a new frame. I have sample drivers with the old frame so I was asked not to post any pics of the back of the driver. Ill be getting a pair with the new frames as well. 

Also GP testing of this driver is done. It's a beast.

Sealed. Also did 4 other pro 21's the same day. Working on getting all of that uploaded to the site. Ill probably run these in the skram enclosure.
