"Mr. Overpeck...am I correct in saying the the IDMax, W7, RE XXX, Blueprint 1503, and Brahma have surpassed the EVO in terms of linear excursion??? It seems to me that you whole company is based on Xmax...but there are about 10 drivers that surpass the EVO...would you care to enlighten me???"

Yes, that assessment would be accurate. However, it appears that your not to up to date on published test reports, so I will be happy to fill you in. The EVO 2200 series is our "entry-level" sub. At 14 mm of X-max, it is never was the "X-MAX leader" (though it does have more then any Kicker 10/12 so that is not too shabby.). The comment about the EVO 10 being "the best" was referenced to the 10's that M-E has reviewed in the past several years, and nothing more.
While the other drivers you have mentioned are all excellent, as they all cost far more and feature 3" VC motors, they are more comparable to our EVO-R series, which has more documented X-MAX (how far it can travel before it will begin to distort) then any of the above mentioned drivers, and has moe cone area as well, so that would make it the highest displacement driver on the market....and at $349 (Introductory priced at $314 for the moment), nothing will move more air for similar money...
W7 13 has less cone area and similar Xmax (28 mm).
IDMAX is not available in a 15 and has less Xmax (24 mm)
Blueprint and Brahma has less cone area and less Xmax (25 mm / 27mm)
And there is do documentation to support what the actual Xmax of any of these brands that do offer a 10" can actually do.
But I can guarantee you that our MASS 10 will deliver comparable excurion to any 10 on the market, and do it for under $300...(with less moving mass, lower Fs, lower inductance, more cone area and less distortion).
Xmax is not the be all end all specification in subwoofers, but it will tell you how far the driver can travel (in one direction) before the VC starts to loose so much of it's magnetic force, so that distortion will rise to an audible level. So that makes it pretty important. Because when the VC does exit the gap (given that you have the required power to achieve this), then I can assure your SQ will go out the door...
Hope that proves illuminating...
By the way, comparing any 10" sub (MASS or any other) to any 12" sub (with comparable Xmax) does not prove anything, though we have had a few people do this (hint) and think that this is somehow a valid comparision. Just like comparing an EVO-R 15 to any 12"....it is just not comparing "apples to apples".
Stay tuned for the next issue of M-E...and that should prove to be illuminating (and educational) as well...
