In the new Mobile Entertainment book it says the New Sub-zero have 4" plus xmax. And its rate at 600 rms 1200 peak. How does the IDMAX and XXX compare in xmax.

4" Xmax means the subwoofer has 8" of linear travel. Since it's in Mobile Entertainment it's not a dipole theater subwoofer (ala Parthanon). This figure is impossible using any conventional spider/surround assembly and would require an enormous motor. I'm guessing that the information within the magazine is flawed due to editors on crack.
I just looked it up on the CES Website. Capable of 3.5" peak to peak travel. Which means its Xmax hovers nicely around 1.25" or thereabouts. So, in closing, I uphold my crack comment previous.
Earthquake Sub Zero 12 inch subwoofer. ($515) "The sub zero houses a "triangular lattice" flaat piston, said to prevent cone distortaion. Its rated to take 600 watts rms, 1200 watts peak, and over 4-inches long-throw excursion." I thought xmax and excursion where the same thing. Whats the difference?
Xmax is one-way linear excursion. The 4" excursion number is a peak to peak figure, based on the maximum distance the sub goes from one direction to the other. Companies tend to use peak-to-peak numbers instead of Xmax because it sounds more powerful, but I think it's fairly shady.
