Whats the current build time for the X 12?

Also, are they better sealed or ported? Looking for a good SQ setup that can get somewhat loud. How does the X compare to other subs in its class, like the DCON?

I have a Fi X 10" in the recommended ported box 1.14ft^3 tuned to 32 and it got plently loud in my explorer off 160 watts. Im gonna put in my civic in a sealed box off the same power and am looking for good results. They will work good in either sealed or ported. I love the way this subs sounds so i wont be getting rid of it nor am i sad i didnt buy another brand.
