Can I get some help to figure out this sundown 18" s model and specs ?

[Jacobfrome]

I bought this pair of 18"s 4 years ago used . I have no way to reach the seller to get specifics of them . Here are some things I have to help figure it out . They are testing at 2ohm at each of the 2 coils , they weigh 66.9 lbs , the cone measures 6 " , magnet is 9" wide and 5.5" tall . Would appreciate any help to identify this sub . Thank you in advance!

Thank you in advance!

From those angles it looks like the x-18 v2. Only the color looks different. Take pictures of the back and sides.

Ok here are some more picks , they have been reconed and painted before I bought them which just adds to the mystery

Contact Corey Dean spl audio his recones use blue spiders. Zv4 v1 used less vent holes and the older baskets Before they tooled their own.
