All of the DD subs now come with the new taller surrounds. Just a design improvement DD does on a regular basis.my friend got 2 DD 2512's ordered then , about a month later, he ordered 4 more.. and the last 4 came with Taller surrounds than the 1st two.. Coils read the same and they perform the same..
