Primarily for 18" B460 equivalent, but there's info (pg 6) on B380 as well:

I built a pair of the B380 clones back when that article came out. I used new 2235's and had to recone them a couple of years ago due to deteriorated surrounds. I still have them and they are still a remakable pair of subs.

Highly recommended.
