this is the model i have in my car now. It's a very nice competition level sub.  It's as good as anyone's with only 1/3 of its power handling used. i built a box myself its ported and tuned to 26 Hz

I've seen a few b4 on ebay for cheap. the design sees very similar to some legacy subs that i've seen b4.
