i've done a couple of boxes for dd1508's. one was .6 cubes ported at 36hz, the other was 1 cube ported at 34hz. sounded good even in the undersized box. i have never built a box for the 8w7, but i've heard 2 different setups. one being the HO box from JL, and the other box i never got to find out the specs. although i liked the sound from the JL better, the DD was noticeably louder. it wasn't ridiculously louder, but my ears gave spl to dd and sq to JL.
