DD was never my favorite sub. the 8 they produced 15 years back was my favorite sub from them, but even when everyone had a boner for DD, I still liked my diamond audio D6 so so much better than any of the DD systems I built. Not sure how either of these companies stack up today, but the diamond audio d6 10 was my favorite sounding ported sub I’ve ever owned. it was clean, loud and still pounds in my brother in-laws car 15 years later. I tried to have a boner for DD back when they were cool, and they are decent subs for the every day hip hop listener, but I just never heard the hype with my own ears.
