It's all about the box every sub has it's own sound and honestly alot of subs believe it or not sound like crap I'd have to say dds usually do well and sound great on the highs and lows. My tsns makes me miss the highs but it is doing better #s than my dds did I'm doing a 147.5 on a 2011 tsns 18 at 37 hertz my dds and aqs liked about 45 hertz and the max I got was 146.4 off two aq 15s this is all out of a impala trunk on musical setups. One of the cleanest subs I had was a pioneer ts w8102spl. I wanna try the hdc4s though that twelve looks like a gorrilla.
