[QUOTE="audioholic, post: 7256103, member: 549629"] You dont tune higher to get higher frequency extension, you tune higher to get enclosure tuning, where the enclosure/subwoofer is most efficient, closer to vehicle resonance, to mate the two together and increase output in that limited bandwidth. A sub tuned to 30 hz, or even less, should have no trouble reaching 80hz or so, where you'll cut it off and the mids will start playing anyway. Maybe Ive forgotten, but I dont recall you telling us if this system is for playing music, or burping tones at comps. If its for competition, map out your vehicle freq resonance and tune accordingly. If its for music, ya, tune in the low 30's (probably, Im not familiar with the HDC). You swaying back and forth from 38hz tuning to 30hz tells me you need to consider what I said above a while longer, before you start cutting wood. [/QUOTE]
