Skrilla Posted December 31, 2010 Report Share Posted December 31, 2010 Sounds like it's tuned pretty high. I'd say close to 50Hz. Quote 2 HDC3 18's AQ2200D Link to comment Share on other sites More sharing options...
fecupe2001 Posted December 31, 2010 Report Share Posted December 31, 2010 If that box has 3/4" wood thickness, then it´s around 46 hz without including the sub displacement, so yes, it´s between 46 and 48 hz depending on the displacements you have inside the box.

fecupe2001 Posted January 1, 2011 Report Share Posted January 1, 2011 For daily i would tune around 35 hz, also, the FS of that sub is 35 hz if i remember correctly so i wouldn´t tune below that, port tuning changes when you add or reduce the port lenght, but also, when you get bigger or shrink the internal space of the box. Said that, modding your current box would save you some money!! Quote I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.

fecupe2001 Posted January 1, 2011 Report Share Posted January 1, 2011 Remember that adding lenght to the port would also shrink the internal space of the box, what sub or subs are you using on that box? would need around 20" long to get a 35 hz tuning!
