toaster Posted May 7, 2010 Report Share Posted May 7, 2010 I would tune a bit higher, ~37hz.

-Hobby- Posted May 7, 2010 Report Share Posted May 7, 2010 Tune higher like toaster said. No need to tune so low, the HDC3 will still hit deep and low with higher tuning. 36 is the recomended tuning and I would even go as high as 37-38 without hesitation. 16-18 sq in of port per cube net for your port area works good for SPL and still sounds good with music. My box finished out at a little bit over 3.6 cubes net per HDC3 15, if that size above is your net you should be just fine. Link to comment Share on other sites More sharing options...
