YellowB Posted April 27, 2018 Report Share Posted April 27, 2018 Hey guys looking some serious help on a box's for 2 soundqubed hdc310 I build 2 box the first one dimensions is H-11"xW-48"xD-17" port is H9.5"xW-4"xL-43 said to be tuned around 27 Hz had a nice drive but was tune to low so I build. Next one dimensions was H-11"xW-50"xD-17" port is H-9.5"xW-5"xL-30.5" said to be tune at 33Hz this one had a cleaner an deeper drive to me which I like but I had to increase the the gains, both box had double baffle. Am trying to get the most sql out of them. Dimensions area I have is H-11"xW-55"xD-18". Link to comment Share on other sites More sharing options...
ckeeler11 Posted April 27, 2018 Report Share Posted April 27, 2018 The box is a little on the small size. Ideally you would be closer to 3.25 cu ft. net. right now you are at 2.5 cu. ft. tuning is going to be around 36 on your current box as well. Increasing box size will give you more output. Should be no need to change gain setting unless you switched headunit. The gain is not a volume knob. Link to comment Share on other sites More sharing options...
YellowB Posted April 27, 2018 Author Report Share Posted April 27, 2018 OK so u would recommend I go the full dimensions of H-11 I can't go no higher W-55 can't go no wider D-17" I could go 18" may be 19" the most.

ckeeler11 Posted April 27, 2018 Report Share Posted April 27, 2018 If you can go to 19"d then that would put you at 3.25 before sub and bracing displacement which is closer. Link to comment Share on other sites More sharing options...
