reinke Posted September 14, 2008 Report Share Posted September 14, 2008 my box is 32x28x21 tuned to 32 hertz. i want to raise the tuning to around 38 or so. how the hell do i do it. i love the lows but i am lacking horribly on the top end. i didnt realize alot of the songs i listen to daily were that high Quote ----reference's---- meade916 Link to comment Share on other sites More sharing options...
95_1500 Posted September 14, 2008 Report Share Posted September 14, 2008 I believe i am correct when i say shorten the port. Do some calculations with shorter port lengths in relation to how much it alters the inner volume until you get the tuning youre looking for.

David Posted September 14, 2008 Report Share Posted September 14, 2008 what kinda port? if its a areo port just cut off an inch and try it out, keep doing that untill you get what you like. if its a wood slot port, if you can pull the port out do the same take off an inch and test it out, if the slot port isnt removable your gonna have to build a new box Quote Link to comment Share on other sites More sharing options...

duct_tape123 Posted September 15, 2008 Report Share Posted September 15, 2008 (edited) If you can afford to(if you have enough ft^3), screw some 2x4's in there. As the volume decreases the tuning goes up. Edited September 15, 2008 by duct_tape123 Quote Link to comment Share on other sites More sharing options...
Torres Posted September 15, 2008 Report Share Posted September 15, 2008 what are the dimensions of your port? i can help you get the right length so you only have to cut once. and those dimensions i'm going to assume are outside dimensions?

Clif Posted September 16, 2008 Report Share Posted September 16, 2008 are you using the plans i gave you? or diffrent ones? and yes you can either cut the port length down, or either add some internal volume to it by means of 2x or somethen else.
