Port problems..


Recommended Posts

2 aq hdc3 12's, on 1 aq2200d, Im buiding a box for my ext cab, the box i have now is like 6 cubes and hits 138 at 33 hz, way to low and not loud at all really.. so im looking to atleast hit 142-145 so im building an L port box, around 4.5 cubes before port and sub disp, so 4 cubes after- ish.

Just wondering how wide to make the port from where the subs are, and how many inches above the bottom of the box to make it, along with how wide the exit should be (?" wide by 15 tall)

thanks

I would get a good box design from like ramdesigns on here. Enclosure makes all the diff in the world a properly designed and built enclosure will make a huge diff.

And u might want to try more like 4.5-5.5 cuft for the pair and like 16sq.in. Of port per cu.ft. If i knew how to design boxes i would do it for ya. I can give you my measurements of my 2 boxes one is 32hz tuning and the other is 38hz
