I'm looking to build a box for my 12'' AQ sdc2.5. Wondering how many cubes to put it in and to what tuning. I was thinking around 3cubes and tuned to 38hz. Sound good?

So more around 2.5, how much port area would you recommend?

edit: Does anyone know about how much the woofer displacement is?

Sub disp. is .1^ft port area i would do between 25 to 40 sq. inches

2 cubes 38Hz with 32^2 of port area will work well...
