I can also recomend a few tips, and "Do's and Dont's" about box building if you would like. I will be back on later on tonite. Buzz me if youre interested. |

Silver Member Username: NysteelersPost Number: 106 Registered: Aug-04 | thanx man. this is for both subs right, cuz thats a pretty large box. and would it be common chambered then? |
|
Silver Member Username: MixneffectOrangevale, Ca. USA Post Number: 230 Registered: Apr-05 | No, that is for each box. Note; these alignments give you a much lower cutoff than what the manufacturer recomends. Thats why its a bigger box. I am guessing that the program is taking into accout the Vas and therefore has suggested a box that is compliant with the same pressure as the Vas compliance. |
