Answer 1

I answered this one the last time you asked it. Email me if you want a box designed for those subs.

Answer 2

true...you can't just buy any ported box and expect it to work well with any sub you throw in it.  

Answer 3

yeah, ur prolly gonna need a box built to the speakers specifications....

Answer 4

Simple that box just doesn't work for those subs. If you want the best sound for those subs, or any subs for that matter. Build the box according top the manufactures specs on the subs.
