RE Audio Question

Does anybody of the specs for a SX12?  I am also having a hard time figuring out there page.  On the SQL part of this sub it says to run it in a box of 1.9 at 32HZ and then if you go to there eclosesure part it says the box for this sub is 2.5 at 35HZ.  How am I supposed to construct this box I have it with new demensions at 1.9 with out the speaker displacement.  Do do you figure in speaker and port displacement when building the box?

Thanks

I have the box design ready but, the guy does not have the speaker yet it has been ordered and I can not find any specs on this sup and on there site it says the speaker is supposed to have a 1.9 cubic box and when I go to the box part of there site it says the box is going to be 2.5 with there numbers.  I just want to know how to figure in port displacemetn and speaker displacemetn into a box when building it how to get the area of a port and all that.

go to products, subs, se, ts and at the bottom it has the displacement for the sub.

You can use this great calculator to help design your box. It usues slot ports though.
