The design goals of these drivers were to create around 3 db of ripple and a f3 of 28 hertz in a recommended ported enclosure of 3 cubic feet for the 15 and 1.5 cubic feet for the 12 tuned to 32 hertz.  Below is a screen print of the 12 and 15 in their respective enclosures.

edited for you.  This is why it's not locked.  I have a bad habit of forgetting the details.

When you get a chance will you put the table with the different enclosure's and there respective info.

You get the final parameters for the bandpass 12 also?

Hell yeah!
