Have you inspected the sub when taken outside the box, and tried a few free air sine waves? If it sounds good to you then try switching the subs into different holes to see if the one that sounded good earlier, and vice versa.

I found SSA Originally on youtube, and then one day I saw a truck drive by with a Team SSA decal on the back window. Of course I had to run over and see what was in there, single Zcon on a SAZ4500.1, thats when I Truly found SSA.
