Its not so much that your box is tuned differently.The only thing I don't get it why my sa played everything well, and that box was 34hz. So either 32hz is really THAT different, or sa's are better than z's in that area somehow.
The way your subs specs and box dimensions come together, the bandwidth is small and peaky.
Your SA probably had a larger bandwidth and a flatter response curve.
