Add the cabin gain into that, and its no wonder you aren't happy with the frequency response. You should build a box to bring your peak down to around 2 db boost, possibly tune it a bit lower, and then make sure you have plenty of port area. You should have 12-16 inches for every cubic foot of internal airspace in the box. then I can guarantee you will be much happier with the SQ of the sub. I'm not sure what size of box you are running, but I would try modeling up a box that is about 3 cubes tuned to 26 hertz, with my WINISD driver parameters, I am seeing an almost flat response with about 2 db's of boost from 26-40 hertz.. The cabin gain will boost it a bit more as well.</p></blockquote><p></p>
