Yup thats the wall, only mods were:

45's on all corners of the box

Much bigger port area

Those 2 simple change made the world of difference!! I went from 147.xxDB @ 38hz to 149.9DB @ 32hz, my 25hz score has gone up a whopping 5 DB!!! And those scores are with the wall unselaed, will try to seal it this week and re test, as I also got my O scope so I can turn the amps up a bit more now
