    I tried to get a flat responce with the dsp and highpass a bit below tuning point and even a bit higher then tuning point to get rid of over excursion but it didn't work and i still was missing around 4 db. But i think the last graph showed exactly what is happening now. I gonna use the nd105 PR to get max spl.

      Hi guys, i found out that only the bass at tuning frequency is lacking. I took out the passives and sealed the enclosure to make it a sealed enclosure and put a 50 hz test tone tru it. It get me around 76db wich is close to the simulated output ( 80db at 50hz with 4mm xmax ). The weird thing is that with the original enclosure with 2 nd105 passives, i only get around 78 db with the same power, while tuning point is at 54 hz. The passives are moving enough, how is this possible? I schould AT LEAST get 10db more! I really don't know what i'm doing wrong. I measured multiple speakers at the same spot and get the spl it supposed to have, even with the sealed design..
