has a new baby and I am now in construction season and working 80-90hrs a week, so not much modeling is happening currently.
I’m home for the weekend though, so will try to help out a bit.
I’m not sure what driver or amp you’re using, so I modeled with a saf184.03 on 1000w.
Open has a 17hz tune, 17hz 3rd order HPF.
1 plugged has a 14hz tune, 14hz 3rd order HPF.
2 plugged has a 10hz tune, 10hz 4th order HPF.
Excursion is approaching 20mm on both plugged configs, more than this driver will provide. So you won’t be getting the full output modeled at low frequencies. I wouldn’t worry about driver damage from over-excursion with these drivers though.
We are well below the intended frequency range of this driver, so port velocity isn’t too out of control with one plugged, 26m/s.
I wouldn’t suggest running two plugged, velocity is approaching 40m/s.
Honestly, I would run all open, but one plugged should be usable as well.
Not sure what other advice you’re looking for.
