Make the uppr chamber about 3.7 liters with a vent into the lower around 50% SD. Dont know about the lower chamber volume. I believe it can be established for the same driver parameters except base Vas about 4x the 206e.It works in my pressure/waveform sims but shows a 3 db dip around 120 hz with a lower chamber volume of 60 liters.
Note! this is new and an unexplored terroritory for this action.
