I used Dayton Audio RSS315-PR radiator. I optimised the box to not fall in "-" at higher Hzs after that peak on ampl. resp. and SPL graphs. Power handling on RMS power is ideal down to 19-20 Hz. I dont know that this box is OK, or not (so please rate this project), because I have no experience with passive radiators (I've tried to design first time ever with it), and group delay: everywhere is under the dashed line, so it is OK, just I do not understand the negative numbers in it...

I simulated all types of boxes. The Vbs are the largest and Fbs are lowest possibe: to have the lowest possible F3, to have acceptable group delay everywhere, to reach 0dB in amp. resp., at 10 / 20 Hz and above to have ideal power handling - reach but no overpass the Xmax + acceptable vent air velocity. All are buildable, but I prefer the 4th order bandpass box for this woofer (it is on 3D), because of it's power handling, compactness, and performs very similar at low bass like the 6th order box.
