Passive radiators have their place, and its not in a subwoofer enclosure.
the purpose of these is to add bass to a full range box without changing the impedance of the enclosure, and having to add extra drivers.
They will produce low frequecies but are powered by the mid/low rannge driver in a sealed enclosure. So if the mid driver is notvery good, and has a small displacement the dont expect alot from the passive radiator.
Years ago I had a high end set of Kicker sidekicks that used 8" passive radiators with 6.5" mid drivers. They sounded awesome, but they werent subs.
If you want the low sub bass pnch, and you cant afford a set of 15" L7's then get a 12" kicker comp.
What kind fo music do you want to listen to with this system?
What sort of bass are you wanting to produce?
Different types of enclosures produce different tones and resonances.
I had a 12" Comp in a folded horn sub box that was unbelievable.
