Tuning for a powerbass 3xl 12" sub?

[AARON30]

Just got one today and cant find what im supposed to tune it @...please help
would love to make a 4th order bandpass for it, but i am totally lost on building one to sound good...
SO JUST A SIMPLE SLOT PORT BOX WILL BE FINE, JUST NEED THE INFO...THANKS

They are made for ported boxes. I suggest tuning it to 33hz, because they hit lows like a mofo with that nice excursion.

Then how big of a box do they need? 2.5cu.ft-3?
The box i just played it in was tuned to 33 but was a round port and box was 2cu.ft....thanks
