With the 12BR70 datasheet I have (same as your link) a 130 L sealed enclosure would give you a system Q of 0.72 (little bit underdamped) and Fb of 45 Hz.
But be aware there have been other 12BR70's in the past with slightly different T/S parameters.
In general this woofer is very suitable for a sealed enclosure.
