20-39 PC-Plus

Where does this sub sit in the SVS line compared to a box? Would it have the same or more output/bass then the PB12-NSD?

The 20-39PC+ has more output than the PB12-NSD over the common bass ranges. It falls a bit shy of the PB12-Plus (the box versions tend to be a bit more efficient overall).

Ilkka's CEA 2010 data is a good comparison between the PB12-NSD and the 20-39PC+ in various tunes.

Note that as the subwoofer is tuned deeper, there is a headroom loss over the mid-bass frequencies in exchange for the improved output at very deep frequencies. The native 20 Hz tune is the strongest over the common bass regions.
