It would probably be right around the same area since the tuning is by default the same. Starting at 40Hz the PB13 would start to gain its advantage over the SB13. It would just grow at a faster rate. I think the PB13 would just be 1.5-3dB higher than the plus at most all frequencies but I'm sure there are others with better measurements.
