Frank ... Glad you are liking the graphs... They show the B4+ has very food dynamics, lots of power, and extension.
I wish (as in Craig, you bonehead) that I had managed to SAVE the graph which showed the 118 dB at 20 Hz... instead of accidently deleting it, and NOT realizing it until AFTER the beast was in the house and running there...
It (the 118 dB graph) showed a less compressed 20 Hz signal, and lower distortion levels... The SPL at 40 Hz (first distortion frequency) was at 95 dB ... then, with 2 dB more 20 Hz output, the 40 Hz jumped to what you see here...
The B4+ will "only" hit 118 dB at 20 Hz/one meter before (outside groundplane measurements) severe clipping or compression sets in.
