What the figures mean at distance

Taking 129 dB at 1 m on axis and the free-field rule of 6 dB lost per doubling of distance, this is the most the speaker can reach and how wide and high its nominal coverage is at each distance. A real room adds reflections, and a speaker is not normally run at its maximum.
