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.

Distance	Level on axis	Coverage width	Coverage height
2 m	123.0 dB	4.8 m	4.8 m
5 m	115.0 dB	11.9 m	11.9 m
10 m	109.0 dB	23.8 m	23.8 m
15 m	105.5 dB	35.8 m	35.8 m
20 m	103.0 dB	47.7 m	47.7 m

See level and distance and coverage angles for how these are worked out.

Planning estimate only. The calculation ignores reverberation, reflections and room modes. See terms and disclaimer.
