What the figures mean at distance

Taking 134 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	128.0 dB	4.0 m	2.3 m
5 m	120.0 dB	10.0 m	5.8 m
10 m	114.0 dB	20.0 m	11.5 m
15 m	110.5 dB	30.0 m	17.3 m
20 m	108.0 dB	40.0 m	23.1 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.
