What the figures mean at distance
Taking 132 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 at each distance. A real room adds reflections, and a speaker is not normally run at its maximum.
| Distance | Level on axis |
|---|---|
| 2 m | 126.0 dB |
| 5 m | 118.0 dB |
| 10 m | 112.0 dB |
| 15 m | 108.5 dB |
| 20 m | 106.0 dB |
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.
