How the level was stated. 1 m, free field, peak SPL, pink noise crest factor 4, one speaker driven; may deviate with several loudspeakers. Figure depends on amplifier.
Notes. Page states omnidirectional dispersion. M20 threaded flange on top for the d&b stand winder (no pole-mount rating printed). Dimensions printed H x W x D 426 x 530 x 550.
What the figures mean at distance
Taking 130 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 | 124.0 dB |
| 5 m | 116.0 dB |
| 10 m | 110.0 dB |
| 15 m | 106.5 dB |
| 20 m | 104.0 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.
