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.

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.
