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.

Coverage definition. Page prints 80 x 50 as h x v, rotatable to 50 x 80; no -dB definition stated.

Notes. Pole mount: hidden socket for stands. The architectural spec text says max SPL "at least 134 dB". Power 300 W RMS / 1600 W peak (10 ms), 8 ohm. E12-D variant (110x50) is a different product, not recorded.

Coverage shape

Horizontal: 80° (seen from above)

Vertical: 50° (seen from the side)

What the figures mean at distance

Taking 131 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	125.0 dB	3.4 m	1.9 m
5 m	117.0 dB	8.4 m	4.7 m
10 m	111.0 dB	16.8 m	9.3 m
15 m	107.5 dB	25.2 m	14.0 m
20 m	105.0 dB	33.6 m	18.7 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.
