How the level was stated. Printed as Peak SPL at 1 m; footnote says install version may be slightly degraded by front cloth. Noise type and crest factor not stated.
Notes. No directivity pattern is printed (cardioid appears only in brochure system examples). M20 thread on top for pole stand. Dimensions printed H x W x D 559 x 680 x 775. No sensitivity printed.
What the figures mean at distance
Taking 140 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 | 134.0 dB |
| 5 m | 126.0 dB |
| 10 m | 120.0 dB |
| 15 m | 116.5 dB |
| 20 m | 114.0 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.
