How the level was stated. Printed as 134/133 dB peak; footnote: measured at 1 m using broadband pink noise at maximum output.
Notes. -3 dB response 45-150 Hz. Page mentions Cardioid Control Technology (up to 35 dB reduction on stage when multiple subs are deployed) but that is a multi-sub array/DSP feature, not a stated single-unit pattern, so pattern left omni/not stated; owner to decide. Height printed as "455 in" (typo); recorded as 455 mm, check datasheet. M20 pole mount plate. No sensitivity printed. Page was the Spanish-locale URL but contained English-format spec values.
What the figures mean at distance
Taking 133 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 | 127.0 dB |
| 5 m | 119.0 dB |
| 10 m | 113.0 dB |
| 15 m | 109.5 dB |
| 20 m | 107.0 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.
