How the level was stated. Printed as Peak SPL at 1 m (active mode); noise type and crest factor not stated.

Coverage definition. Default HF dispersion 60x60 (same in both modes). Optional flanges: 90x40 flange, or 50~90x40 with PS flange. Page does not label axes or define the -dB level; for the non-square options the horizontal/vertical assignment is not stated.

Notes. Pole socket: touring version handles hold a 35 mm pole stand adapter (install version has no handles). Switchable passive/active on Touring and TIS versions; install version passive only. Active recommended power printed as 800 to 1350 W LF + 400 to 630 W HF (two amplifier channels); not recorded as a single power figure.

Coverage shape

Horizontal: 60° (seen from above)

Vertical: 60° (seen from the side)

What the figures mean at distance

Taking 141 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	135.0 dB	2.3 m	2.3 m
5 m	127.0 dB	5.8 m	5.8 m
10 m	121.0 dB	11.5 m	11.5 m
15 m	117.5 dB	17.3 m	17.3 m
20 m	115.0 dB	23.1 m	23.1 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.
