Listening distances and sound pressure levels
The short-term and long-term sound pressure levels (SPL)
listed take into consideration typical room environments parameters
for each product (ITU-R BS.1116-1 Recommendation):
a) variable typical room volumes
b) variable typical room reverberation times (RT60)
If the room reverberation time is longer, it will mainly affect
the long-term sound pressure levels that will be higher than
the ones shown.
Not recommended distances
When the distance to the monitor is too short, summing of sound from
multiple drivers is not happening as designed, and this affects the
flatness of the frequency response. A flatter and more stable frequency
response is obtained at a larger distance.

Short-term sound pressure levels
Maximum short-term sine wave sound pressure level
averaged from 100 Hz to 3 kHz, measured in half-space,
on-axis (no weighting).
Long-term sound pressure levels
Maximum long-term RMS sound pressure level, measured in
half-space, on-axis, with simulated programme signal according to
IEC 60268-5 (limited by driver unit protection circuit, no weighting).
