Not recommended
When too close to the monitor, the
drivers - tweeter or midrange/tweeter
- are not summing together properly at
the crossover point, which affects the
perceived frequency response balance.
Recommended
The long-term sound pressure levels
(SPL) displayed take into consideration
an average room reverberation time
(RT60) of 0.3 sec.
Note: at extremely long distances the
SPL may become too low for the ap-
plication.
