Genelec 6010A Setup Manual page 12

The monitor radiates omnidirectionally at low
Sound radiation
frequencies. At higher frequencies, the energy
radiated becomes increasingly directional: midrange
frequencies radiate in a hemispherical pattern and
high frequencies in a beam- or ray-like pattern. All
this sound energy refl ects from the walls around and
should be controlled.
SPL
low frequencies
Ideally, free standing monitor has a fl at frequency
Radiation load
response. Placing the monitor near the wall boosts
the low frequencies; one wall up to +6 dB, a two-wall
corner (or wall and desk) up to +12 dB and a two-
wall corner with fl oor, desk (or even ceiling) boosts
up to +18 dB. Genelec speakers come with DIP
switches which are designed to compensate this
boundary load effect. (AutoCal in DSP systems.)
