Table 1: Suggested tone control settings for various acoustical environments

gives the desired playback level and good resolu-

tion of the volume control.

Setting the tone controls

The frequency response of the Genelec 4010A can 

be adjusted to match the acoustic environment by 

setting the tone control switches on the rear panel. 

The controls are “Treble Tilt” and “Bass Tilt”. An 

acoustic measuring system such as WinMLS or 

comparable is recommended for analyzing the ef-

fects of the adjustments, however, careful listening 

with suitable test recordings can also lead to good 

results if a test system is not available. Table 1 

shows some examples of typical settings in various 

situations. Figure 4 shows the effect of the controls 

on the anechoic response.

Treble Tilt 

The Treble Tilt control (switch 3) attenuates the treble 

response of the loudspeaker at frequencies above 5 

kHz by 2 dB, which can be used for smoothening 

down an excessively bright sounding system.

Bass Tilt

The Bass Tilt control offers three attenuation levels 

for the bass response of the loudspeaker below  

2 kHz, usually necessary when the loudspeakers 

are placed near a wall or other room boundaries. 

The attenuation levels are -2 dB (switch 4 “ON”), -4 

dB (switch 5 “ON”) and -6 dB (both switches “ON”).

Mounting considerations

Align the loudspeakers correctly

Always place the loudspeakers so that their acous-

tic axes (see figure 1) are aimed towards the center 

of the listening area. Only vertical placement is pre-

ferred, as it minimises acoustical cancellation prob-

lems around the crossover frequency.

Minimise reflections

Acoustic reflections from objects close to the 

loudspeakers like walls, cabinets etc. can cause 

unwanted colouration of the sound image. These 

can be minimised by placing the loudspeaker clear 

of reflective surfaces.    

Minimum clearances

Sufficient clearance for cooling of the amplifier and 

functioning of the reflex port must be ensured if 

the loudspeaker is installed in a restricted space 

such as a cabinet or integrated into a wall struc-

ture. The surroundings of the loudspeaker must 

always be open to the listening room with a mini-

mum clearance of 3 centimeters (1

above and on both sides of the loudspeaker. The 

space adjacent to the amplifier must either be ven-
