EQ

This control allows you to adjust characteristics of the subwoofer to match the  room 

and speakers in your system. EQ “equalization” aims to get as even frequency 

response as possible in your sound system.

SUB EQ 

The subwoofer has a switch marked with “EQ”, this allows you to choose between 

three different EQ “Characteristics” settings.

-REF gives a extended frequency response for the deepest bass, however the 

lower frequencies can be over represented and “muddy”, depending of the room 

geometrics, placement of the sub and listening position. (Reverberation)

-EQ1 is a direct countermeasure to the “muddy” bass problem of over 

represented low bass/room gain, by lowering the bass extension, the bass will be 

more controlled. 

-EQ2 stores more energy a bit higher in the frequency, recognized as a more

punchy fast bass

The picture below shows the effects of the different EQ settings.  

(These curves illustrates the frequency response of a anechoic  room, have in mind 

that the frequency response will change depending of the room and placement of 

the subwoofer and listing position. E.g. A setup in a regular room with the EQ 2 

could have a total frequency response that extends much lower than represented 

in the graph below due to room gain.
