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.
