Adjustment
In order to adjust the RHEA II to your main speakers and listening room, we recommend that you take
the following steps:
Switch on the RHEA II and play some well-recorded music with broad bass content through your
system.
Adjust the volume level until ideal blending of the deep bass range with the rest of the music is
obtained. At this early point of adjustment, occasional booming at single frequencies or some dryness
or softness of the bass is insignificant.
Once the volume level of the deep bass range has been set to the position which achieves truly
seamless blending with the rest of the music, you need to select the right polarity. Use the phase
function to set the polarity to 180° and compare the sonic results with the previous setting. Change the
polarity repeatedly between 0° and 180° and compare the sonic results of both settings. You will
realise that one of the two phase settings excels with an extremely balanced and homogeneous bass
reproduction in the mid-bass region. This is the optimal phase setting for obtaining maximum listening
pleasure.
In some cases, however, a change of polarity may lead to an increase or decrease in the bass level. If
this is the case, we suggest that you rotate the multifunction switch to adjust the volume accordingly.
The next step consists of setting the right crossover frequency. While you are experimenting with the
ideal setting, pay close attention to unnatural irruptions (the instrument is weak and appears to play
single tones too shortly) or peaks (the instrument starts to thicken up single tones and extends them in
an uncontrolled and unnatural way). Correct adjustment of the crossover frequency allows for an
imperceptible bass transition between the RHEA II and the main loudspeakers.
After the right crossover frequency is set, your RHEA II is perfectly adjusted to the main loudspeakers.
When you have completed this adjustment step, we recommend that you fine-tune the volume once
again.
Now you have successfully completed the adjustment of your RHEA II subwoofer.
You have opened the door into a new dimension of music reproduction and superb bass performance.
Music material we recommend for adjustment of the RHEA II is also provided on the Audio Physic
Reference CD.
