OPTIMIZING SETTINGS/TROUBLESHOOTING
Optimizing settings/Troubleshooting General tips
Check it out Try different subwoofer positions and settings, before you finally choose a setup.
Note down settings When looking for the best subwoofer position in the room, note down the ideal setting you
found for a position. When moving the subwoofer between two positions you will be able
to set the subwoofer to the same configuration as found before.
Vary the listening music When experimenting to find the optimal settings, use a couple of music tracks with
repetitive bass across a large spectrum. The tracks should be sufficiently different from
each other and each should cover a wide bass-range. Musical instruments, such as a
double-bass, bass guitar, church organ, etc. covering a wide spectrum in the bass region
and above, are very suitable as these depend on accurately balanced subwoofers and
main speakers.
Verify changes Although in general it is best to make adjustments in the sequence outlined below, note
that changing one setting may influence another. For example, finding the right setting for
phase may result in having to decrease gain, even if this was set correctly before. It is
recommended that you double-check the previous settings before moving on to the next
one. Obtaining the best integration of the subwoofers generally involves a considerable
amount of repeated fine-tuning.
Volume (GAIN)
With the GAIN control you can adjust the relative volume level of the subwoofer to the
main speakers of the system:
Play the same track a couple of times, adjusting the level so that the instrument sounds
homogenous across its range.
If you find that at certain specific bass tones the response is either too loud (bloated
sound) or soft (thin sound), it may be that you have to experiment further with the location
of the subwoofer and/or the cross-over settings.
