While observing an SPL meter (or listening to the mid-bass level), have an assistant adjust the
-
"PHASE" switch between 0° and 180° and observe any change in mid-bass level near the crossover
frequency. Set the control to the position with the highest/loudest amount of bass.
Play a test signal (e.g. pink noise) through only 1 speaker at a time. If using your receiver, you may
-
need to enter it's setup mode to perform this function.
Place an SPL meter in your typical listening position, approximately at ear height (use of a tripod may
-
be required), and set to "C" weighting and "Slow" response (if those settings are available)
Adjust volume to a modest level -typically 75-85dB (loud enough to clearly hear, but not excessively
-
loud)
Adjust controls as necessary to play the same test tone through each speaker and subwoofer/-s in the
-
system, 1 speaker at a time.
Adjust the individual channel gain/trim of your equipment to obtain the same SPL reading from each
-
A home theater receiver may walk you through portions of this procedure. Follow any instructions from your
receiver's owner's manual as applicable to your system setup. Once finished, listen to some familiar music and
movie tracks. Minor adjustment of the levels may be desired. Do not be afraid to experiment with adjustments
and try different EQ settings to find what may improve the sound in your system and room the best!
Volume, phase and crossover frequency (also placement of listening position and placement of the sub) are
depending on each other, if one of these parameters is change the other are also changed. I.e. if the crossover
frequency is changed it also influences the volume and phase, so they need to be compensated for this effect.
In a room there is never any absolute correct phase over the whole frequency range, phase needs to be set
to arrange the best result over the whole frequency range.
There are limitations on how well the bass management works in a receiver/processor. The settings for the
subwoofer/-s might need to be adjusted manually either on the subwoofer/-s OR preferably in the receiver/
processor. For some cases when having only one "SUBWOOFER" output jack and multiple subwoofers and
the subwoofers are not placed symmetrically in the room (e.g. having an opening on one side of the room) you
might need to apply different settings for the "PHASE", "VOLUME" and EQ setting on the subwoofers. There
is also the option to use one of our measurement systems Room Analyzer II / II Pro. They are excellent tools
when optimizing and setting up subwoofer/-s or other speakers in a system. Do not be afraid to experiment
with slight adjustments to find what may improve the sound in your system and room the best way.
