EXPERIMENT ON ROOM LOCATION FOR THE XLS SUBWOOFER BOX
CORNER PLACEMENT
RECOMMENDED LOCALES
I CANNOT HEAR THE SUB?
The biggest impediment to good quality bass from your subwoofer usually has little to do with the subwoofer itself, but its location
within the room. The problem is that a sub produces extra long wave lengths (bass) that form "Standing Waves" in the room,
resulting in a potentially uneven distribution of sound level at your favourite listening position. Some attention to the location of the
subwoofer can help dramatically improve your listening experience and achieve remarkable improvements in sound quality.
We recommend that you keep your XLS1000 away from the corners by at least two feet. Corner placement can increase the bass
output, but this location can excite large amounts of unwanted room resonances that will rattle objects and may give a boomy note
to your bass sound. Try
as an experiment. You may and like this setup, you are the final judge. Just watch that crockery!
In
, you are placing the XLS1000 so that the distance from the subwoofer to the nearest wall and its opposing wall is
different. This will stagger the standing waves so that they don't compound up on top of each other, produce rattling resonances.
, trying different locations for both you and the sub will show benefits of what's possible and thus help in
resolving a final location with minimal compromises. Locating the XLS1000 toward the front, as near to your main speakers as
possible is also recommended. Remember also to be careful not to obstruct the rear firing woofer, this is the subsonics.
The XLS1000 is an exceptionally clean, distortion-free subwoofer. As a result, it can be quite difficult to judge the bass content and
correct location of this sub and therefor feel immediately satisfied with your location decision. After all, subsonics are felt not heard!
The subwoofer location experiment may require some living with, and along with the adjustments of level controls, etc, the final
setup may take some extra time and many different media sources before you are generally satisfied that your getting maximum
sound quality from your XLS1000. Although, if you cant exactly here the sub, its probably perfectly tuned and in the best location!

S200W AMPLIFIER CONNECTION & ADJUSTMENTS
HOME THEATRE
The S200W included with the XLS1002 is a 200 Watt RMS amplifier
capable of producing clean audio from 180Hz down to below 20Hz.
For home theatre, connect the S200W via twin RCA to a single RCA
adaptor into the SUBWOOFER output on your home theatre amplifier.
Adjust the FREQ to maximum (180Hz) as the bass filtering is done by
your home theatre amp (See its instruction manual for details).

HIGH-END AUDIO AMP & PRE-AMP COMBINATION
Similar to above. Connect to the amplifiers stereo PRE-AMP outputs.
Use RCA splitters as we recommend NOT connecting to the OUTPUT
on the S200W as it is NOT high-pass output filtered. Once attached,
adjust the S200Ws' FREQ. control to suit your main speakers.
eg. Very small satellite mains would require about 100 to 150Hz.
Full sized mains would require a lot lower, say 50Hz or less.
Adjust the FREQ control until you are happy with the overlap. That is
that there is minimal sound being produced by both speakers which
may give you a boomy sound at this crossover point. Adjust to ear.

PHASE SWITCHING
VIDEO-AUDIO MODE
Simply try it
and
of phase; whichever way has the most bass
is the right way. If it's too much bass, try adjusting the FREQ.
or just turn the subs gain down.
"VIDEO MODE" is a subsonic filter (<20Hz) to protect your XLS1002
from excessive cone movement. If you are in a small or difficult to tune
room, or if you are listening to ridiculously loud music or special
effects, or if the CD or Turntable keeps skipping, or your neighbours
keep complaining, you may wish to switch in the Sub-Sonic Switch to
"VIDEO" mode to protect your unit from damaging sub-sonic energies.
