Variable Tuning Ultra-X12 Subwoofer 15
Using More than One Sub
To connect more than one subwoofer to your receiver or
processor you can use a Y-adapter. Insert the single male
end of the adapter to the subwoofer output of your receiver
or processor. On the opposite end of the Y-adapter you will
now have two separate subwoofer outputs, one for each
sub. Be sure to use a Y-adapter that is of equal or better
quality than the subwoofer cables you intend to use.
Alternatively, you can use the THRU jack on the rear panel
of the Ultra-X-12 to daisy chain one or more subwoofers.
If setting the subwoofers in the corners or middle of the
walls as shown above does not produce the best results,
you can use the same procedure used for determining the
placement of the first subwoofer on the previous page.
However, the second sub should be placed in the seating
area outside of the “sweet spot” where good bass response
is also required.
Walk around the room until you find the area where the
bass sounds the best, just as described in the process for
locating a single sub. This spot will almost always be differ-
ent than the one that was best for the primary sub.
Using two or four subwoofers Connecting two or four subwoofers
The subwoofers can either be placed in the corners of
the room, for boosted output, or in the middle of the
walls, for smoother response.
Research has found that using two or four matching subwoof-
ers results in much smoother bass response across a large
seating area. If you want to make the bass sound good for
several listeners (and not just you), this is worth exploring. You
can place the subwoofers in the corners of the room. This will
boost perceived output, but may compromise smoother bass
response. Placing the subwoofers in the middle of the walls
would be more desirable for smoother bass response. While
you might assume additional subwoofers are for added SPL,
the greatest benefit will actually be smoother bass response.
Room shape, the cubic volume of the room, furniture, floor
coverings and even wall and ceiling material all play a roll in
bass performance. These factors create peaks and dips in the
amplitude level of low frequencies at different points in the
room. That said, two properly positioned subwoofers will
distribute the bass throughout the room with greater accuracy
than a single sub. For this reason, many professional acousti-
cians and installers recommend more than one subwoofer. The
final result is that you will create a much larger “sweet spot”
where the bass is powerful, but more importantly, smooth and
consistent. If near perfect bass response is your goal, consider
using two or more Ultra-X12 Subwoofers.
When calibrating the final levels of each subwoofer,
you may want to reduce their output to compensate for
the added 3 or 4 dB of gain created by using multiple
subwoofers.
When locating and calibrating the level of each additional
subwoofer be sure to turn off the other sub(s). This will
help you to determine ideal placement without being mislead by
the response of the first sub.
If you sense a loss of bass output after properly locat-
ing and calibrating the additional subwoofers, the likely
problem is that one or more of units are out of phase with
each other. If this occurs, try flipping the phase switch on
the back of each of the subs until the bass returns.
For more information regarding setting the phase control
and volume level of the additional subwoofer(s), please
refer to “Setting the Phase Switch,” on page 12, and “Set-
ting the Volume Level,” on page 13.
