RECOMMENDED SETUP PROCEDURES
Subwoofer System Setup:
Once you have set the controls on your home theater receiver or preamp/
processor and your subwoofer to the settings recommended on pages 24 and 25,
you are ready to begin setting up your Dominion™ for optimum performance.
1) Level Setting
Using familiar music or movie material with deep bass content, adjust the
subwoofer level to blend with the other speakers using your receiver or preamp/
processor’s subwoofer level control.
In the unlikely event that the subwoofer level control in your receiver or
preamp/processor cannot be turned up enough to level match the Dominion™,
return that control to “0.” Instead, use the “Master Level” control on your
Dominion™ to level match the subwoofer with the other speakers.
For more detailed information on level setting controls of your Dominion™,
please refer to the “Master Level” section on page 14 of this manual.
2) Polarity and Phase Adjustment
It is oen helpful to have a second person operating these controls so that you
can easily hear the changes from the primary listening seat.
Listening to familiar source material (preferably music with good upper bass
and midbass response), ip the “Polarity” switch from “0” to “180” and listen for
dierences. e correct setting will sound most natural with the best upper bass
punch and articulation. If both sound similar, choose “0.”
Once Polarity is set, use the same music material to audition dierent “phase
(deg.)” control settings and choose the one that further enhances the upper and
midbass response. If you cannot hear a dierence, set the control to “0.”
3) Experiment with alternative subwoofer locations (if necessary).
If you are satised with the basic performance of your subwoofer, you are
ready to move on to the next step. If not, we recommend that you experiment
with the position of your subwoofer until you are pleased with its basic
performance. Experimenting with placement is KEY to a superior sounding
system. Moving the subwoofer just a few feet can have a signicant eect on
the smoothness of the bass. For each new position, start with the “Polarity” and
“phase (deg.)” controls at “0” and repeat the setup process beginning with Step 1.
is completes the basic setup process! You can achieve further
improvements through the correct use of processing built into your receiver or
preamp/processor. Consult with your Authorized JL Audio Retailer if you require
further setup assistance.
