AIRMOTIV XS SUBWOOFERS
4. Adjust the Phase Control to the setting where you hear the MOST bass in the frequency
range where the subwoofer overlaps with your main speakers.
5. Use the adjustments on your receiver or pre/pro to dial your settings in perfectly, or
run the automatic room correction and let it do all the work for you. The procedure will be
slightly different on each system because each piece of equipment offers different manual
controls and different automatic options.
If your AVR or pre/pro has a full range subwoofer output (but not bass management), then
there’s one additional step.
5a. AFTER you’ve set the Phase Control for the most bass, go back and adjust the Volume
and Crossover Controls for the best sound. The Crossover Control controls the overlap
between your subwoofer and your main speakers; you want to set it so that your subwoofer
blends smoothly with your main speakers, without a bump or dip where they overlap, and
without a sharp transition from one to the other. The Volume Control is used to set the
relative level between your subwoofer and main speakers. A good rule of thumb is that
the bass should sound solid, but you should not hear the subwoofer as a separate sound
source
6. Finally, after you’ve adjusted your XS subwoofer for the flattest response, you can
use the LF boost control to fine tune the very low frequency response to your personal
preference.
Note: The way your main speakers and subwoofer blend together will sound slightly different
at different locations in the room. These adjustments should be made by listening at your
normal listening location. If your equipment is located across the room, walk back to your
favorite chair and listen to the results from there each time you make an adjustment.
Note: After you’ve configured everything on your pre/pro, or used your automatic room
correction to do so, you should AVOID changing the Crossover and Phase Control settings
on your XS subwoofer as this will change the way it sounds. However, you may use the
Volume Control to increase or reduce the overall amount of bass to suit your taste, and the
LF Boost control to fine tune the amount of low bass.
Configuring your Airmotiv XS Subwoofer Manually
If you’re connecting your XS subwoofer to a stereo system that doesn’t have a subwoofer
output, you’ll be using the controls on the XS subwoofer so that it blends smoothly with your
main speakers.
1. First you’ll need to take a set of main outputs and connect them to BOTH inputs on your
XS subwoofer. It doesn’t matter which channel you connect to which input since they’re
summed together. If you only have one set of main outputs, you can use a pair of splitter
cables to send a copy of those signals to your XS subwoofer.
2. Start with the Volume Control all the way down; with the Phase Control set to 0 degrees,
and with the Crossover Control set to the far right - to 150 Hz.
3. Now, play some music with plenty of bass, and that you are familiar with.
