AIRMOTIV SUBWOOFERS
- Adjust the Phase Control to the setting where you hear the MOST bass in the frequency range
where the sub overlaps with your main speakers.
- 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.
- 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 sub 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 sub and main
speakers. A good rule of thumb is that the bass should sound solid, but you should not hear the
sub as a distinct separate sound source; try turning the Volume Control up until you barely notice
the sub, then back down a tiny bit.
- Finally, after you've adjusted your Airmotiv sub 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 sub 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 Airmotiv sub 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 Sub Manually
If you're connecting your Airmotiv sub to a stereo system that doesn't have a subwoofer output,
you'll be using the controls on the Airmotiv sub to make it fit perfectly with your main speakers.
- First you'll need to take a set of main outputs and connect them to BOTH inputs on your
AirmotivX 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 Airmotiv sub.
- 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.
- Now, play some music with plenty of bass, and that you are familiar with.
