AIRMOTIV XS SUBWOOFERS
4. Turn the Volume Control up until the amount of bass sounds more or less correct.
5. Use the Phase Control to adjust for the MOST bass in the frequency range where your
subwoofer and main speakers overlap.
6. Fine tune the setting on the Volume Control so that the amount of low bass and middle
frequencies seem about right in proportion to each other. At this point you'll probably have a
bump in the frequency response where the subwoofer and your main speakers overlap.
7. Now, turn the Crossover Control to the left to reduce the overlap between your sub and
main speakers until everything sounds best. (At this point you're lowering the crossover
frequency to eliminate the overlap between the subwoofer and your main speakers.)
8. If necessary, you can adjust the Volume Control one final time to get things just right.
9. Finally, after you've adjusted your XS subwoofer for the flattest possible response,
use the LF Boost control to fine tune the low bass response to your room and 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.
