M-AUDIO Studiophile SBX - Manual (Page 12)

If your satellites are properly damped at the bass response as shown in curve
“a,” set the two crossover frequencies to be identical. If your satellite speakers
are under-damped (boomy sounding) as shown in curve “b,” experiment with
setting the Satellite crossover frequency control higher. If they are over-damped
(dry sounding) as shown in curve “c,” experiment with a lower setting. You may
want to note the final control settings in case they are accidentally altered.
Note: In the event that you do choose an external form of bass
management, you will likely need to set the Subwoofer LPF cutoff
frequency to 180Hz. If you choose not to use the SBX internal bass
management or an external form of bass management, you may want
to begin with a Subwoofer LPF cutoff frequency of 120Hz and experiment up
or down until you reach your desired sound.
Troubleshooting & Technical Support
Avoiding Problems with Turntables
Since the SBX can produce a considerable output level at low frequencies,
acoustic feedback via a turntable can occur. To ensure that this is not the case,
perform the following test at installation of the SBX.
Set up the equipment for playing a record. Place the stylus on a non-rotating
record (disconnect the turntable power cord if necessary). Tap the turntable
