7567 Subwoofer Lowpass filter?
The laptop has a built in subwoofer and I'm trying to adjust the lowpass filter. I was wondering if there's an option built in? If not, can it be added somehow? Loud volume causes the subwoofer to distort because the sub isn't designed for those frequencies.

It is virtually guaranteed that Dell would not have included a lowpass filter for that system's subwoofer. Even most (all?) home theater and PC multimedia set subwoofers only offer highpass filters with their cutoff frequency knob/setting, not lowpass filters. Same goes for AV receivers when dealing with subwoofer settings. If you wanted this, you'd have to find some sort of third-party application that could put a low-level audio driver into the system in order to remove those frequencies, but more realistically if your subwoofer is distorting, you may be running the overall volume too high, or else that's just how the subwoofer responds. Your expectations for quality bass frequency reproduction may be too high for a subwoofer that fits inside a laptop.

If you look at the properties of the speakers, there is a level tab which should have a volume level for the subwoofer.
If not that, you might use the equalizer in Waves to limit the bass frequencies. Make sure and save the profile.
As far as I know, the system uses the stereo input and pulls out bass frequencies and sends them to the subwoofer. Maybe that process is not working correctly. If the subwoofer isn't rattling or causing some vibration noise, actually distorting a waveform may be processor lag.
I suppose I should acknowledge, the 7577s do not have the subwoofer, maybe your experience is why. When I listen to music on my 7567, it does sound much better with the subwoofer. I may even angle the bottom of the unit up so sound doesn't have to bounce off the tabletop.
