so called 'subsonic' filters are used to remove the lower bass frequencies, generally to prevent a subwoofer from playing below tuning in a ported box.
If you have a setup where you are ported above 30hz then you could run into trouble with the sub unloading (which can cause mechanical damage)
If you have a setup where you are ported above 30hz then you could run into trouble with the sub unloading (which can cause mechanical damage)

Unfortunately AFAIK there is no standalone SS filter available for mobile use....if you are running a sealed box it is not as much of an issue, a ported box will be a problem if you play loud music or test tones below the tuning frequency.......
